been there done that, i now have a paintstick marked on the direction they go---lol
even funnier is I bought my Maxx's used and the one I popped the tranny-rebuilt it, put a forward only in when I rebuilt it and all four were spinning backwards---lol here the guy I got it from had put them both in backwards and I raced it for a year in reverse---lmao when I figured it out---but man o man was i confused when I fired it up--first I though it might be running backwards?? shut it off and started it up bunch more times and the same--then I thought I had screwed up being my first time rebuildind a tranny-- took me a damn week to figure it out--lol
