Thanks for the useful information, Doc. I gather that any of the 722.3xx transmissions can bolt up with the M119 bell housing after some research on 500Ecstasy. Electronics are probably a different story entirely.
The car is crossing 162k miles, but has been well-maintained for the past 30k miles that I've owned it. Transmission shifts hard when cold (could be sticking valve) and demonstrates a nasty flare when the modulator was set past the halfway mark. I suspect worn clutches instead of the usual vacuum problems. The engine is slow to reach max speed when the kickdown switch is engaged, and occasionally "bogs" a thousand RPM after it does.
The differential mounts and flex disc are in great condition, yet the rear end occasionally "slams" into gear. I have read this could indicate pinion lash requiring a differential rebuild. One of those cases where I either pay up front or have my wallet shredded to death by a thousand paper cuts ;-)
What do you think?
