Hello Everyone,
Just had a quick question to see what folks would recommend for flushing my SM420 transmission before I install it.
I drained it out and the fluid was pretty thick.
Also noticed there are two plugs, which I assume the one was the drain and the other a fill plug. They didn't seem to be that far apart and so I just want to make sure you only fill it with fluid until it pours out from the higher side plug or do you fill it some other way.
Lastly what type fluid and what viscosity should I use.
Thanks for the help.
Scott
