6th-5th grind due to transmission or noob shifting technique? - Page 2 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Sounds like a transmission problem then.

I can promise you it's a transmission issue. There have been a few people reporting this same problem and the dealerships have been replacing the transmissions. Bring it to the dealership. He more Toyota beers about this issue the more likely they are to address it overall.

Dredging up this zombie thread... has anyone found a definitive answer to this issue?
I'm nothing like a newbie- have been driving manual transmission cars for 40 years, from a '63 Falcon with a 3 on the tree and no synchro into first to the legendary Miata with its perfect 6 speed. I've had my FR-S for 10 years and a tad over 100,000 miles.
I started getting a bit of grinding on 6-5 downshifts at around the 85,000 mile mark. Had the transmission fluid replaced at 90,000 miles, taking the car to a reputable dealership and having them replace the fluid with Toyota's factory-spec gearbox juice.
The throwout bearing bit the dust at 100,000 miles (actually pretty good for the wimpy OEM piece) so while the transmission was out I had the shop change out the fluid with Redline, hoping that would cure the grind. No such luck.
So... any idea what's up with this? Has anyone found a definitive problem and, more importantly, a fix?

Another data point... on the way home today, it suddenly got noticeably more difficult to shift into 5th or 6th. 1-4 exactly the same as always, just 5-6 suddenly stiff. I'm going to try replacing the fluid and see if that helps.
