The first Avanti powershift transmission, serial no. 10001 is a red tag unit for rear axles of 4.09 and up. Do records exist that would indicate which Avanti, (probably a prototype) in which this trans was used? Before I put it back on the shelf again, thought I would ask.

I don't know the answer to the question but my powershift has a low serial number like yours and a 4.09 rear end. Mine also has the red tag. Any reason for the difference in tag colours ie is there some difference in the powershift used on 4.09 ratio compared to the others?

I believe in George Krem's "R series" book, available through the Museum store, you can find info regarding points like that. I scanned over one recently and there are descriptions of how many cars had what, etc. It may be in there64 GT Hawk (K7)
1970 Avanti (R3)

63r2, what is the serial no. of your AS4-10 and your car. I'm of the opinion that all the AS2's &4's were serialed sequentially. This is the list I have:
AS4-10 10001 car unknown
AS2-10 10445 R2 R1236
AS4-10 12372 R1 R3832*
AS2-10 14561 R3 R5642
*need to pull the extension housing to confirm that this was the original trans for 3832.

Interesting, Peter. If they were numbered sequentially, then your transmission would suggest that few 4.09's were installed in floor shift cars, at least up to your car's production date. I wonder what the overall split was between floor shift car production - 4.09 and up vs 3.73 and down.

It also should be remembered that in 1964, hardly anyone would buy a performance car with 4.09 gears, and then order an Automatic, there should have been plenty of 4.09, 4.27 and 4.54 Model 44's with FOUR Speeds.StudeRich
