TCU pin assignment
After swapping out TCU in our 92 with 444 transmission, having problem with VSS1 not reading. Assuming I have a connection problem with the wiring connectors to the TCU or poorly soldered 28 pin dip, anyone know which positions are related to VSS1?
It is difficult to swap TCUs due to the location, trying to minimize time spent upside down...

Re: TCU pin assignment
I was under the impression that you weren't supposed to swap TCUs when doing the 4.44 swap. Or did you swap it out because it was bad?

Re: TCU pin assignment
Can you confirm the speed sensor still works?

Re: TCU pin assignment
That sounds like a great idea, how do I test it?

Re: TCU pin assignment
When I was testing out the 5spd after I first installed it, all of a sudden the speedometer quit. I ended up taking the sensor out of the 4EAT and using it in the 5spd.
Basically, do you have a working sensor you can borrow?
