southernjustice76 Posted December 18, 2006 Posted December 18, 2006 Any help diagnosing would be greatly appreciated. I jumped in the truck the other day and it wouldnt shift out of 1st gear. Eventually the transmission would shift but it shifts under high rpm's. Never had a problem with the tranny before. Fluid is clear with no burn and fluid is not foamy to indicate complete tranny failure. Was wondering what it could be? (shift band, linkage, solenoid, computer)
Twisty Posted December 18, 2006 Posted December 18, 2006 mine is doing the same thing. ive put in a new TCU, and changed both fuses. I'm thinking it might be the TPS, or the solenoids. There is an AW4 manual available on pirate that you could check out...its a PDF file and has LOTS of good info. let me know if you solve the problem. I will be working on mine in the next few days, and will post up if i find anything.
Bounty Hunter Posted December 19, 2006 Posted December 19, 2006 I recommend having the TPS checked and adjusted using a computer hooked through the diagnostic port on the pass. side fenderwell. YOu can remove the fuse to the TCU (under the glove box) and shift the AW4 manually.
southernjustice76 Posted December 20, 2006 Author Posted December 20, 2006 Where is the tps and tcu for the transmission? I'm thinking its the tps that went bad. Is there a fuse in the cab for the tranny? How do you check the tps? Any ideas of where I would find a replacement?
Twisty Posted December 21, 2006 Posted December 21, 2006 the tps is on the throttle body. where i have no idea. can somone answer that for me??? the TCU is a small gray box about the size of 3 dvd cases stacked ontop of eachother. its under the dash on the passenger side. there is an inline fuse there, and a fuse in the fuse pannel
southernjustice76 Posted December 21, 2006 Author Posted December 21, 2006 I found the tcu with the inline 10 amp fuse. Fuse was ok as well as the fuse in the panel. don't know what the tps looks like on the throttle body? Theres a seperate cable coming off the throttle cable that seems to go into another cable that goes into the cab. Anyone know what the tps looks like and how to check adjustment. Pics would be great.
JOMJ87 Posted December 21, 2006 Posted December 21, 2006 Its on the TB and I believe its on the side closest to the cab. it has wires going in it Cole
southernjustice76 Posted December 21, 2006 Author Posted December 21, 2006 Thats what it was the tps. Put the new one in and it runs fine! Thanks!
