transmission

The single-wire system switches voltage (could be +5V, could be +12V - check to be sure) to the solenoid to control lockup. The solenoid is self-grounding. On a two-wire system, the supply voltage (probably +5V) is always present, and the PCM switches the ground.

If you want to use a '94 trans in your '96 truck, you'd need to use a relay. Connect the relay's coil terminals to the TCC connector of the wiring harness. Provide an adequate power source (need to check whether the '94 solenoid wants +12V or +5V) to the common terminal of the relay, and run the switched output of the relay (terminal #87 on an automotive-style relay) to the solenoid. When the PCM switches the TCC ground, the relay's coil will be energized, and will switch voltage to the TCC solenoid.

Now...there's a guy that knows his lockup.

Speaking of knowig his shit about transmissions, how about posting the TSB info you promised last week?

And the link to the aftermarket harness that would adapt the transmission for better towing performance.

Tom, How would i check the 94 trans for correct voltage and can i use any type automotive relay. Thank you, Harry

Get ahold of a '94 wiring diagram, and see if it feeds +5V or +12V to the solenoid. As for the relay, yes - your typical 30A 12V automotive relay from Radio Shack will be fine.

I have install a Mopar performance A-500 in an older truck. If the "production" transmissions are the same as the "performance" transmissions, and I think they are, then both the overdrive and lockup are 12V.

Yep, they would be. +12V sure makes life easier for the O.P.

In addition to what Tom said, there are some internal differences. Be careful not to mix up any of the internal parts. See:

Terrific info if you own an old musclecar and want to install a 518 in it.

But the original poster to which you promised info on a TSB had a 2002 Dakota with a 45RFE trans.

So you are full of shit as usual.
