I have a TH350 in my camaro. When i put the shifter to Reverse she moves just fine, then all below that dont work, when i put it into the 1/2/3 slots it just revs, it acts like it wants to move just for a second in the lowest slot (1) but it doesnt. I checked the fluid its fine. the linkage is ok to, or reverse would be in a wrong spot. any ideas? Its got a B&M street or strip shift kit in it.

I took the car out once, she shifted perfect, nice hard shift, real quick. Then the next day i put her into gear and she revs...im confused.

 

bad pump,bad converter,or direct cluches are smoked

 

the vacuum modulator??? try that first.
