the truck is a 2004,the older body style. has a 4.2 automatic 4x4 transmission. i recently replace the transmission. and this is the problem iv got now, when i get up to 10mph the overdrive light blinks, when i get up to 60mph its like the transmission shifts to neutral, after slowing down to around 45mph its like the transmission kick back in to drive. and when speeding back up to around 60 mph it does it again. when you come to a complete stop it does the same thing and the overdrive light never stops blinking untill you shut the truck off. i took it a near by machanic and he says that the truck has a wireing problem but i went out there to see what he has done to it and he took the speed censor of the old transmission and put it on the new one and the censore by the gear shifter on the transmission was also switch. could it be a wireing problem or a censor? if anyone has any ideas, it would be very helpful. one more question, could the transmission still be bad? when he hooked up the computer to it, he said its not reading anything.

  Take it to a transmission shop a let a tech who knows what to look for in the serial data concerning the trans. I suspect you have a trans problem developing.
  I sure wish RepairPal had spell check in their answer section!

  It is time to use that 90 day warranty.

  it is a used trans, it came out of a junkyard. the id plate on the side of the trans is missing but it has a 90 day warranty, the guy said it had 60000 miles on it. and the truck that it came out of was wrecked but i never seen the truck and the mechanic that is working on the truck is the one that got it for me. hes had it for over a month, im starting to feel that im getting scammed. any ideas or suggestions?

  junkyard trans are always a problem. you need to get your old one back and take it to a trans shop and have them give you a bid to bench it for you. it may be better than having them do the whole job and much cheaper.
  get your money back for the junkyard one. remember, they are in the junkyard because they are junk!!

  The political correct term is SALVAGE not JUNK yard. There is legit SALVAGE yard sales. Not every SALVAGE yard sells junk.
