Dave,
I'm gonna go ahead and gear this question towards you.
I just finished up putting my tranny back together lastnight and tested it out. The transmission sounds normal, no whining or metal sounds.
I have Forward and Reverse.
I only seem to have 2nd gear, no matter what position the gear selector is in.
No codes came on until 15 minutes of driving while I was changing the gear selector to see if I could get the car to shift into 3rd. Once the codes did show up, here is what I got.
0742 - TCC System Stuck on. I did install the new Sonnax valve with the teflon seal, but the converter didn't stick until the tranny temp reached 225* and I was 30 minutes into the drive.
0756 - 2-3 shift solenoid valve - Performance (No First or Second Gear)
I think this is the problem. I installed 2 new shift solenoids in the valve body. I believe they are the 1-2 & 2-3 shift solenoids. But at the same time, I changed the wiring harness as well because on of the retainer clips broke, so I used one of my old harnesses.
So I think my problem is in the internal wiring harness that I changed. Because 1, of the 2-3 shift solenoid issue and 2, my performance shift light cuts off when I put the car in 4th or 3rd gear, but comes on when the car is in Neutral or Park....weird.
Dave, Do you have any other suggestions or things I can try? Is there any pinouts on the big tranny plug I can ohm out or check? Is my thinking right with the 2-3 shift solenoid?
