I recently converted to Jeepizm, an 86 cherokee 4whl dr, 2 dr, V-6 2.8 liter. Transmission shifts beautiful from 1st to 2nd but does not move on to 3rd. Also, no reverse. I have serviced it myself and found a very small amount of metal on filter and some metalic fuzz on the magnet. Could this be an adjustment somewhere or is it time to pull the old gal. If so, can I take it to a reputable transmission shop to be rebuilt? If thats the case what is a normal price to walk a transmission in? Odometer reads 145,000 :?: :?:
