I know its a silly question but what would be the best RTV to use when installing a new shifter or isnt it really that important? (ie tri-ax, pro 5.0 etc)
And don't put very much on it. Very thin bead at most. Or just dab it and spread it with your finger. I don't even use it on the shifter any longer and it doesn't leak, so you don't need much unless you have some gouges in the mating surfaces.
I take my trans in and out several times/year, so I hate cleaning it up and redoing the sealer. Last couple of times I just put the shifter base back on after putting the tranny back in and it was fine. I think the sealer is more important on the base of the stamped steel stock shifter base than it is on the machined Steeda Tri-ax base, which seals up pretty good by itself.
