I dont' think it's hard to replace parts. But, I dont' understand all the fluid flow, etc. However, transmission couldn't grab my interest. It's like wiring in the bulk head. I hate it. Lot's of things I enjoy about cars, but those things I do not.
I like doing the transmissions because you get so much bang for your back and you can do all of it yourself...
At least as compared to doing the engine..
