I just picked up this case w24b and i want to change the drive shaft seal in the TT2421 allison transmission,It leaks when the loader is shut off but not when working.Its the seal behind the park brake drum.Just concerned on if the old seal can be pulled out without any major tear down of the tranny asides from pulling out the yoke.This is my first post hope Iam in the correct place.Thanks
