Has anyone ever checked there fluid pressure at idle/wot with a 4L60 type transmission with a Transgo shift kit or a Hypertech (for example) programmer that increases pressure for firmer shifts?

Mine at idle is around 90 psi.Thats with some tuning and some different stuff upgraded in the trans.I'm pretty sure in stock form you should be right around 75 psi at idle. Traver

75-90psi idle, and I think 180-235 at WOT, somewhere around there.

Well I did some looking and found what my model 700R4 was at the factory settings. 65-75 idle, and 196-235 at full TV !! as it is a model YCM, on my build sheet. There are quite a few numbers within our transmissions. Idle is fairly consistent 65-85, but WOT is from 130 -245 psi, thats quite a range.
