    Re: 2001 Catera, slow to accelerate

    The car has new tires and everything is balanced. I think there is seal that secures the shift which may have gone bad. The gear lever does not vibrate during driving or braking, but when you hold the shift it rocks back and forth. In regards to the acceleration issue, the car is running fine and I think the roughness or slow accelerate they might be feeling could be from the new issue I found. There is a good leak in the back by the differential area, so I think the gear oil is low and the seal may need replacement. I'm not sure whar parts are needed for that and how hard it may be to replace it.

    Re: 2001 Catera, slow to accelerate

    One of the biggest problems with the 4L30-E is the range sensor on the side of the transmission (Where the gear selector is) gets all goobered up. It's a VERY common thing on the Isuzus and BMWs with the 4L60-E. Best thing to do is to take the sensor off and clean it... as seen here


    The range sensor being dirty causes all kinds of things, INCLUDING transmission failure.
