tunning the shift points on rebuilt e4od
Hey everyone I am new to this site and being a powerstroke owner. I purchased my 97 f-250 with a bad tranny and that was all I knew about it. I had my local shop stick in a stock rebuilt tranny and everything worked good except the shift points seem to be all over the place. I asked them about adjusting the shifting but their computer would not read anything on the truck. I was wondering if this was a sign of aftermarket programming/chip? It works fine if I manually shift the tranny, but I was wondering if there was a way to set the shift points.
Thanks in advance for any advice!
