Just wondered if there was one gasket sealer you guys preferred over another for your transmission gaskets? Thanks

Gaskets usually don't need any further sealing if the mating surfaces are flat and without any burrs or debris. If needed I would choose a spray on sealer.

3M Gorilla snot weatherstrip cement = no leaks or weeps !!! most all parts houses & hardware stores have it

get a silicone gasket sealer, one that you don't have to use a body grinder to remove the gasket the next time you work on the trans

Spray COPPERCOTE works almost everywhere,,,,,,

Forget the 3m weather strip cement if you ever plan to take it apart again. real pain to clean off.

I just use grease. If I need to take the gearbox apart the gaskets will come off without tearing.

Try Yamabond4, available for about $10 a tube at Yamaha dealers, Harley and Honda have similar products but I have not used them. It is a non-hardening product, that stays flexible. I have used with gaskets on engines, transmissions and rear-ends and without gaskets on crankcases and oil filled chaincases. It seals extremely well, future disassembly and clean-up is easy. I have used it on air and water cooled car and motorcycle engines with great success. Good stuff.

Just use the old standby of non-hardening Permatex.

I just grease the gaskets for the dame reason stated a few posts above. It's gonna be me working on this thing in the future, and a that point the old gasket just comes straight off, grease a new one and back together.
I only use "stuff" on the joint faces if the faces are compromised, and only if it's to big a job to reface the faces.

I have a side-loader trans with one corner broken off the side cover. It had been sealed with RTV and the PO tried to pry it off with a gasket scraper. Didn't turn out well...
