Interesting question as I am also "refreshing" a A833 gearbox.
I purchased the Kindle version of the Jamie Passon book "Chrysler A833 transmissions : how to rebuilt & modify", and Mr Passon highly recommends to use silicone RTV on the bearing retainer gasket and bolts.
Just my 2 cents, I know nothing about gearbox and I learn something every day :rolleyes:
@Dan Brewer : I will order some parts from you, but I wait January and the return to normality after the end-of-year festivities. I hope you have reasonable international shipping fees :)
