Mitchell Syncho or V8 gear ratios

Well-known member
Is anyone running the Mitchell (15% first and 15% second) synchro transmission or a V8 transmission with the 15% 1st and 15% second gear ratios (28 tooth cluster)?

If so do you have any problem starting out in 1st gear with the "tall" first gear?

What rearend ratio are you running?

Thanks
 
I agree with oldredford. I'm running 39 gears with 3.54 rear end--B engine at 60 70 hp and lightened flywheel. This is in a roadster. If your car is heavier, you might be happier with 3.78 rear gears. Starting out is not a problem. Parades are a problem.

On the Mitchell transmission with a 15% overdrive on first and second gear, what is third gear. Direct?

Yes direct in 3rd with Mitchells and V8s. These are not ODs as such ... just high gears in 1 and 2.

Thanks to all for replies.

My Coupe is similar to yours, 3.54, B engine and etc and as I remember you are at about 6000 feet as I am.

I will give the 16/28 gearset a try. If a problem I can change to the 15/29.

Thanks
 
I’m using a 15% over 1st & 2nd with a strong stock engine w/26% over drive all Mitchell 3.78 rear end in 1928 Tudor used for club touring. I have found no problems getting it moving from a stop even uphill on pavement from a stop but have found that on some dirt roads with a steep rough grade starting out or driving real slow the tires will spin. Now that’s the only time that I found the granny gear might help. I found with the stock transmission gearing I was losing my momentum shifting to high due to the RPM drop shifting to high gear climbing long hills. The 15% 2nd really makes for a better change on the engine power keeping the RPM’s up shifting to high gear.

It works and it works well. If you go for the Mitchell, choose the 15% advantage for first and second. It's a dream box to row through gears.

Thanks for the post. I was wondering how that combination would work. It is probably around $4500 plus.

Benson,
You have a lot of choices..which is good!
I think what body style is 'somewhat' important(not mentioned)in the final equation..no?
Anyway, in my roadster: '39 synchro with zepher gear set ; 3:54 rear gear set. Note: A very knowledgable model a guy said ..won't work/too high,etc.. It runs out very strong/lengthy in first/second;)!! Cruises with low engine rpm in high!
In my '29 sport coupe: rebuilt stock trany with 3:27 rear gear set. Power first/second gears and lower engine speed in high for touring! Like I said many choices. Good luck
