I have a chance to pick up a T-350 that was built by a trans shop with high performance kit. B&M. I know this guy and he is very good with transmissions. He makes a pile as he always has a new diesel dually.

Anyway the T-350 has the short Tail shaft and 2200 rated stall converter. The converter is new. I can steal this unit for a Dinner at a big steak house.

The trans has been sitting covered in a plastic bag for about 4 years. It spins over freely and the shifter arm is smooth. It's basically clean and ready to use.

What would be a good starting proceedure to use this trans?? Fill with fluid and start it up???
