Dumb question: anybody tried a A500 trans in that body-style? My understanding is that the A500 is a A904 with overdrive (and the A518 is the 727 with overdrive).
The A500 (42RH) is basically a 904 with an overdrive 4th, so it's a 4 speed 904.
Some had a lockup converter which connects the engine directly to the trans mechanically. (feels like being in 4th or 5th in a 4 speed or 5 speed car.) so technically 5 different speeds.
When in lockup the trans cools better because there is no converter slip friction heating up the fluid.
Also the engine to trans directly being connected means less loss of efficiency in the drivetrain, so it also helps with fuel economy on the longer drives.
Didn't see anywhere (maybe I missed it) how the car is normally driven, but just off the top I think a lockup 904 would be an easy and totally worthwhile swap behind a 340 but what do I know? :D:rolleyes:
I realize a lot of this information was already discussed, I just thought it would be nice to have it all in one place and not all be in transmission guy language.
