Here is the brief version: When I restored my own car #3231 3 years ago, I refurbished and relocated the shift computer from the side of the trans into a project box. It's worked flawlessly since then. I am currently trying to finish up restoring #6597 for a family member. I tried doing the same restoration (based on hershey's computer updates and fixes) and moving the boards to a project box. The damn thing has been stuck in third and won't shift which is a clear indication that power is not getting to the solenoids. In trying to troubleshoot, I tried moving my shift computer to the project car and see if that solves the problem, of course it did not. However, now my computer no longer works even in my car! My car is stuck in third as well. I found some hand drawn schematics on dmctalk.com and tried metering to make sure power was getting to the boards and whatnot (also checked the fuse in each car) but i'm not certian these schematics are accurate. Compounding the problem, I've misplaced the wiring diagram I drew when I relocated my own shift computer 3 years ago so It's not really a matter of matching up the connector I made on my own car with this one. I need help from the community. First off, I think I want to start by verifying that the transmission itself is ok and the solenoids are ok. Is there a particular set of wires I can just send 12 volts down to activate the solenoids directly to see if it will shift? I know power to both solenoids is first, drop the first solenoid is 2nd and no power is 3rd. The cables from the shift computer don't seem to go directly to the solenoids. The go to a big old connector on the firewall first. What is inside that block? resistors? relays? Assuming I can do that and verify shift functionality, is there a decent color wiring diagram or schematic so I can see exactly how the whole circuit works and hopefully put the computer on a bench and test with a meter. I can see that there are 2 wires (red and gray) that supply 12 volts. There is a peach colored wire, 2 wires that appear white, a black, which I believe to be ground, a blue one, and a green one. Not too long ago someone posted a video where they had the whole thing on a bench and was able to show the solenoids moving. Maybe this person drew a diagram? Sorry for making this so long, I am just frustrated and hope I don't have two fried computers on my hands.
