Great thread, in large part due to your contributions. The OP is doing a good job here as well. I'm learning from it so thanks. I totally get the 4 speed fun factor. Planning to try out an OD unit. Might blow it up but so be it.:burnout::burnout:
I'm pretty sure when you take the overdrive transmission apart you have to drop the cluster gear in the case to get the main shaft of gears out. the opposite going back in you have to put the cluster gear in the case with the bearings and put the main shaft back in and then pull the cluster gear back up to it which is I don't think necessary doing just a regular for speed. I've already put the cluster in and reverse and fixing to put all the other main shaft gears in all at once.
