New C4, lost forward gears after warm

ok cause i lose all forward when it warms up slightly, and i allways have reverse. Presure is still low in reverse 95 psi. So i dont know if its the pump or the valve body, im gonna get a pump from dynamic racing trans and i might send them my valve body to check it out.

Did you contact Jay at Broader yet, you are not giving him much of a chance to help you out.
I talked to the guys from Dynamic at a FFW meet some years ago and they did not impress me at that time, things may have changed.
Call Jay and see what he says but first you have to tear down and there should be something obvious wrong with pressure that low.

yeah i talked to jay yesterday, it seems like he is riding the fence. really not sure whats goin on. i just wanted a couple of opinons thats all.

That is understandable as it is a strange problem. Very hard to diagnose from a distance ... He has good products and i know the pressure he told me i'd have with his kit was spot on...A tear down will give you more to go on..

Pumps on C4s don't usually fail like that. Unless the stator support bolts back out.
My bet is that its a valve body problem. Pull the pan and take a look at it and if the bolts have loosened up, tighten them back to specs. If you don't see any apparent problem then pull it out and see if the regulator valve is stuck. Call Jay and see what he thinks of you pulling it apart to locate problems. He will probably want you to send it back so he can find out what went wrong. They are good people, let them do their job.
