T&T: Synthetic Transmission fluid?

[Gary Brobst]

Keith,

Changing the fluid is no problem if you put a tee with a plug in the return
line hose.  Take just a few minutes to do the job.

With a change at the recommended 100 hours, you are not changing oil any more
often than in a car.  At an average speed of 30 mph and changing oil every
3000 miles works out to 100 hrs of driving time.  Same as for boat.
