If you take not of the picture I attached - The 4 speed ( 23 spline ) that I am basing my post on has towed a camper, with a family of 4 and bikes on the roof - it was beat on heavily it's entire life. It had brass syncro's and they were in excellent condition and did not need to be replaced.



1) I stated nothing about syncros if you read my posting. Syncros with ATF I have no opinion, bearing wear on the other hand..

2) You are one example compared to the dozens of vehicles that sat in my work bay.

The roller bearings on the countershaft seem to really get hammered the most, ATF doesn't have great lubrication properties compared to gear oil or even motoroil.
