installed the megashifter and now the car bogs down when it shifts

i just got a megashifter out of the junk yard ( all of it minus the switch ). the plug on the tranny had the wires re-routed. one was just cut. one whet to a switch under the steering column ( i believe it was the brakes or something ) . And one that was converted to a ground. now when i put the car in OD it trys to stall when it shifts out of 1st 2nd and 3rd. i have adjusted the cable a billion times. i have a problem with that also but i want to fix the freaking shifting first. also sometimes if im driving slowly and it gets to 3rd the rpm's will drop to about 800, however if i shift it myself it goes decent. i need some help and i need it quick im afraid to drive m car right now

If his TC is locked will it do that? maybe those wires has something to do with it.
