1. Car - Model and year - early 70's 230 and 220 4 cylinder sedans
I remember changing out 3 transmissions in 1 weekend, in my garage, by myself, car on jack-stands. I had 1 bad one that wouldn't upshift, and tried 2 others. The second donor worked. Lots of fun, believe me. Worst part was unbolting/bolting up the torque converter to the flexplate, and of course, man-handling these bulky things into position.
Second time round, a 76' 450SE, no reverse. I had a donor auto trans, but this time I 'rented' my friend's commercial lift/bay. He helped me out some, when not busy, so we tried changing the valve body, but no go, so removed the old and put in the 'new', with original valve body. Problem was solved in about 7 hours, and $350.00 (CDN) for his time and use of his hoist/bay.
2. Transmission type - all were automatics
3. Dealer or aftermarket replacememnt - all 'donors' from wrecks
4. Cost - I think the donors for the old gals were less than $100.00, and the '77 450SEL was $300.00 (CDN), but I also used the camshafts, and the wiring harness went into my streetrod.
5. End Result - the 2 cars both shifted fine and continued to do so until sold.
