Standard trans swapped to 700R. Help!!

[OrangeCrush]

I purchased a 2006 TJ with a 700R with a Novak shifter. Need to get the reverse lights working.

What to do? There are two wires coming out of the side of the 700R trans that I am assuming is a reverse solenoid? I can't locate any wires that were attached to the stock shifter. Can I find the stock wires and attach them to the wires on the trans and it will magically work? The clutch slave and clutch pedal have been removed so I didn't even notice it was a manual when I purchased it. Thanks for any help you could offer!

Sorry, I know nothing about the 700R. But I wouldn't assume anything, and I wouldn't expect magic. That could also be wires for a neutral safety switch.

This begs some questions. Does the speedometer work, and if so, how? What engine does this Jeep have?

If it's a 700R doesn't that make it a automatic?

I'd verify that those wires are for reverse prior to hooking them up to anything. And just to clarify, are you trying to get your reverse lights working or something else? What Novak shifter are you referring to?

Those wires you see are most likely for the TCC. If you want backup lights, use something like this:

That’s a GM TH700-R4 automatic transmission with overdrive. As noted above, the wires are likely for a lockup torque converter, and the reverse lights can be controlled with a switch on the shifter.

Yes the speedo works. It is mechanical from the stock transfer case. Stock 4.0 engine.

It’s a Novak gate shifter. Yes, trying to get reverse lights.

Yes it’s an automatic. They took out the manual. Didn’t realize it started life as a manual before I bought it. No clutch pedal and never thought to check otherwise.

Controlled automatically or manually?

The wires are definitely for the lockup torque converter. It's been decades since I was last in one of those but I recall there being multiple permutations of switches and solenoids so that there wasn't any one way to wire up lockup - some were self-grounding, others needed both 12V and ground. Only way to be sure is to pull the pan and trace the wiring, it should run through some combination of one or two pressure switches (so that it only locks up in either 4th, or 3rd and 4th) and the solenoid itself. You also need to run that wire through a brake switch that opens the circuit so that the converter unlocks under braking, and a vacuum switch so that the converter unlocks under heavy throttle. Unless the PO had the transmission built specifically not to use lockup, not having lockup enabled is a great way to cook a 700.

As far as the reverse switch, that has to go on the shift linkage somewhere, and should also be the same switch/linkage that acts as the neutral safety switch. The kit Daryl linked above is probably the best bet.
