I’m looking for a comprehensive wiring diagram for the 700R4 lockup. Any chance someone could provide a step-by-step guide to help with this installation?
Hey teresa31, I can help with that! You generally need to connect the lockup solenoid to the transmission and power it with a switch or vacuum signal. I’ll find a diagram for you!

A good way to start is to refer to the factory service manual. It should have a detailed diagram. Also, check out online forums for user-shared diagrams.
I’ve found the PDF versions online are super helpful. They usually give more details than just diagrams. Has anyone tried using those?
Definitely! Also, remember to double-check your connections to avoid locking issues later. Use a multimeter to make sure everything is wired correctly.

I once had a situation where I connected the wrong wires and ended up with a fried solenoid! Not fun. Can anyone share common mistakes to avoid?
Yikes! That’s a nightmare! Ensure you use the right gauge wire as well. Poor gauge can cause issues too!
For troubleshooting, if it doesn’t lock up, check your brake switch. If it’s stuck, the lockup won’t engage. Any other tricks?
Good point! I also suggest checking the torque converter itself. It can cause problems down the line.
Thanks for all the tips! This is turning into quite the informative thread. Don’t forget to share a wiring diagram once you finalize yours!
