The shop owner who installed the TIICO in mine changes his every 2 years.
His primary vehicle is used as a daily driver and offroad extensively in
summer, and periodically in winter. I'm going with the 2 year change myself.
I've also go the MTL Redline Syn in mine. $30.00 or so every 2 years doesn't
seem like much of an expense for the investment.

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.
