I had a problem finding a short shaft for a 700R-4, and finally found one. I thought I could put it in myself, because I really did not want to pay over 150 to get it installed , But I decided to let a shop do it. the trans came out a 91 camaro, the shaft, im not sure, but they said it would work on my 91 trans. I did buy it from a trans shop.. Well, now some shops tell me the shaft may not work, because of different count of splines , the guy at the trans shop, told me they were all the same ...(where I bought it from) This is the thing, can you tell buy looking at it?? I'm not sure, I'm not a trans expert I don't want to pay $167.00 to find out I need a different shaft. Some trans companys told my my front pump would not hold up to a truck Are they trying to SHAFT ME???????????????????
