Mark,
Thanks for the advice RE the governor passages. We'll take your advice on that, for sure!

Bob, we've looked pretty extensively for a B & M Modulink kit to replace the vacuum modulator and cannot find one. There IS a kit available for a 700R-4, but it won't work on a TH350.

This car is a hand-built, all-aluminum replica, loosely-based on a "Model A" roadster, and won't be a daily driver, so lots of cruising won't be a part of its operational life. It will not get driven a whole lot. We were told that the manual valve body shift kits wouldn't "jar your bones" when manually-shifted at part-throttle settings, especially, with a fairly loose converter, and if shifts were made in the 2,000 rpm range.

This car will be raced very rarely, if ever.

The owner is aware that every shift will be, of necessity, made by the driver, just like would be necessary with a Borg-Warner T-10, which is the alternative.

This way, he just avoids the use of a clutch.

Am I missing something here? Is there some reason this won't work? And will the transmission function okay without the kickdown cable? I realize he'd have to manually pull it into 2nd-gear for a downshift, but that alone, is no problem. I was wondering if the kickdown lever boosted main-line pressure to the servos/clutches when it was activated by a "floored" throttle.

Thanks for any information; It's MUCH appreciated!!!

Bill
