Anyone know about the 4L60E 1-2 accumulator?

Did you have any trouble installing the new one? I’m handy but transmissions are a different story!

22

If you hear a clunk when shifting, it might be worth dropping the pan and inspecting the accumulator spring as well. It can fatigue and cause problems.

23

That sounds like a solid theory! I noticed clunking too, could the 1-2 accumulator really be the culprit?

24

Definitely! That clunk can often arise from excess play in the accumulator. Just be careful with the pan seals when reinstalling.

Good to know! I always dread messing with pan seals. They can be tricky!

I faced the same issue. Try checking the fluid levels too; sometimes, low fluid can create harsh shifts as well.

That’s good advice! I often forget to look at fluid levels first. It’s an easy fix if that’s the problem.

Has anyone tried adding a shift kit to help with harsh shifts? I’m debating whether to go that route.

29

I’ve heard mixed reviews. Some people say it improves performance, while others have had issues.

I installed a shift kit and now my 1-2 shifts are much smoother, but my friends joke that my car shifts like a race car now – it’s quite lively.

31

Haha, nothing like a race car feel! Just make sure you don’t start drag racing on the freeway!

32

Anyone else notice that sometimes the accumulator issues seem to come and go? It’s almost like it has a mind of its own!

33

So true! It’s like a moody cat that only behaves sometimes. What gives?

34

I’ve done some upgrades on my 4L60E’s 1-2 accumulator. I replaced it with a billet aluminum one for better durability. Noticed a significant performance boost during shifts!

35

That’s awesome, shelby58! I was considering a similar upgrade. Is the installation process complicated?

36

The installation is pretty straightforward, tammy21. Just make sure you have the right tools and follow a guide! It took me about an hour.

37

Thanks, carlrosario! Any specific brands you recommend for the accumulator?

38

I’ve heard great things about Sonnax and TransGo, simsmaria. They both make high-quality accumulators that improve shift feel and responsiveness.

Cool! Does anyone know if these are compatible with stock setups?
