This is probably a bonehead question.
I got my sm420 that will be going into my J10.
The problem is that it got dropped in the dirt (p.s. don't get a 100# woman to help carry a 150# transmission) and some dirt got in the case through the opening for the shifter.
I was thinking about rebuilding it anyway (seals, bearings and synchros), and I guess I have to now.
what do I use to flush the dirt etc. out of the case?
Thanks in advance for any advice
