I am doing an AX-15 to AW-4 swap. All I know about the donor tranny is that it has about 150K miles and came out of a wreck. I plan to pull the pan, replace the front and rear seals, and maybe flush the torque convertor. Are there any other items I should check our or replace as a mater of course? I've never worked on an AW-4 before but have auto tranny experience.
