jmead Posted August 1, 2003 Share Posted August 1, 2003 Alright...got my car running smoothly, now it turns out I've got a transmission problem. It turns out the vacuum line that connects to the manifold was loose, and leaking vacuum, causing the transmission to lurch at certain speeds depending on the throttle position. I re-attached the hose securely, and the car is much smoother, but it will still ocasionally lurch around during a shift. This is mainly at high speeds (45+). What more can be done to fix this? Is it possible the hose itself is leaking? What other parts could cause this to happen? I've read something about a "vacuum modulator" in the tranny. What does it do? I've got a 76 280z, auto tranny, stock. Thanks for any input Quote Link to comment Share on other sites More sharing options...
