Title: How to best store a manual transmission?
Post by: cleandan on April 08, 2025, 08:36:10 AM
Last year I installed a five speed transmission in a 1965 GT350.
I removed the original 4spd manual and carefully tagged everything and crated it up.

I'm considering a full rebuild of that removed transmission so it is ready should it ever get put back in service....or to have "proven" status for the next owner of this car.

This transmission will remain with the car because it is a significant part of the original driveline...so it is being kept if only for that reason.

Part of me wonders if a full rebuild, only to be put it away for, likely a long, long, time would be sort of a waste due to what sitting unused does to these parts.

On the other hand, having it fully rebuilt, with receipts, would show it is in good condition...even if it would need gaskets and seals redone prior to use 20 years from now.

What do you think?
Rebuild, pickle, label, and crate/store for long term?
Leave it as-is, in need of a rebuild, label and crate up?

What do you think is a good long term storage method for a manual transmission?

Thanks and have a great day.

If it was mine, I would have the transmission rebuilt now, put a plug or old slip yoke in the tailhousing, fill it with gear oil, and put a plastic garbage bag around it. I would spin the input and mainshaft now and then, to keep the gears covered in oil, and putting some desiccant in the bag to help absorb any moisture while in storage. If you were to wait 20 years or so, who knows if you will be able to find the parts or a person able to rebuild, a by then, 80 year old transmission.

Thanks Rory....You are thinking the same thing I have been thinking.
