i had my entire trans rebuilt including the trans case. ive had multiple mechanics looks at my truck and no one can seem to fix the problem. because of it bouncing between 2 and all wheel drive im about to buy my 4th set of tires in 5 years. only thing left to try is the switch on the dash, but ive been quoted almost 2000 to change that. tires are a cheaper way to go. this truck has cost me nothing but money from day 1.ive never had so many problems with a ford before and thats all ive ever owned.
