that would be cool if it would be that easy like i said i*m not really good with wire
more fixing mechanical or modify it
as soon i can get to it i post some pictures with what i got on switches and sensors
got a question for you what is more trouble swapping to 5 speed or replace the aod
i have 2 in the garage to choose from
if workload would be the same i would think about it
IMO, the M5R2 makes the car much more fun than having an automatic.
Other people want automatics b/c it's easier to launch them in the 1/4 mi.
In your shoes, I believe the biggest concern would be
a) the condition of the "spare" transmissions and/or
b) the availability of the REST of the M5R2 swap parts.
I know lots of M5R2 have worn 2nd gear synchros (both of mine had this issue and they came from <100K mi cars).
Although you claim to be mechanically inclined, You also seem to be in a hurry to get this car moving again. Therefore, in your shoes, I'd probably swap in the AOD for now if you have a reasonable belief that it works and then start assembling all the parts you need for the M5R2 swap + confirming the condition of the synchros (plus rebuild the M5R2 if necessary) for later.
You will need:
M5R2, clutch pedal assembly, brake pedal assembly (or narrow the width of your auto brake pedal), clutch line (or make one), clutch master cyl, and compatible flywheel/starter/clutch [matched to your 5.0 engine's 50oz imbalance) combination, flywheel to crank bolts (will likely be different), and pressure plate to flywheel bolts (may also be different).
Things you can sell once you have the 5.0/M5R2 combo setup working:
SC Flywheel (if not reused), 5.0 TV cable (throttle kickdown cable from throttle body to transmission), SC flywheel to crank bolts (if not re-used), stock clutch line (if you decide to have a custom one made), AOD transmission (someone will want it if it works).
