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.

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 06-07-30-007A – Harsh 1-2 shift with P0894 DTC – 4L60E Transmission | 4L65 Transmission | 4L70E Transmission

Problem – Drivers may experience an unusually harsh 1-2 shift with a P0894 DTC
Solution – Replace the TCC enable solenoid and/or wiring harness

TSB 08-07-30-008B – Diagnostic information for P0894 and P1870 DTC – 4L60E Transmission | 4L65 Transmission | 4L70E Transmission
2003-2007 GM Passenger Cars and Light Duty Trucks – 2003-2007 HUMMER H2 – 2006-2007 HUMMER H3 – 2005-2007 Saab 9-7X – with 4L60-E, 4L65-E or 4L70-E Automatic Transmission (RPOs M30, M32 or M70)
Problem – This relates to drivers who experience unusually harsh 1-2 shifts, along with a P0804 and/or a P1870 DTC.
Solution – It is possible that a leaking TCC solenoid, a torque converter clutch valve or damaged turbine shaft O-ring seal could cause these two diagnostic trouble codes. However, it could also be caused by a failed torque converter.

TSB PIP4051C – Harsh Shifting – 4L60E Transmission
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 08-07-30-001 – 4L80E Transmission
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 – 4L80E Transmission
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 08-07-30-016 – Slipping, refusal to shift, overheating – 4L80E Transmission
Problem – Slipping between the gears, overheating, refusal to shift out of a gear, and/or DTC P0894 or P0218, may be because by friction material debonding from the torque convertor clutch (TCC).
Solution – If the friction material has circulated throughout the transmission, the entire transmission may need to be replaced. It is possible to remove the material from the internal components (like transmission cooler lines and the valve body), but it depends on the extent of the damage.

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.

Common GMC Savana 2500 HD Transmission Problems

Intermittent harsh shifting – 4L60E Transmission
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.

Can I drive with a transmission problem?

If your GMC Savana 2500 HD can still make it up and down the road, you might say “It’s fine, I’ll just drive it until I can get it fixed”. But that is not always a good idea, depending on the symptoms. You see, there are a lot of (very expensive) moving parts inside of a transmission, and if something isn’t right, continuing to drive with a transmission problem could damage something else.

How often does a GMC Savana 2500 HD transmission need to be replaced?

The overall lifespan of a GMC Savana 2500 HD transmission largely depends on how well it was maintained. Factory design flaws also factor into this equation, along with how/how hard you drive. But on average, we’ve seen the GMC Savana 2500 HD transmission last for between 130,000-180,000 miles. A high quality replacement transmission however, can last considerably longer if all of the factory design flaws have been addressed and the vehicle has been maintained.

How are GMC Savana 2500 HD transmission issues diagnosed?

It is fairly easy to guesstimate what the root cause of your GMC Savana 2500 HD transmission problems might be, but you won’t truly know unless you have the right tools and experience. A good mechanic or transmission repair center will be able to connect your truck to a computer and find out which diagnostic trouble codes (DTC’s) have been stored. Once they know what to look for, they can perform a visual inspection to verify the problem.

How is a GMC Savana 2500 HD transmission replaced?

In order to replace your GMC Savana 2500 HD 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 GMC Savana 2500 HD Transmission Problems

Solution A: Buy a Used GMC Savana 2500 HD Transmission

The quickest way to fix your transmission problems is to simply buy a used transmission or used transmission. These can be found at most junk yards, and they often come with a 30-90 day warranty. However, there’s no way to determine the actual condition of the internal components, so you could be spending a bunch of money to have the exact same problems. Plus, that warranty only covers the transmission if it’s defective, not the labor costs that you’ll have to pay.

Solution B: Buy a Rebuilt GMC Savana 2500 HD Transmission

Another option would be a rebuilt transmission or rebuilt transmission. A local repair shop will remove your transmission, then install a bunch of new parts during the rebuild. The problem here is, the skills and experience of each transmission rebuilder will vary widely from shop to shop, so you could have problems from something that wasn’t adjusted properly. And the 1-2 year warranty might only cover you at certain transmission repair shops, in a specific geographical area.

Solution C: Buy a Remanufactured GMC Savana 2500 HD Transmission

Many owners depend on their vehicle to commute and get things done. Their gasoline engines are designed to go 100’s of thousands of miles, so it makes sense to invest in a remanufactured transmission.

I Joined the discussion… Most likely If I understand you correctly.
Sounds like your mechanic wants you back to start the last part of the Clutch job (Part 1) because, you did not pay enough money to get the job done right the first time or rather did not pay for the Road test and Adjustment of The Clutch release system Part 2 .

The Clutch release system is either not working or not adjusted properly.

The Clutch release system is in need of replacement or adjustment after a friction and pressure plate replacement. And now may need a “though out bearing”, as well.

The release system pulls the Pressure plate away from the Friction disk
putting the Transmission front main drive shaft in Neutral. So, you may shift Gears or begin the Car Moving from a stop as you let your foot off the Clutch pedal inside your Car☺

For the Quick Answer; Pour some Dot4 Brake fluid in The Clutch release system
reservoir and fill to the Full line and bleed the Air outta the system.

If it doesn’t work or have a reservoir or is already full?
!ASAP See your Mechanic for an adjustment ASAP!

Will not down shift upon Throttle demand and Will not down shift with shift lever.
Will only down shift with vehicle speed slowing down.
3) Shifts correctly then, changes while sitting still in traffic to Hard shift 1-4 and not lock TC
Will hold shifts until Throttle demand and then Will up shift under throttle load
(not with shift lever).
Will only down shift with vehicle speed slowing down.
4) Shifts correctly hard 1-4 and lock TC all below 30mph will not down shift as above, will not
unlock torque converter until vehicle slows down.
Will only down shift with vehicle speed slowing down
5) Shift Hard 1-4 and not lock TC, turn off engine and restart; Shifts correctly.
6) Shifts correctly then, changes After 15 miles and shut down and Restart to Hard late shifts
1-4 and no lock Torque converter
Will not down shift upon Throttle demand and Will not down shift with shift lever.
Will only down shift with vehicle speed slowing down.
Turn off engine again and restart; Shifts correctly then repeat Items 2-6.
7) If engine temperature is maintained 170-190 degrees seems to shift correctly.

TC=Torque Converter

The Van has 265,000 miles Engine and Transmission replaced at 160,000 miles, no oil drips,
oil in Engine and Transmission is kept as close to looking like the Oil that came outta the Can
as I can and no codes.
