Hi guys, Can anyone advise me on a modern replacement gearbox for my 29 A speedster. Currently I get arount 98mph using a high speed diff and three speed box but I think if if change to a 4 or 5 speed box i can improve. Also it will make cruising easier on the revs.

Thank you in advance.

Thank you.

Although my A will never hit 98 Miles Per hour I find absolutely no fault with Henry's transmission. If you want higher gearing why not install a Mitchell Gear Spliter or a quick change rear end? I get more speed out of mine by simply using 750x16 tires on the rear. :-)

Hello, the problem is when changing down at high revs, hill trials the gearing is wrong. But thank you for your input.

If you drive 98mph in a Model A, I don't think you are long for this world.

Maybe he runs at Bonneville, or TROG?

Some folks used to mate early '60's Peugeot 403 ? trannies to A's; I like the Ford F150 pickup setup.
The photo looks like a Bentley from the period !

Look for a Liberty or Doug Nash 5-speed. Basically it is a clutchless transmission during shifting.
