No acceleration in gear 98 Chevy tracker - 1998 Chevrolet Tracker

Cam bearings installed wrong = most likely.

You need to replace your torque converter, your Transmission does not move/turn in any way while in park the only part that does is the torque converter. I would also get a full fluid change when that is done as well.

Transmission pump starting to fail. Funny you mentioned "power steering PUMP" although its not really funny as in HA HA. :(

The owners manual says to use the overdrive gear under normal conditions and when pulling a trailer.You are suppose to drop down on gears only when going up a incline ( Hill ) that is causing you to accelerate drastically.

Do you have the stye that you have to manualy turn on each wheel to engage the axles...? If not you may have the pinion gear broke in the front. Will be pretty expensive if that be the case......

Sounds like a bad countershaft bearing. The trans will need removed and disassembled to fix it.

unscrew them, 1 at a time ,set the gap to spec, screw back in and set to 25ft/lbs torque.
