Chevy Suburban Transmission Recalls

None Found

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.

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.

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 08-07-30-001 – 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.

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.

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.

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.

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.

I have a 2010 Chevrolet Suburban LTZ and when I shift into drive the car doesn’t shift into gear 2 and it only goes about 30-40 mph with the pedal to the floor. Does anyone know what’s happening or could be wrong
