that was the code i got. i replaced the a & b solenoid and tcc solenoid w/ no solution. i have a buddy that has a friend that has a scanner that is capable of doing a tranny scan. i will have answeres tommorow if all works out. i have a wait4metune, should i put it back to stock or leave the tune in. w/ the tune i get the ses light because i need to do the crank relearn. regardless i'm still going to do the servos and all that just so my tranny will last longer. i'm keeping this truck 4ever.

I can put a kit together for you. Have you scanned this vehicle? I'm kinda curious if the computer is commanding 1st or 4th? There should be some data that you can read via scan tool. You need to look to see if it is firing the shift solenoids. In first gear you should have both shift solenoids on. 2nd gear one of the two will shut off. In 3rd the other will shut off -no solenoids on at this point. To complete 4th the solenoid that first shuts off to complete 2nd should come back on. If this is not happening you have an electrical problem. Whether it be wiring, computer or solenoid failure. If you are seeing the commands it is probably a hydralic failure such as what you want to do with the parts that we are talking about. If you would like to give me a call tomorrow we can discuss this over the phone. It may also be a good idea to drop the pan on your truck to see if it is clean with good looking fluid. If it doesn't look good you should probably consider ordering a trans. Give me a call, Vince.

when this first happened i dropped the pan and changed the fluid and filter. the bootom of the pan was covered in soot. it was a real fine powder. i'm guessing from when the tranny was rebuilt. tonight my buddy w/ the scanner came over w/out it thinking he could tell by driving it. long story short he needed the scanner. he did tell me the electronic syncro (i think that is what it is) on the side was not kicking anything on. he had me shift it in and out of park and drive , he said he could not feel the relay kick in. it would not kick in theough if it is in limp mode though. he says the way it is shift though he thinks its a vacuum problem wich would come back to the parts in the valve bodyi.e. check *****, separator plate, ect. if i'm not mistaken any way. he going to come back tommorrow. to run the scan though.
