I purchased A 700r4 that has to be shifted manually. My I.D. tag reads THF 520737 . Can someone tell me the year trans I have. The trans rebuilder has wrote on the trans in yellow paint saying -Griffin Trans

I am going to install a hammer shifter. I also need to know about the elec. switch on the left side of the case , one wire is grounded to the case ,the other is short with a wire connector on it. My question is when do I energize this switch. Also to the rear of the case on the same side is what I quess is the speed-o-meter drive. Another question? How do I hook up a speed-o. And how is it calibrated.
