I have a 99 wrangler 4.0 automatic. Having problems stalling. In the mornings when placing in reverse, backing up, coming to a stop then placing trans in drive, the motor stalls and dies. It will restart no problems, then will drive to stop sign, will stop, the engine stalls and dies, but will restart no problems. Noticed that trans wants to shift from 1st to 2nd,2nd to 1st with a mind of its own. The stalling happens mostly when cold. once in awhile it will stall when hot when stopped at stop sign. HELP!
