Chevy Suburban Technical Service Bulletins (TSB)

TSB PIP4051C – Harsh Shifting – Chevrolet Suburban 4L60E
Problem – Unusually harsh gear changes, combined with a P0717 DTC for an input shaft speed sensor error, are often caused by damage to the ISS sensor wiring.
Solution – If wire damage is found (usually to the white wire), the wiring and sensor will have to be replaced. The pump cover should also be examined for sharp points/edges that could damage the wiring. If any are found, they should be smoothed with a file.

TSB 01-07-30-002C – Transmission stuck in third gear with inoperable instrument cluster and multiple DTC’s – 4L60E Transmission & 4L65 Transmission
1999 – 2003 Cadillac Escalade – 2002 – 2003 Cadillac Escalade EXT – 2003 Cadillac Escalade ESV – 1997 – 2003 Chevrolet Silverado – 1997 – 2003 Chevrolet Suburban – 1997 – 2003 Chevrolet Tahoe – 1997 – 2003 Chevrolet Blazer – 1997 – 2003 Chevrolet Express – 1997 – 2003 Chevrolet S10 – 2002 – 2003 Chevrolet Avalanche – 2002 – 2003 Chevrolet Trailblazer – 2002 – 2003 Chevrolet Trailblazer EXT – 1997 – 2003 GMC Sierra – 1997 – 1999 GMC Suburban – 1999 – 2003 GMC Yukon XL – 1997 – 2003 GMC Yukon – 1997 – 2001 GMC Jimmy – 1997 – 2003 GMC Savanna – 1997 – 2003 GMC Sonoma – 2002 – 2003 GMC Envoy – 2002 – 2003 GMC Envoy XL – 1997 – 2003 Oldsmobile Bravada
Problem – Vehicles equipped with the 4L60E and 4L65E transmission may become stuck in third gear, the instrument cluster may not function, and the following DTC’s may be set: P0740, P0753, P0758, P0785 and P1860.
Solution – The most likely cause of this transmission problem is a blown fuse or an open on circuit 1020 between the fuse panel and the transmission. If no battery voltage is found at the fuse, the ignition switch will need to be replaced

TSB 01-07-30-023B – Harsh 1-2 upshift with P1870 DTC – 4L60E Transmission RPO M30
1996 Buick Roadmaster – 1996 Cadillac Fleetwood – 1999-2000 Cadillac Escalade – 1996-2000 Chevrolet Camaro – 1996-2000 Corvette – 1996-2000 Pontiac Firebird – 1996-2000 Chevrolet and GMC Light Duty Truck Models – 1996-2000 Oldsmobile Bravada
Problem – Drivers may experience an unusually harsh 1-2 shift because the ECU has commanded maximum line pressure in order to compensate for excessive wear in the bore that contains the TCC isolator and regulator valves inside of the valve body.
Solution – Replace the 4L60E valve body with revised TCC regulator and isolator valves.

PIP5071 – Squawking noise on the 2-3 shift – Chevrolet Suburban 4L60E
Problem – An unusual squawking or groaning noise may be heard on the upshift from 2nd to 3rd gear.
Solution – The 3-4 friction and steel plates, clutch plate, apply plate, and selective backing plates will have to be replaced.

TSB 08-07-30-027 – No movements when transmission is shifted into Drive or third – 4L60E Transmission – 4L65E Transmission – 4L70E Transmission
1982-2005 GM Passenger Cars and Light Duty Trucks: 2006-2007 Buick Rainier – 2006 Cadillac Escalade, Escalade ESV & Escalade EXT – 2006 Chevrolet SSR – 2006-2008 Chevrolet Avalanche – 2006-2008 Chevrolet Colorado – 2006-2008 Chevrolet Express – 2006-2008 Chevrolet Silverado Classic – 2006-2008 Chevrolet Silverado – 2006-2008 Chevrolet Suburban – 2006-2008 Chevrolet Tahoe – 2006-2008 Chevrolet TrailBlazer – 2006 GMC Yukon Denali – 2006 GMC Yukon Denali XL – 2006-2008 GMC Canyon – 2006-2008 GMC Envoy – 2006-2008 GMC Savana – 2006-2008 GMC Sierra Classic – 2006-2008 GMC Sierra – 2006-2008 GMC Yukon – 2006-2008 GMC Yukon XL – 2006 Pontiac GTO – 2006-2007 HUMMER H2 – 2006-2008 HUMMER H3 – 2006-2008 Saab 9-7X – with the 4L60, 4L60E, 4L65E or 4L70E Automatic Transmission (RPOs MD8, M30, M32, M33 or M70)
Problem – It is possible to experience no movement when the transmission is shifted into Drive or the 3rd gear position. It is possible to experience normal operation when the transmission shifted into second, first or reverse.
Solution – Replace the forward sprag assembly

