Just discovered that I might need to take my quad into the dealer and have the cases split and transmission rebuilt because its slipping out of 5th gear. After speaking to 3 honda service techs at 3 different honda bike dealers, they all point towards some nipple inside the engine that holds the transmission together. At $115 an hour for labor X 8 hrs approx to teardown and rebuild plus parts thats allot of money.

I found this:
2014 Honda TRX420 FM1E Fourtrax Rancher 4×4 Manual Shift Engine Motor Complete | eBay

And am wondering if its a direct swap. Its the exact same "style" that I have now. I dont care if I have to splice some wiring and change a few connectors. I just want to know if it will work? Direct bolt in swap? Thank you.
