tranny wont shift
okay so here's the deal ! once again I'm having issues, this truck is hell ! i just did a 700r4 swap into my truck. i put a B&M shift kit in it, corvette servo, a deeper pan, lock-up controls and a secondary transmission oil cooler. I filled it up the fluid and put it in reverse and got no response from the tranny at all! same with all of the other gears. i have verified that the pump is working as the cooler lines have fluid in them. just wondering if anyone could shine some light on what is going on here ! my guess was that the filter isn't sealing properly (or is cracked) and there is fluid movement but not enough to make the truck move (like drinking through a straw with a crack in it). just wanted to hear any advice before having to pull the pan off again. thanks !

Re: tranny wont shift
If you put the filter on and filled the pan, crank it back up and hold the brake and shift it through the gears. It takes a minute or so to start going into gear when you've drained the fluid.

Re: tranny wont shift
It should only take a minute to start going into gear. When you pulled a line to verify fluid movement, did it spray pretty good?

Re: tranny wont shift
History on the unit??
Did you change the pressure regulator spring or Boost valves? If the snap ring didn't get seated. The Boost valves, Reg. spring & Reg. valve will be sitting in the bottom of the pan ![]() |

Re: tranny wont shift
well.... i took the pan off today actually and you will never guess what was laying in the bottom of it.... the boost valve.. i had a pretty good "awweee for f*ck!" moment haha but it could have been worse, i just have to make sure the lock ring is actually in this time .... kind of embarrassing really...
