Vibration Off Throttle

Post by drift7one »

over the past week iI've noticed that Im starting to get a vibration/knock that I can feel through the floor board whenever Im coasting off the throttle. its consistently about the same, amd doesnt seem to be any faster or slower depending on vehicle speed. its most noticeable around 1500 RPM and coasting between 15-40 mph.

Might want to check the transmission mount on the firewall side. The rubber can wear out on them and then they stop dampening and it vibrates the car.

one of the first things I plan on doing after the holiday. had the trans rebuilt about a year ago, and the warranty will expire before the end of the year.
