    Anyone use a B&M 70244 Torque Converter Lockup Kit? or the Painless 60110?

    I used the TCI lockup kit

    The Painless looks very similar to the TCI though the actual vacuum switch is different.

    I wish it would dry up so I can get out and give it a trial run.

    Well, I've got something wired wrong. Since it is a ground wire, I'm afraid I've gotten something out of sorts. I'm going to try something different.

    How do you have it wired?

    I teed off the cruise brake switched side. When braking, the switch cuts 12+ to the trans and the delay switch. One leg goes to the transmission. The other leg goes to the delay switch 12+ side. Into the trans, out the other trans for the ground side to the vacuum switch. From the vacuum switch to the to the switched side of the delay box.

    I think my problem is the ground side isn't grounded yet and it won't trigger the delay to come on. I'm going to try to wire the delay switch inline to the ground switch since I'm thinking it will be 12+ until it actually grounds.

    I might have to draw a diagram to help me understand it myself.

    For sure you need ground or it won’t lockup

    Yep, know that but I think what is happening is the 12V+ in to the delay switch is backfeeding into the TC solenoid so that there is no ground.

    Here's a diagram.


    I'm going to try this arrangement to see if it solves the problem, which I see as having 12V on both sides of the Delay Switch input. I'm just not sure if it will work due to the circuit grounding when the vacuum switch closes and essentially bypassing the Delay Switch since it completes the circuit. I'm not an electrical engineer so I'm winging it and relying on fuses to save my rear.

    OK, after seeing it drawn out, I think I need to do it quite a bit differently. I don't want any ground in the circuit to the transmission solenoid until all the other external conditions are met. This diagram seems to make more sense to me.

    Power to the brake switch cruise side unless braking. Power the vacuum switch unless low vacuum condition. Power to the Delay Switch unless braking or low vacuum. Power to the TC solenoid 5 seconds after no brakes and high vacuum. Transmission always grounded on the output side. Boy, the color of my wiring is going to be all shot to heck and back. LOL

    Well, that worked better and but not what I expected. The delay starts any time it has enough vacuum and the brakes aren't on. So, it still drops into 4th, immediately locks the converter because the delay has already expired. Maybe I need the ground of the delay switch wired to the 12v+ going to the transmission. That way I can't complete the circuit until 4th gear grounds it?

    I'm not sure this will ever fire because the ground doesn't happen until the delay expires but the delay never starts because it isn't grounded. I'm confused I think.
