So I am a little lost and I just want to understand somethings. So rather than disassembling the transmission and evaluating if anything is actually breaking, your actually replacing the entire transmission as an assembly? So, the transmissions are actually quite simple to work on. A simple service manual explains the disassembly, inspection and assembly procedures pretty good. The only thing I could possible think of is there is an oil deflector plate that is held in place by 2 screws. The drive chain rides right over top of them very close. Could it be possible these screws never had thread locker applied to them and are slowly backing out? But it wouldn't make since that its only under a higher load than just a slower acceleration rates. Maybe something is shifting? That's where a good disassembly and inspection would be good to see if and where the problem is. As far as clutches go, I'm not a good one with a grinding noise. Now squealing, just experienced that on my 850 and i needed to rebuild the secondary.
Also, do you know the torque specs on your clutches? The only reason why I am asking is I didn't know the spec on the secondary and I actually over torqued it and caused the helix to contact the plastic inner cover as things heated up.
