Most of the sensors and suchlike are standard GM goodies of the vintage - used by kitbuilders, custom builders, and the aftermarket. Should be no trouble to keep them available (I usually order stuff like this from Marren Fuel Injection - www.injector.com.)

Core electronics are going to be at issue, but they're mostly cross-compatible within engine (242 to 242, 150 to 150,) so that's not any trouble. I've got a boxful of RENIX 242ci ECUs floating around here, and a handful of RENIX/AW4 TCUs as well.

Per Hollander, the ECUs between A/T and M/T are compatible. I haven't verified this, but I consider Hollander an authoritative source.

The TCU circuit is separate from the ECU, tho, so it makes sense.

You do need a different TPS with an auto vs a stick.

I believe the manual TPS for the Renix was just an Auto one minus one of the variable resistors (the ECU wanted a 0-5 volt signal, the TCU wanted a 5-0 volt signal, or vice versa) so except for possible connector differences an auto TPS should perform the functions of a manual one just fine.

An auto version is way easier to adjust because of the fact that the connector is not molded into the sensor.
