Is the transmission the same in an F1 and F3. I have an F1 column shift and want to convert to a floor shift. I have found an F3 transmission. will this work

 

They are different. The F-1 transmission is a lighter duty, synchronized, the F-3 will be a non-synchronized "crash box" transmission. The usual maneuver is to change from the crash box to a synchronized transmission. If you like double clutching through all the gears, and double clutching to down shift, I doubt you're going to like the swap especially having to the modification to make it fit.

You'd do best if you want a stock floor shift to use a pre-mid '50 floor 3 speed out of another F-1. F-1 came with light duty and heavy duty 3 speeds.

You might want to check into switching to a T-5 transmission. Do a search of this board on "t-5", you'll find a lot of information.

 

Thanks for the info. I have been looking for a floor shift F1 transmission for months without any luck to this point. I have a column shift but my son wants a floor shift and while the body is off the frame and the engine is rebuilt I would like to get this done. Does anyone know of a F1 floor shift transmission out there. I have found on person that has the case but does not have the top shift part. If someone has the top shift part please let me know. Thanks

 

Ma Van Pelt will should be able to help you with information on your parts search and maybe a whole transmission. Ford Transmission Parts Prices

 

Body off is the best time to do a T5 swap.

 

Hey thanks for the reply. I went to the vanpelt site and they have a ton of parts. All I would need it the top case. I have the bottom case so if anyone knows of the top case with the shifter please let me know.

 

I have a transmission from a 49 if you are still looking.

 

hi again. Im pretty sure my friend has the top shift housing as well as the case. if thats the one you are refering too? call him again to confirm.
I was at his shop on Friday and I thought I saw an extra one unless maybe it was a customers??

 

Hi All.
In answer to Brian1950. Yes I am definitely interested and still looking. I need a transmission for an F1 with a floor shift. 1949 would be fine. Let me know

In answer to Jmadsen. I spoke with your friend at the beginning of the week and he has the case but does not have the top part with the shifter. He said he would try to located one. I am to call him back in a few weeks.
