From Redlines literature regarding MT-90 - "good shift ability, and
synchro compatability and extra gear protection."
When I got my 88 GL, I had shifting problems from day one.
On tear down of the tranny, my tranny fluid was filled with really fine
brass particles to the point of appearing golden in color. According to
my repairman, this was a synchro problem.
I had a noisy tranny - it would "sing" going down the highway ... a lot
like big trucks that have a worn ring and pinion gear. When my tranny
was torn down, there was an abnormal wear pattern on the ring and pinion
that was clearly displayed. Source of the singing.
After a considerable discussion with the mechanic, I opted to have the
synchro components repaired, but not to replace the ring and pinion
gears as it was the experienced opinion of the mechanic that the repair
that was done, combined with my choice of new gear oil, would resolve
the biggest part of the ring and pinion problem.
So, I opted for what appeared to me as the best of the best - both
from the Redline literature and the historical perspective as gleaned
from "The List". I put in the Redline MT-90 to deal with any future
"shift ability, and synchro compatability and extra gear protection"
issues.
I have not regretted it.
One final point. Somewhere, I have read there is a problem with some
gear lubes causing problems with the synchros in these manual
transmissions. The collected positive experiences of the members of
this list had a strong impact so far as my going to the MT-90.
