Update: Mileage 2850
Changed out factory fill engine oil (Mobil 1), differential, and gearbox today at the dealership.
I replaced the factory fill gearbox oil (clean and clear) with MOTUL Gear 300 and the Differential (metal filings present) with Gear 300 LS.
Observations and experience: Gearbox is much smoother with MOTUL than OEM factory fluid - especially downshifting into 2nd and 1st. There is a noticeable decrease in previous clunking linkage sounds. Linkage noises are still there (design flaw) but not as loud, and shifting feels more precise.
Noticeable decrease in Limited Slip slapping/clunking noises, especially from 1st to 2nd.
I attribute these improvements directly to the MOTUL fluids.
I have a long trip coming up next week, so I'll get to feel and hear more over an extended time frame and over the interstates.
Update to follow.
