Transmission Questions

[doctorcharles08]

I just bought a 69 F 100 and the previous owner told me it had an Automatic 4 speed. Is this possible? It has a 360 in it when I drove it I only felt it shift twice although I figured it would be a C-6. Thanks

not if its a c6. only if its a aod would it be a four speed. overdrive being the four gear init.

There are no overdrive transmissions that bolt up to an FE. I'm sure the guy just didn't know WTH he was talking about, and that you've got either a C6 or Cruise-o-matic/FMX.

Thanks I didn't think it was a four speed. Are there any advatages of either the C-6 vs the Cruise-O-Matic?

The C6 was developed later. Supposedly a little more stout and and can handle more abuse, not to mention easier to get parts for. I have no experience with the FMX though.

Do you think the C-6 would be cool with a 390? Not doing much to it just an electronic ignition, headers, aluminum heads, and 4 barrel.

The C6 is a pretty darn durable auto. If I had to have a slushbox, it'd be a C6.

390 FEs were mated to C6s from the factory all the time back in the day. You'll be fine.
