So I recently bought a LS400. The transmission completely broke down. Burnt fluid and internal parts completely burnt and broken. Paid $2000 for a complete new rebuild. For some reason my gears are not shifting properly. While driving I ease of the accelerator and the car jerks. Also from neutral shifting to drive the car jerks really hard. Also when in reverse the car doesn't quite move and I have to push the accelerator quite a bit to have the car finally start moving in reverse. Anyone help me to know what the problem is and bout how much it would run me?
