What year????…….Yes, the factory engineers advise to do something, put part numbers on them, use different colors to indicate that there is a difference, and finally, advise in many places what to put where. YOU will find that following those recommendations will make a difference. Factory specs, for me, on these machines are not to be ignored and do make difference. Using OEM parts, especially where the transmission are concerned most often keep these machines off the Craigslist and Ebay sales columns......Good luck....Dennis
