91' 700r4 reverse drum probelm, help!
i know iam on the wrong forum here but running out of options, ok i have a 91 700r4 comes with a .095 reverse drum, i ordered a new reverse drum because the old one was too worn so the new one has a large sqaure hole. according to the atsg manuel the large sqaure hole drum will not work in a 91 700r4. only 93 and up ,and can retro fit early 82-87 but suposily the large sqaure hole drum will not work in late 87-92 acording to atsg manuel and i notice the 93 only has a added check ball for this large square hole drum. the place that sold me the drum said it will work in all 87 and up 700r4/4L60es. whos telling the truth here??
