A brand name for your synthetic lube?

Forget quick gear changes. The main concern is protecting the gearbox an d saving it from damage.
When I had my Cord on the road I held the clutch pedal flat on the floor for two seconds each time I changed gears.
Having flow restrictors reduced the shock loading as the main cylinder is really too big for the job.
I found that I had to have the flow restrictors almost fully closed . It is a good modification to do.
I also fitted micro switches to first and reverse gears that let you know when the gears have been selected properly by small lights under the dash. That basically eliminated accidental gear crunching. It all worked very well.

Not really. It will slow down the speed of a gear change. Some changes can be quick and harsh.

Terry my plan has been to install these vacuum modifiers in my car when I start driving it. Being adjustable is a great idea because we can adjust it to fit our trans.

Dumb question: Wouldn't flow restrictors cause a weakened shift?

I too reused the original leather seals and worked leather conditioner into them. The leather conditioner I used is called Dubbin and is very greasy. I believe that the shift cylinder is too big consequently the gear are subjected to too much force.
Flow restrictors are required to be fitted to both ends of the cylinder . George Arakelian pioneered this modification.

I used a syhthetic lube. My original leather cup seals were in great shape. I did purchase a set of neoprene seals. I just felt my leather was fine. I did post many pictures of this work restoring this vacuum.

Hi! what are you all using to lubricate the piston in the shift can. The piston is hanging up and I'm going to have to clean it out and re-lube. The piston has a neoprene gasket.
