Hi I have a 700r4 in my chevelle, and I am kind of confused. The guy I bought it from had it in a firebird with 500 hp and he had it built from a local shop and ran it with no problem. Now here is where i am confused I have not wired in a switch and the tranny locks up in second gear and 3 and 4 while driving also it has a manual valve body. The car will die when i and going to park with my shiftier I am using a hammer shiftier from B&M and you have to go into overdrive to put it in park. Why does it lock up in 4 and not moving???? also It came with a tci lock up converter. Any help would be helpful oh I forgot he could not give me any real info on it he is the type of guy that says here is the cash go build this for me. I have put over 4000 miles on it while on vacation then the Hot Rod Power Tour. Now that I am driving around town with it, it is a pain in the butt.
