Overdrive for C4

[2+2GT]

What is model number that I should look for ? Is an AOD direct fit?
(Yes, I know I have to shorten axle)

Here is one I found on ebay:
FORD AOD-AODE-4R70W

No, you don't have to shorten the axle. I suspect you mean the driveshaft, or what the British call the propeller shaft.

i haven't been in a car unless it was a 7-6 speed automatic that went under 2000 rpms at 75-80. even then it was close.. i think your goals might be a bit high.

A guy here says he has an AOD for sale. Th number on it is:

RF-E90P-7086
(or E9DP-7086)

Will it fit my car?

If yes, what mods must be done?
