Tranny question - G50

[Rick Lee]

My '87 Carrera drives fine, but something I just read on the Vertex site made me curious. They list a cause for tranny failure as "Down Shifting from 5th to 2nd or 4th to 1st or any downshift skipping a gear in order. This causes the dogteeth to engage forcefully and ultimately causing the transmission to pre-maturely fail." I frequently skip a gear when downshifting, so as to save one more shove on the clutch. I got 232k miles out of my BMW's first clutch and the original transmission is still going strong. My Carrera has 73k on it and drives perfectly. Am I really shortening the life of my tranny?

I have a '87 too and not agree with that concern about skipping a gear or two while down shifting. All I do is rev up the engine speed to match the gear like other manual trans.

Hello

The G50 has something like I would say a positve lock out mechanismen with makes it impossible to select two gears in one time.
( this could happen on old units )
Sure if the syncronisation has to break down more force they wear faster.
Skiping while Upshifting is no big problem.
