I am in East TN, 444 miles from home. I have no reverse, it trys to go forward in neutral, it changes gears ok and seems to be ok in forward gears, The part time light flashes on and off when in 4 wd high. She has plenty of fluid, What are ya'lls thoughts? I have a great mechanic back in FL. I am thinking about driving it back for him to work on jt. Could this be a computer issue? What years computers are compatible with my 88 Laredo 4wd 4 liter automatic.? HELP Bill
