I just purchased it and put it on my truck and WOW! Big difference! No more 6th gear with the torque converter locked when only going 35 mph! A lot firmer shifting, no hunting around for gears! Money well spent!
Ya they raise it to 175psi from 160(stock)I have this OD tune as well and like it alot. However, as of late, I have heard some rumours that it raises the line pressure past the safe operating perameters of the tranny. Can anyone clarify this please. Thanks
