Chevy Express 2500 Transmission Recalls
Chevy Express 2500 Technical Service Bulletins (TSB)
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 – Chevrolet Express 2500 4L80E
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.

Can I drive with a transmission problem?
Of course you can. But continuing to drive the van when you’re having 4L80E transmission problems or 6L90 transmission problems, can cost you a lot more money in the long run. As those transmission parts continue to break down, it can create a domino effect with other more expensive parts. So do your wallet a favor and have your Chevy Express 2500 transmission problems diagnosed sooner rather than later.
How often does a Chevy Express 2500 transmission need to be replaced?
With proper maintenance, any Chevrolet Express 2500 transmission can last for a very long time. Over the years, we’ve seen the following average lifecycles:
4L80E – 120,000-180,000 miles
6L90 – 130,000-200,000 miles
If you are considering a used transmission, that’s about the mileage that you will see out of one. However, a remanufactured transmission will often last much longer than that.
How are Chevy Express 2500 transmission issues diagnosed?
These vans are fairly straightforward mechanically, so many Chevy Express 2500 transmission problems can be diagnosed with some experience and hand tools. However, later models may require an OBDII scan tool.
How is a Chevy Express 2500 transmission replaced?
Because of its body on frame design, a Chevrolet Express 2500 transmission can be changed by unbolting the 4L80E from the engine, driveshaft and frame. After installing the new transmission, the ECU/TCM may have to be reprogrammed in order to accept the new gearbox.

How to Solve Chevy Express 2500 Transmission Problems
Solution A: Buy a Used Chevy Express 2500 Transmission
Saving money is important to everybody, so getting a used 4L80E / used 6L90 transmission from the local junkyard might seem like a good idea. But you don’t really know what kind of problems that used Chevy transmission might have. So you don’t really know how long it will last, and the junkyard warranty probably won’t cover labor charges to fix it.
Solution B: Buy a Rebuilt Chevy Express 2500 Transmission
Another idea would be to get a rebuilt 4L80E / rebuilt 6L90 transmission from a mechanic or transmission repair center. These have a lot of new parts, and a much longer warranty. However, if the mechanic has used an OE master rebuild kit, then the problems that you’re having now will most likely return in future. Plus, the warranty may only be honored at that one repair shop.
Solution C: Buy a Remanufactured Chevy Express 2500 Transmission
To get the most value for your repair dollars, you’re going to want to consider getting a remanufactured 4L80E / remanufactured 6L90 transmission from a reputable supplier. These have gone through a rigorous remanufacturing process, where every single component has been tested to ensure that it either meets or exceeds OE specifications. Upgrades are often made to correct factory design flaws, and some even offer unlimited mileage nationwide warranties.
