Listees:  Anyone have a feel for how often you should replace the
Synthetic MTL Redline fluid in a rebuilt 4 speed in a 90 GL?  Seems like
the old stuff(non synthetic)was to stay in there more or less for
life.  Any input greatly apreciated as we approach 20k on the Weddle
rebuild and I must say, it's working really well.
