I broke a couple of teeth off of the idler gear in my proline trans. Today. After 4 packs thru it. I'm glad that proline made it to were the stock idler will fit in it, because thats the only saving grace for this transmission to make it on the market.The slipper was set from factory and even if u tighen it down all the way down(like all racers have it on their 2wd trucks) it shouldnt strip out the idler.Its hard to find a good plastic idler that will hold up in this application.Replaced it with the traxxas idler. The slipper really makes ugly a noise when it slips.
Other than I couldn't get my pinions to stay on ( never had that problem before)
The transmission has potential with its sealed diff.
