Also try Bert's, (800) 321-1931. I don' know the current status but I think they used to have them.

Re: Adapter Kit.. ‘39 trans to A/B engine.
I have had the V8 trans in a previous Model A and am getting ready to put another in a different car.
I bought a kit from clings about 3 months ago. To my knowledge, they’re still doing their thing.
I just don’t like the original non synchro trans.
I also prefer the gear ratio in the 39.
No difference on final drive obviously.

Re: Adapter Kit.. ‘39 trans to A/B engine.
The main reason for installing a later later trans is that it has synchros, which the Model A trans does not have.

Re: Adapter Kit.. ‘39 trans to A/B engine.
I put a 1935 trans in. It does not have great synchros but the second gear ratio is much better than the Model A trans. The 1935-1938 transmissions have the better gear ratios and Ford improved the synchros every couple of years but the 1939 (and later gears put into the earlier cases) has the best synchro's of the series.
Mitchell's also offers a sychro trans with improved gear ratios. I think they run about $2500 plus shipping? So a 1939 at about $800 to $900 plus the adapter kit at about $700 adds up to $1600 but when you add two separate shipping costs it would be about 3/4's the cost of the Mitchell but the Mitchell has new gears with a warranty from a good supplier in the hobby.
Part of my choice of the 1935 trans was that it gave me the ratios and I would live with the weaker synchro's because the earlier transmissions are about half the cost of the 1939's.

The only problem I observed with the earlier syncs is that you couldn't shift quite as fast. You should be able to get a hundred thousand plus miles on a properly rebuilt transmission so I have never noticed the difference in life between my '32 with the original transmission and a '39 transmission.

Re: Adapter Kit.. ‘39 trans to A/B engine.
1930's gearboxes are rare here but I have a 1935 one in the workshop. If the synchros were updated every couple of years, were there changes made to the case? In other words, can later gears etc be put into the 1935 case?
That Clings adapter doesn't look like it would work for me but I'd have to see the other side of it.
The more I think about it, maybe a Mitchell at about $5,000 is the better way to go because it would cost big $ to graft the '35 box onto the A flywheel housing and be able to mount the clutch and brake pedals.

Here’s the RHD adapter.

Re: Adapter Kit.. ‘39 trans to A/B engine.
Sorry for the confusion. When I said "weaker", I meant they were not as good at synchronizing. I don't know that they won't last just as long as the 1939 synchros. The 1939 (and 40-4?) gears and sychro's can be fit into the older cases. Some cases with some gearsets require some grinding for clearance. I don't know the exact combinations but you cannot just change the synchros, you must change the entire gearset and shafts.
Cling's has the right hand version of the adapter.

Re: Adapter Kit.. ‘39 trans to A/B engine.
Thanks alexiskai and GeneBob. Very encouraging. I'll do some more research on switching parts from a '39 gearbox. I'll need an input shaft at least because the one in the gearbox now is quite rusty. The gears change smoothly though and there is no water in there

Re: Adapter Kit.. ‘39 trans to A/B engine.
So according to the link that Alexskai posted, the later V-8 gears will fit in the "B" box. This sounds like the way the go with a Model A instead of adapting a V-8 box using the Cling adaptor kit. And a whole lot cheaper.
Or did I miss something?

You still need the parts of the kit that mount the pedals and support the wishbone. I am not sure they will work with the "B" transmission.

Re: Adapter Kit.. ‘39 trans to A/B engine.
Not sure it would be cheaper – as Charlie says, you still have to adapt the B transmission to the A motor. It doesn't bolt right on. And it seems like there would be a greater supply (and thus lower cost) for V8 transmission housings and parts.

Re: Adapter Kit.. ‘39 trans to A/B engine.
I think most parts are interchangable 32-39. I have a mix and match with a 37 case, 38 gear set, 39 synchro. I have the 39 gearset which came in the 37 case when I bought it but I liked the 38 ratios better. Van Pelt mentioned above has about everything you need to know about these trans. Buy his book.
