Tranny problem, HELP!!!

[silver01]

Well I just got done doing the shift kit and installing 2 and 4 gear servos. Problem I am having is that if I put it on D the truck takes off on 2nd gear and 4 gear wont come in. If I manually put it in 1st it works and I can shift to 2 and 3 but no 4th either. If i put it in 1st manually and WOT it when I shift to 2nd it will shift, no matter what the rpms are, it wont wideout the 1st gear. It will wideout 2-3. I am lost with this. Ialready checked the fuse on the driver side and its fine, I also checked for voltage at the tranny plug on the 2 pink wires, I have voltage. Any thoughts on what to do next.

Thanks

Make sure the 4th apply piston is not in backwards as far as the 4th gear problem goes. With the other stuff you might have an issue with the shift kit install but someone else can answer that.

Yeah, check the 4th piston. Make sure it plunges without much force. Some people who have done their own shift kits mess up on that...

Yeah, and I am with Nathan--the valve body has been messed with. Take it back out and reinstall it all. I know, it will suck, but you gotta do it....