TSB 00-07-30-022D – No reverse, second or fourth gears – 4L60E Transmission & 4L65E Transmission
1993 – 2005 GM passenger cars and light duty trucks
Problem – Drivers may experience the loss of reverse, second and fourth gears. First and third gears will seem to function normally
Solution – The reaction sun gear may fail inside of the sun shell. It will need to be replaced with a stronger heat-treated 4L60E / 4L65 sun gear.

TSB 08-07-30-001 – Chevrolet Suburban 4L80E
Problem: Harsh or delayed shifts, slipping, no forward/reverse gears. Possible DTCs: P0741, P0742, P0751, P0752, P0756, P0757, P0894.
Solution: Rebuild or replace the valve body.

TSB 08-07-30-015 – Chevrolet Suburban 4L80E
Problem: Harsh shifts, delayed 2-3 shifts, 2-3 shift flare, no 3rd gear, slips in 3rd gear or reverse. Possible DTC 0757.
Solution: If none of the issues described in Bulletin 08-07-30-001 are present (debris in #11 checkball, leak in oil circuit, damage to the direct clutch), then replace the 2-3 shift solenoid due to a possible sticking pintle.

TSB PI488C – No forward or reverse and/or slipping – 6L80 Transmission | 6L90 Transmission
2010 – 2014 Cadillac CTS-V – 2010 – 2014 Cadillac Escalade (all models) – 2010 – 2013 Chevrolet Avalanche – 2010 – 2014 Chevrolet Camaro – 2010 – 2014 Chevrolet Corvette – 2010 – 2014 Chevrolet Express – 2010 – 2014 Chevrolet Silverado – 2010 – 2014 Chevrolet Suburban – 2010 – 2014 Chevrolet Tahoe – 2011 – 2014 Chevrolet Caprice PPV – 2014 Chevrolet SS – 2010 – 2014 GMC Savanna – 2010 – 2014 GMC Sierra – 2010 – 2014 GMC Yukon – 2010 – 2014 GMC Yukon XL – 2010 – 2014 GMC Yukon Denali

Problem – Trucks equipped with the 6-speed 6L80 or 6L90 transmission may experience no forward or reverse engagement, or slipping between the gears.

Solution – This problem could be caused by a cracked or split transmission filter. If this is the case, the transmission pump should be disassembled and inspected for possible damage. Inspect for any of the following conditions: – scored pump rotor or pump vanes – scored pump cover or pump rotor pocket – cracked pump slide.

The transmission should also be evaluated for any possible distress to the clutches. GM’s testing and analysis found that split or damaged filters may be caused by a damaged transmission pump. This can send a high pressure fluid spike down the filter neck on a cold start, resulting in the filter body cracking or the filter seam splitting. The filter is not defective and this is not a filter quality issue. Important: Do not replace the filter without inspecting the pump. Failure to inspect the pump and clutches could lead to a repeat of this condition.

