Here is my problem ..... need advice!!!!! HELP Hi
I have a C5 vette 2003 just finished Auto conversion went to 4l60E from T56
I got little used newly opened built 4l60E whith Vacuum valvebody (not full manual valvebody though)
I used Auto transmission harness from another car and NEW RPM jumper harness connected between it and PCM
Reflashed the PCM used stock Corvette C5 Auto Tune as a compare used HPT
but there is some bug in the system it seems.
when i put the car in D is goes straight to 4th gear
3rd straight to 3rd
2nd is straight to 2nd
and 1st gear it is like it is stuck, maby in two gears or something like that doesnt turn wheel , just like itīs on brake
and when i manual press the the solenoids in the HPT the 1-2 solenoid rattles like it getting pulse in stead of just one click
the trans was opened up an the valvebody was taken out after this and all the solenoids are ok and works right on the table but itīl like itsīgetting wrong signals from the pcm or harness.
I went over all the jumper harness connections and they are all right connected it seems.
do you guys have any suggestion on what could be happening here
thanks
