sooo im on my 5th 48re ...just wondering if anyone else is having the sam problem

Ya I put a VB in my truck that Dusty sent me that had a casting problem in it and when the line pressure was turned up it wouldnt shift til like 2800 in 1st,2nd and fine in 3rd and 4th but he ended up replacing my VB for free. I have plowed snow, pulled 20k trailers, drag raced and sled pulled and no problems

hey revo diesel what was your line pressures
