I did a T-5 to a C-4 swap a few weeks ago. The c-4 has a reverse manual valve body with trans brake and a 2500 stall. Evertyhing was fine till last week where i was sitting at a light and put it in nuetral to rev it up..i put it in first when the light turned green and nothing...tried second..nothing...third nothing....i decided to try reverse and it works fine. I'm totally lost on what could have happened...the trans is coming out tomaro is there anywhere special i should start looking for the prob at?

 

did a shop build this for you?

 

Not sure, i got the trans off of a friend that is parting out his car.