TSB 09-07-30-004J – Slips in Reverse or Third, Delayed Reverse or Drive Engagement, DTC P0776, P2715, P2723, Harsh 2-3 Shifts – 6L80 Transmission | 6L90 Transmission
2006-2009 Cadillac STS-V – 2006-2009 Cadillac XLR – 2006-2009 Cadillac XLR-V – 2007-2008 Cadillac Escalade, Escalade ESV, Escalade EXT – 2006-2009 Chevrolet Corvette – 2007-2008 Chevrolet Silverado – 2008 Chevrolet Suburban – 2007-2008 GMC Sierra – 2007-2008 GMC Sierra Denali – 2007-2008 GMC Yukon Denali – 2007-2008 GMC Yukon XL Denali – 2008 GMC Yukon XL – 2008-2009 HUMMER H2 – 2008-2009 Pontiac G8
Problem – Vehicles equipped with the 6L80 or 6L90 transmission may slip when Reverse is selected or have no/delayed reverse engagement, harsh shifts from 2-3 / 4-5 or slips while in fifth, and slipping acceleration when passing. Possible DTCs include P0776, P2715 or P2723.
Solution – This transmission problem may be caused by a cracked 1-2-3-4 / 3-5-R clutch housing.

TSB 16-NA-014 – Delayed engagement after sitting with the engine off
Problem – Drivers may experience a pronounced delay in forward or reverse gear engagement after shifting from Park. This condition typically occurs when the vehicle has been sitting for several hours with the engine off (like overnight).
Solution – In order to correct this common 8L90 transmission problem, a new stator shaft support assembly will have to be installed.

PIP5437A – Harsh shifts
Problem – One of the more common 8L90 transmission problems is excessively hard or abrupt gear changes.
Solution – The TCM may need to be recalibrated with the latest control software. It could also be caused by one or more of the clutch fill times not being learned by the TCM. In which case, the Service Fast Learn (SFL) procedure will have to be performed.

TSB – 16-NA-404 – Erratic shifting behavior
Problem – Drivers may experience harsh shifts, delayed shifts, unexpected downshift, stuck in a gear and/or hesitation to shift. The following DTC codes may also be set: P0747, P0777, P0797, P2715, P2724.
Solution – These problems may be caused by a programming error in the TCM, which will require a software update.

Common Chevy Suburban Transmission Problems

Intermittent harsh shifting – Chevrolet Suburban 4L60E
Problem – A common 4L60E transmission problem is an intermittent hard 1-2 shift, often accompanied by engine bogging. This condition can be caused by the torque convertor clutch applying during the shift.
Solution – To remedy the problem, the wiring harness needs to be inspected from the transmission case connector to the rear of the engine on the driver side. It’s possible that the wires for the TCC solenoid and pressure control solenoid have become frayed on a body seam. If this is the case, the wiring will need to be repaired, and the harness repositioned.

Solenoid DTC’s – Chevrolet Suburban 6L90
Problem – A number of diagnostic trouble codes, including P0776, P0796, P2714 and P2723, can be caused by a pressure leak at the end of the clutch regulating valve.
Solution – The bore plug will have to be replaced with updated versions, or modified to accept an O-ring kit.

Can I drive with a transmission problem?

Although it may feel like you could keep driving, Chevrolet Suburban transmission problems can easily sneak up and destroy your day. You see, transmission parts have to endure extreme heat and friction, and these conditions can quickly deteriorate if everything isn’t working correctly. These elevated transmission fluid temperatures can severely damage other parts like seals and clutch material. So do the wise thing and have an experienced mechanic look at the problem immediately.

How often does a Chevy Suburban transmission need to be replaced?

Obviously, the better you take care of something, the longer you’ll have it. This is especially true when it comes to transmissions, and a Chevrolet Suburban transmission is no different. When properly maintained and driven respectfully, a Suburban transmission can last anywhere from 130,000-220,000 miles. A remanufactured Chevy transmission on the other hand, can last considerably longer.

How are Chevy Suburban transmission issues diagnosed?

To figure out what is causing your Chevrolet Suburban transmission problems, a mechanic will connect an OBDII scan tool to the truck and download the diagnostic trouble codes. A visual inspection will be needed to confirm the diagnosis, especially if there are no relevant DTC’s stored in the ECU.

How is a Chevy Suburban transmission replaced?

In order to replace your Chevy Suburban transmission, the truck has to be lifted from the ground in order to gain access to all of the parts that will need to be unbolted. Then the transmission can be lowered to the ground (typically with a transmission jack), so the new transmission can be installed. Once it is in place, for the 6L80, the vehicle PCM will have to be reprogrammed / reflashed to accept the new transmission using the latest GM subscription.

