hiss from trans in reverse
Okay, something new today... I filled up the trans with fluid like it should be. Car shifts good but shift points are still off...I have not replaced the modulator valve yet.
So, when I put the car in reverse I hear a really high pich sound. I would guess a leak in a vacuum line some where? Very hard to describe the sound but its high pitch, stays at a constant frequency and only happens in reverse. Suggestions?
Setup: 1980, TH350 and 350ci... all stock
