OD and convertor manual control?

326 Views 3 Replies 2 Participants Last post by  alanack6795
Is there a way to manually control when the OD and convertor engage and disengage? I installed a switch and ran the wire to keep the convertor locked up but I'm looking to control the OD and convertor completely separate from each other to be able to tow at the perfect RPM's....

Toggle switch for lock up, toggle switch for OD
Valve body needs to be modified to allow lock up in 2nd gear.

I've seen guys use a 3 pole switch the "force lock up" disable it, or let the pcm decide
