1st check from ECM (still plugged in) to Solenoid (unplugged). (tranny plug still connected)
2nd check from ECM (still plugged in) to Wiring harness Trans Plug (unplugged).
3rd check from Transmission connector (definitely unplugged) to Solenoid (unplugged).
All 3 good on the green wire, 1 and 3 bad on the yellow wire, 2 was good on yellow.
is it possible they told you it was new but its just the original?
This is confusing. I'm not sure if you mean the person who built the trans? Just to clarify, I built the trans with my own two hands. I bled, sweat, and cursed it into life. The only help I had at all was when a buddy helped me unload the core out of the trunk of the car I had to use to go get it.
If maybe, you mean the company that sold it, it was pretty obviously new manufacture when I unbagged it. In retrospect, I think I bought a unit constructed with the cheapest possible wire they could get, that clearly can't stand up to a 2 year soak in ATF.
i also agree with schurkey, if intermittent continuity to B solenoid, you would have 2nd and 3rd (electrically). if there was a transgo HD2 kit installed then you could have manual 1st with the main connector unplugged.....
I have no explanation. But I do have a little more information. The trans was built with Sonnax parts right to the spec of their level 2 build, with one exception. I orginally installed the billet 2nd gear servo used in their level 3 build, but it was too harsh, and it's been swapped out for a 'vette servo.
So yes on the shift kit, but it's Sonnax.
The only other oddities are,
A. I used a core from a 94. There are minor differences, but very minor, and none that matter from outside the trans.
B. The core I used was a 4WD. I just bought a new output shaft and re-used my output housing. I did this cause I really like the aluminum dust cover, and really hate the stamped steel one on the 2wd models.
Just had a thought about the weird shift pattern. If the cracked insulation allowed the wires to connect somehow. You could only have 1st or 3rd. Solenoid A would power both A and B, and if A was off, then they're both off? Weird as all get out, and totally improbable, but it's the best I've got.
