Return of the “what transmission oil”

[Nishijin]

Hi all,

 

Bought a 2016 300rr and the dealer put 10w40 tranny oil in it. Not Elf.

 

Took for a practice. Felt fine until hot-hot and then refused to find any gear except the one it was in, had to turn off or wait until cool.

Prefer not a light-switch clutch. What was the decision after the past decade since people chatting GRO?

So nothing has changed?

Assume you mean Dex 6, not Dex 11?

 

Might try some D6 before spunking on elf.

I find it hard to believe 10W40 oil could cause that malady.

Me too but I’m trying to do the simple things first, like changing oil, before kicking a fuss with the dealer it came from.

 

Practice area was mild, not overly hot, mid-evening (UK, so 20° maybe more). Easy rolling practice around some trees on a slope. After a short while it was getting tough to change gears. After an hour it refused to change and refused neutral unless off. 
 

After riding down the lane back to the van and the bike being a bit cooler, it would shift a bit easier.

Off and cold, the shifting feels a bit clunky but monts are new to me (vs the ‘83 TLR, ‘16 Sherco, and all the trail and road bikes).

If you can't get ELF HTX740 then GRO TRANS EXTREM 75W is the go for the transmission oil from my experience, never had an issue with either.

Kubota Premium UDT Hydraulic/Transmission Fluid specifically formulated for transmissions with wet brakes as well as power steering and power takeoff units with wet clutches 👍 At a small fraction of the cost of what those other guys use, I can change it out twice as often and still save money.

The 10w40 should be more than up to the job unless it’s very poor quality. These things will happily change up and down without the clutch just by matching the revs. My gearbox is 20 years old and never been touched!!

I have always found 10w40 to stand up better to heat and more abuse than Elf and light gear oils. The lights ALWAYS give a better clutch when cold but they get very grabby and snatchy when working hard. I run Motul 300v factory line for both engine and gear box. **** when cold, but isn’t affected by heat and hard riding.

Another thing with the Mont clutch is that you generally need full pull of the lever to find neutral. Any fingers between the lever and bars makes finding neutral tricky. Using the short lever helps, then it’s just 1 finger right at end next to the ball.
