I had my Ty in a trans shop to have the POS GM Serta trans' valve body reworked to firm things up and take care of a freewheeling problem on decel. After I picked it up I realized he has the WOT shift point way to high. 4900RPM for the 1-2 shift. I asked him to change the gov springs to drop that down and he gave me a story about it being a project. Take pressure readings blah blah blah. Told me it's a whole day job. Now, on my Camaro, I played with gov. springs to get the RPM upshift where I wanted it. I explained to him that I did that. He asked what trans it was and I told him a 700R. He then tells me the 4L60 is a completly different trans and you can't control shift points like that. I didn't just fall off the turnip truck and know the 4L60 was a rebadge till it went to the 4L60E.
My question is, why couldn't I just put a lighter spring kit in the gov? The shift points are to high at part throttle too. It won't go into OD till 48MPH and that should drop that down too. Opinions? Am I full of it thinking this?
