Transgo Shift Kit for 4L80e

[rcapone]

I have a level 4 FLT 4l80e in my truck now and before I ordered it, asked Chuck if I could get this shift kit installed as well - he told me they don't use it and use (I think he said high performance valve bodies) instead. HOWEVER, this trans shifts just like a factory trans. and I must say I'm unhappy with the extremely smooth shifting. The 60 I pulled out had the Transgo already installed and it was really awesome and firm shifting. I was just wondering if anyone had input or experience with this shift kit on the 80e. Thanks.

I would think you should be able to tweak the tune for some of it. I have been working on my car and finally got it so when your in town its pretty smooth and soft, but when you get on it .....its pretty firm once you get past quarter throttle. I did have it set up for firm shifts for town driving and I didn't like that. Shifting from reverse to drive or whatever it was just to harsh so I lightened it up for anything up to 1/4 throttle.

Most of your smooth shifting is from the stall converter. From your logs the transmission is shifting very quick just as a normal one with a shift kit would. Down the road once you end up getting the converter tightened up your transmission will have alot more of a firm shift feel. Some of the guys on here with higher stall converters such as you have might step in to also point out the same thing. Because of the stall speed your converter isn't even beginning to tighten up until well past 3300rpm which would make any shift below about 4000rpm feel soft because the converter is still in the stall range and absorbing the hit.
