You know why automatics are sealed these days? They don't expect them to need service. Here in the U. S., I actually had to call around to find someone that would do a clutch. When I was a Firestone mechanic lo those twenty some years ago, we'd drop a tranny and throw clutch plates in all the time (book time paid more time than it took me to do it). Neither of the local Firestones would touch it when I called.

Point is, automatics are pretty sturdy these days, and there are fewer shops in the U. S. that will work on manuals anymore.
