What would I need for adaptors, and any modifications to convert a stock Model A transmission to a 39` Ford syncromesh transmission? Thank you.

You need one of these from Dennis Cling

It seems the mods don't like links to businesses, so you'll have to do your own google search I'm afraid.

I got mine from Sammy at Arizona Model A.

Cheers

I think it would be much cheaper to learn to double clutch& it would also retain one of the A,s driving experiences.JMO
 
Isn't part of the reason of going to the '39 transmitter the higher 1st and 2nd ? The fact that they are 'circumcised ' is nice, but, double-clutching is quickly learned.

I too have been debating on whether to go the '39 route or a Mitchell with the higher 1st and 2nd. I like the idea of the higher lower gears.
 
I couldn`t even get signed off on driving a Ford 5th wheel tractor with 10 speed road ranger in the military. I guess it just wasn`t ment to be. I have my worst time down shifting going down hill.

There are a variety of gear ratios for the V8 top loader trans, and over the years there has been much mixing and matching of parts and ratios, so check the gear sets on any trans you buy. "39 transmission" has almost become a generic term for any topload V8 trans, even if it has a 37 case, 38 gearset, 39 shifter, 40 synchros.
Any one thinking of putting in a V8 transmission should browse Van Pelt Sales website which has a lot of good info. Here is the link to the gear ratio chart.

The MItchell trans with the 15% higher gearset is fairly close to the 28 tooth '39 gearset. Easier to swap in, has synchromesh, looks authentic, you know for sure what you are getting, but more expensive.
 
Tried to teach my wife how to dbl clutch, it did not go well. 39 transmission for our car so she can drive it without tearing the transmission up and enjoy the car. Rod
 
I have a '39 transmission AND a Mitchell Overdrive ( about 90,000 miles). It is a dream on the highway and a joy to drive here in the Sierra foothills of California. Smooth shifts and Lower engine RPM's

If I wanted smooth shifting of the gears, I would have kept my Ford Ranger with 5 speeds (1990's).

This is a Model A forum...right?

You are absolutely correct, Marc.....However many of us enjoy different levels of driving pleasure. You might be surprised of how many folks have one or two modifications to enhance there driving pleasure....especially as we age and still want to enjoy our Wonderful cars.
