2002 Isuzu Trooper 3.5l 4L30E Transmission Fixed well almost

Low band adjustment on Fiona to attempt to fix a slipping issue. The vehicle had no 1st or 2nd gears and with the expert advice of 4L30E Guru on Planetisuzoo I was able to get this issue repaired 100 percent but after driving the vehicle several hundred miles the band started to slip. At this point the only other option is a replacement or rebuild.
