so it's 3:0
I went to the library and got a book on transmissions and start to become more comfortable with the thought of replacing some outside seals. (Somebody had cut part of the MB section out of that Chilton. Can't believe an MB driver could do that. Photocopies are 25 cents at the library. He ruined the book for all others.)
On the other hand, it's kind of intriguing to think that, do to some circumstance, you get the R&R for free and only have to pay for the part, albeit it's an expensive part.
I don't drive more than 4,000 miles a year, as I have a Mazda Miata and a motorcycle to move also. Based on that, my current tranny should last a long time, if milage is the only criteria. It will sure get regular service. But does age play a part?
