Can someone clarify-

Does the TC lockup normally come after OD engagement?? So you wire your factory GEN I to still activate the OD using the TPS and then use pressure or something else to engage the TC lockup?

I have a push button switch on the shifter for o/d and a floor(dimmer switch) switch for lockup.

 

My plan is to "piggy back" the OD with a 5 second delay timer for lock up. Later I plan to figure out how to control lock up in other gears. I have to keep it automatic for the wife.

 

For simplicity just use 2 pressure switches....
One for the OD and one for the TC.
Get them different pressures - I had 2 of the same pressure and it just acted 'funny' to me so I found a 47psi for the OD and an A/C tat's on at 45 and off at 37.

 

2 pressure switches? So this works off the governor pressures...

THe PATC kit? I was thinking of having the OD work off the TPS and then just have a delay- or pressure switch. Question is HOW??

I like having manual control over the two. When towing or up in steep country, it is handy to be able to go from 2nd to 2nd locked, to 3rd, to 3rd locked, to od.

 

Lock up in other than OD requires modifications to the transmission and valve body. My transmission will be built with that capability, I just don't know how to automatically control it yet. In the mean time my lock up will be controlled by a time delay relay piggy backed to the OD relay. I am also adding an adjustable pressure switch to go in the boost pressure line for a "part throttle" unlock before the TPS drops it out of over drive.
I will also have manual "cut out" switches.
