Transmission Control Module wiring?

92 Grand Voyager, 3.3L. I think the module I'm looking at is the
transmission control module. It's a square box in the engine compartment on
the firewall, passenger side next to 2 relays. I need a wiring diagram for
it. Is it the transmission control module?

Yes, that is the TCM. I have the schematics in the 1991 FSM which should be
the same. What is it that you are trying to troubleshoot? Have you pulled
the TCM trouble codes to help guide you?

 

I posted a few days ago about noise on a CB radio. It's so bad on one
channel that I can't hear anything else. The TCM is what I traced it to. I
found 2 wires that are 12V sources. One is always on, the other is on with
the ignition switch. I have been able to suppress the noise with very small
capacitors but I want to make sure I'm not suppressing any AC control
signals. Can you email me a copy of the schematic or what the wires coming
out go to?

Thanks,

Chris

The 2 pins are 11, which is blue and 56, which is red/white. The capacitors
are either a 150pf on 11 or 220pf on 56. It takes the noise from an S-meter
reading of 8 down below 1.

I'll e-mail you the two scans shortly.
