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.

How to Solve Chevy Express 3500 Transmission Problems
Solution A: Buy a Used Chevy Express 3500 Transmission
The Chevy express 3500 isn’t a vehicle that you drive for pleasure. You got to make money with it, so saving money is very important. Buying a used 4L80E / used 6L90 transmission will certainly seem budget friendly. But when you consider that you don’t know how long it will actually last, you may actually have another expensive repair to make sooner than you think. Plus those junkyard warranties don’t usually cover labor charges for repairs.
Solution B: Buy a Rebuilt Chevy Express 3500 Transmission
Buying a rebuilt Chevy Express 3500 transmission might seem like a much better choice, but this may also get expensive. You see, when rebuilding an existing transmission, most mechanics will use an OE master rebuild kit that returns the transmission back to its stock form. So many of the common Chevrolet Express transmission problems will return. And, the warranty they give you may only be honored at the shop that built it.
Solution C: Buy a Remanufactured Chevy Express 3500 Transmission
In order to completely eradicate any known problems, most remanufactured transmissions are completely blown apart and each piece is inspected and tested to make sure that it’s within specification. Then necessary modifications are made to correct the known issues, and the high-end transmission reman companies will then dyno test the finished product to make sure that it performs with no issue. For the money, a remanufactured Chevrolet Express transmission is hard to beat, considering it can significantly reduce your downtime.
