Built 4L60E problems Opinions wanted.
Ok, I had my 4l60e built by a shop in my state. They did clutches, sunshell, billet servo, and a few other things. I believe the only parts not altered were the valve body, planetaries, and pump. They also gave me a 3000 stall with this. The brand was ACC. I paid about $1200 for everything, and I did the removing and installing. The first time I put the new transmission in the case cracked right under the governer. I took it back to the shop with a case I found and had the guts swapped. We installed it again. It ran ok at normal driving. If you get to a roll (30+), and put it at WOT the car just peggs the limiter. After about 3 weeks of being in the car I lose the ability to use 3rd and 4th. That was my original problem on my stock transmission. What could be my problem? My car had been tuned before I bought it, but I do not know who did it. The shop wants me to bring the entire car to them. The problem with that is the shop is clear on the other side of the state. What would you do in my situation. After gas costs and trips made I've put a little over 2k into this project. What should I do?
