1966 F100 240 I6 T5 transmission?

Hello I am going to be building my new inline six (240ci) in my 66 F100 probably gonna be running a cam, headers, 2 barrel carb and an intake. Getting these parts from Clifford or Summit. I was told I cannot run my ford AOD” automatic overdrive metric” transmission with an aftermarket carb because of kickdown linkages. However this is ok I now have to figure out what tranny I want to run I definitely want a manual transmission and was looking at T5 transmissions any thoughts or ideas any details on how difficult this might be? I already have a manual transmission pedal assembly. My truck was originally equipped with a 3 speed on The collum. What tranny swap would be the easiest and best for a daily driver? And would work with the 240 inline 6?

​​​​​​The T5 is a hydraulic clutch and that can complicate the clutch linkage assembly/swap since our trucks never had one.

I don't see why you can't run an AOD with an aftermarket carb, the fox body guys do it all the time. You just use a Lokar cable:

An SROD transmission could be an option too if you're after overdrive. I had one in an 80 F100 with the 300 six and grew to like it. I believe there is an overdrive 4 speed toploader variant too.

I may be wrong, but I thought the bellhousing for the 240/300 was the same as for the 302/351 V8, and would therefore work with the T-5 transmission. I can say for sure that a T-5 installation will work with the old style mechanical bellcrank clutch linkage similar to what came in your '66 F100 because both my '64 Falcon and '66 Mustang, both with T-5s, have exactly that. No doubt a hydraulic slave cylinder clutch linkage would be easier and smoother, but I don't find it too hard. Good luck!

T5 = conventional trans, bolts to a bell housing, use whatever clutch you want.

M5OD, the 5 speed OD Ford used in later F150s = integral bell, juice clutch the only flavor.

For the OP: You may find OD a bit tall with the T5, as well as reverse. Your rear axle ratio will be the key to happiness with that trans. 4.10s are a good ratio. Easy pulling in the first 4, OD handles the high speeds. Serving suggestion, good luck with it!

Murphy, I might suggest looking at a mid 90s F150 I-6 - AOD setup for your truck.

But if I were starting new, I would look hard at a current EcoBoost auto setup for the best of the best.