Recommendations for Chevy Suburban transmission issues?

To save time and get back on the road faster, have your 17-digit truck VIN# handy and you can get an online quote for a reman Chevy Suburban transmission here, then find a local shop using our Find a Shop guide to install it for you.

How to Solve Chevy Suburban Transmission Problems

Solution A: Buy a Used Chevy Suburban Transmission

One of the most popular solutions for severe Chevrolet Suburban transmission problems is buying a used 4L60E / used 4L80E / used 6L80E / used 6L90 / used 8L90 transmission from the local junkyard. They are easy to find, and most come with a replacement warranty (they will swap out the transmission if it does not work right). But the problem is, you don’t know what the condition of the internal components actually are. So you could wind up with the same, or even worse problems than you have now. And that replacement warranty probably does not cover labor charges.

Solution B: Buy a Rebuilt Chevy Suburban Transmission

A rebuilt 4L60E / rebuilt 4L80E / rebuilt 6L80E / rebuilt 6L90 / rebuilt 8L90 transmission is certainly a better option. But you better hope that the mechanic building it, knows what they’re doing. And most rebuilt transmission warrantees are only honored at the shop that built it. So you’ll be without warranty coverage if you travel.

Solution C: Buy a Remanufactured Chevy Suburban Transmission

To get a more permanent solution to your Chevrolet Suburban transmission problems, you may want to consider investing in a remanufactured 4L60E / remanufactured 4L80E / remanufactured 6L80E / remanufactured 6L90 / remanufactured 8L90 transmission. These are often built in a factory, using the much higher quality components. The better ones are also modified to correct for factory design flaws, and dyno tested to ensure proper operation and tuning. Plus, you may be able to get a much better warranty too.

There is a whining sound from the TC when facing up hill the Suburban rolls backward give it a little gas and the transmission engages with a hard CLUNK. it has trouble shifting and is getting worse. The trans temp is under 180 and appears to have plenty of trans fluid.

Any Idea what I’m in for?
I bought this a couple weeks ago from a local family dealer.

2003 suburban 5.3 with the 4l60e. Driving and lost 3rd and 4th in drive. I have 1st and 2nd and reverse. I can manually do the 1st and 2nd but as soon as I try 3rd or drive it redlines as if thrown in neutral. Fluids are clear, clean and free of leaks. Fuses are fine. New filter and solenoids. No codes showing up.
I’m over stressing about this dang thing but if I have ti drop a new trans in it, I will be doing it myself and learning first hand. If ya’ll have any advice or direction for me to try before that.. PLEASE share!

2003 Chevrolet suburban four-wheel-drive 5.3 engine 4L60 E tranny. All of a sudden when put in overdrive or drive The truck would just sit and sound like the transmission was slipping. You could manually drop it to first gear start the vehicle moving then completely shifted into overdrive the truck would move and shift through the gears normally when slowing down it would downshift normally until you got down to a very low speed then would kick in the neutral and slip. Replace fluid and filter ran it a little bit and manually shifted it down in the first gear to make it take off and Drive a few times and then into overdrive. After a few minutes it started acting normal again for a year or two. Was coming home one day pulled into the driveway hit a small bump and started doing it again. Truck has been parked while I try to figure out if it could be a wiring harness issue a valve body issue or if the whole transmission needs to be replaced. Also instrument cluster went crazy all gauges are messed up and I believe the stepper motors need to be replaced in it and rebuilt but I’m not sure if that might have something to do with the transmission as well. Thank you for any comments or suggestions.

I have a 2011 Suburban. Shifts normally under acceleration,but when coasting speeding up or down feel a vibration around 30 miles an hour until shifts, with harder than normal shifting as speed decreases from third to second to first. No problem noted when accelerating going thru shifting. 160,000 miles. No codes noted. Troubleshooting ideas?

I have an 07 suburban. Reverse is fine and if I shift it manually it’s fine. However if I put it in 4 3 or2 it acts like it’s in neutral. I have no codes. Any suggestions would be greatly appreciated. I’m used to older stuff not familiar with all this electronic stuff.
