They said it took over a month to find a less bad one for $1000 that they were able to use for parts to combine with the original to make a working unit. They said there are several parts in those that are often worn that are really hard to find these days. Their theory is the wear comes from continuing to run a unit that is just old and tired. A soft kit and a tune up every 15-20 years would prevent those issues.
It's great to have reverse again. Overall am very happy with the work done. I would like to ask for feed back from others about how noticeable the the 2-3 shift is on your vehicles. The 1-2 and 3-4 shift are almost imperceptible, but the 2-3 shift feels almost like one is pushing a clutch in on a manual transmission. It doesn't seem to upshift fast enough on the 2-3. I decided to drive it for a couple weeks before bringing it back to the shop for any adjustments they can do. I've read about others who have had results from the TV rod being adjusted. It isn't a harsh shift just kind of annoying. I don't remember how it's supposed to feel from when i was a kid learning how to drive the same car in the 60's.
