Transmission Noise?

[johnnie1]

Just wondering if anyone out there has had this problem. I have a grinding sound when started cold lets up as it gets warmer but is always there. Took it to my nearest Honda dealer "where" I bought it and he said it was transmission spline noise and common on some Goldwings. Had a reg 2012 Goldwing with 43,000 miles and not near as noisey as this 2010 trike with 16,000 mile. Bike shifts great and runs great just not real happy with the noise. Any ideas. Thanks in Advance.

Hmmmmm....My 06 GW makes kind of a rumbling sound until it warms up but then it is gone....been told the same thing...don't worry about it....I am not much help but I feel your pain!

My 12 also makes a little noise when its cold, kind of sounds like gears meshing.

My guess is a thing we call tolerance stack. That is, gears and shafting have dimensional tolerance call outs that state the allowable variations in dimensions when being manufactured So if, back lash on gears is called out to be 0.003" +/- 0.001" you could end up with either 0.002" or 0.004" back lash per gear and still be within the manufactures tolerance. This is true with shaft and spline clearances as well. In a transmission that has several components in series, tolerance stack up can allow one transmission to be tighter than the next one and both be well within the design tolerance. When the transmission comes up to temperature components expand and have a tendency quiet down. I wish our bikes had higher quality gears but then we may not like the additional cost. All in all they do pretty well. We hear the term tolerance confused with clearance a lot, again tolerance refers to dimensional allowables and tight tolerances differs from tight clearances.

I hope this helps.

Thanks for the information, this pretty much is what the service manager told me you just explained it better. Ride Safe.
