No reverse,but all foward gears still work.
Crankshaft rod and pin failed. Nlm
We are currently having a pressure build-up in the transmission causing the fluid to push throught the dip-stick cap. We are in the process of getting the transmission re-built and are wanting to know if this is a common problem with this make and model or if there is possible a hidden warranty we should find out about.
Half the time this transmission will not, will not go into reverse ! ! ! ! ! ! ! ! ! ! I had gm look at it tell it finally went out of warranty. I think gm stopped using this t-5 after '94'. Figures. Well, thanks for listening and that takes care of that ! !
Cosidering my long experience with the gm product line I am disappointed with the early failures of these components. I specificly contacted gm about the transmission failure received very little support or satisfaction from them.
Abs brakes; brakes fail intermittently on one occasion brakes locked.tt consumer states on four occasions he would hit the brakes hards and the right frot tire locked up, on dry pavement, consumer also states transmission seems to be slipping going forn 1st gear to 2nd when the vehicle is warming up.
When raining the ABS brakes lock up and will not stop the truck. Tt consumer states that after the truck sits in rain overnight or for a couple of hours, the ABS will lock, problem occurs with little pressure applied and clears up after first couple miles of the trip, dealer has made several attempts to correct problem, however has been unsuccessful. Alternator was replaced. There is a noise in the throw out bearing.
