having burned up my transmission here is what info i have on it first the transmission is from a swing axle bug and has a bus shift cone on it second the side plates that came off your snow trac transmission have to go back on the new transmission as the plates are drilled for oil flow out of the axle tubes i had a 4-10 ring and pinion put in so we will soon see how that affects preformance i have to replace both outboard seals when they come in i will post the cr numbers other wise putting the varriator on has been a relitively easy job i also painted over the krusty orange paint in the engine compartment i will also be rebuilding the wiring harness so wires going to the right side of the engine compartment will go around the back of the fire wall and i won't have the wire harness draped accross the top of the engine i also plan to relocate the floor heat duct to the center of the fire wall so i'm not melting my feet keep in mind mine is a early model 1962 they may have changed transmissions in the later years but i now have the sealed shift shaft and not shur what im going to do about the vent either plug it and vent it out of the varriator tubes or run a piece of plastic air line up to a high spot.the other mod i need to mke is to add a sand seal to the crank shaft so the crank can be submerged with oout filling the crank case full of water there is no seal on the front of the bug motor so if the crank goes under water the helix will draw the water in and fill the crank case with water
