The following is a list of problems and possible solutions, should your 4L80E suddenly start to give you trouble. This article deals with fixing your factory 4L80E to make it as durable and reliable as it should have come from the factory. Most of the problems are electronic in nature and are relatively easy, but expensive, to fix. As such, most of the 1991-1992 454SS trucks came with 4L80E transmissions that had faulty parts from the factory. But while the 4L80E is a strong, heavy-duty transmission, during the first few years of production the 4L80E was not as durable as its design permitted due mainly to faulty parts. The 4L80E, an electronic, overdrive-equipped version of the venerable TH-400, is tough enough to handle just about whatever hell you put it through when built properly. The 4L80E is being found in more and more high performance, race, and tow vehicles over the last few years.

If you don’t know how to replace the shift accumulator along with the springs, check out this tutorial to learn.Heres some info on the early 4L80E transmission problems.
In this case, you can go for the Transgo HP kit to fix the issue. To solve this issue, you can get a shift kit that includes accumulator springs. Consequently, you will experience harsh shifting. If one of two springs of the accumulator gets broken, the accumulator fails to absorb the shock.
These accumulators absorb the shocks coming from the circuit. The transmission governor will go bad if one or two accumulator springs get broken in the transmission.ĭon’t know what actually the accumulators are? Well, they are actually a shifting modifying device that cushions the shifts within a transmission. And this chapter will break down everything. Now, it’s time to know what causes the transmission bad and how you can solve them. 3 Reasons Behind A Bad Transmission Governor & Their Solutionsįrom above, you learned about the signs of a bad transmission governor. You can also have trouble upshifting in the event of acceleration.Also, it will be a lot more difficult even when you try to downshift manually. You find downshifting a bit challenging when you try to slow down your car.The inside of the valve may get scored and hang up from the grit & clutch.
