I wondered if any of you could help me out. I have an 85 T/A and am putting the 140 speedo out of an 87 in my car. I talked to the parts store and they said that there are 3 different ones and I would have to look at my old one to know. Well suprise I dont have the old one. I have the wiring and buffer box, but need to know what sensor to use. It is a 700r4. I know that they are different between manual or automatic, but what is the other one? When I talked to them they said that they had 3 letter numbers and they started with d I believe. If anyone could help that would be great.
