Well after having the worst tranny luck in history, I am debating going with a straight cut planetary set. Has anyone done this? What are your opinions? I am having problems with the little bushing next to the gear going out. I have been through 5 bushings in 400 miles. I did the 4l80e swap to have a more reliable vehicle, but have had anything but reliable. I figured the straight cut gears would not let the gear push to the side and take the bushing out.
