Hey oilburners, I have a 86 6.9 with a c6 tranny. I replaced the ip with one from R&D about a week ago and ever since then my truck will not shift right. The pump is from a 7.3 idi I'm pretty sure. At first it would shift from 1st and skip 2nd gear and go to 3rd. Now it will not shift out of 3rd gear when it is in D. If I manually shift it into 1 it acts like it is in neutral and if I shift it into 2 it works fine. I played around with the VRV and it didnt really help much. I then replaced the VRV with a yellow one because that what I believe to be the right color for this ip. Now after driving it the tranny is leaking too. Any help would be appreciated. It shifted perfectly before I installed the ip.
