Couldn't get into 6th
 

so I was on the highway and had to pass a bunch of cars/semis/trailers quickly so I (did not) pass going 160kmph. but when I tried to get into 6th I couldn't so I had to get back into 5th. but at lower speeds it's easier to get into 6th.

why is this? or am I just crazy?

Couldn't get into 6th
 

Just one of those days when transmission not happy with you. Next time it will be ok.. ;)

Jokes aside sometimes I have problem getting into 5th from 6 when I'm going pretty fast... I take it as just one of those weird things with this transmission...

Hmmm... sounds like a typical missed shift. If pumped up on adrenaline, did you perhaps release the clutch pedal before getting it into gear? It happens.

Also, sixth can be kind of awkward. Even a little dangerous if you're not paying attention. If you don't have that lever hard over to the right it could bump up between 4th and 6th gates or even worse, drop into 4th which, IIRC, would be money-shift territory at that speed.

nope. I kept the clutch in. ever since I pm'd you awhile back I've been very careful. when I couldn't get into 6th I kept my foot on the clutch and brought it back to 5th

Oh, yeah! I had forgotten about that. :cheers:

edit: How many miles on the car now? It took my trans 10-12K miles to really break in the syncros. 6th is still a bit chunkier than the rest.

Couple of times, I've experienced a balk from the gearbox when shifting quickly from fifth to sixth at relatively high revs.

were you all the way to the right with the shifter? maybe the vibrations and torque from the engine while driving it hard caused a slight momentary shift in the transmission due to the soft OEM bushings when you were trying to get into 6th, causing you to miss the gate. I have never had this problem before, but there have been a couple of times where I missed a 5th to 4th downshift because I couldn't get it into the gate, but that was most likely user error

under acceleration, I am just shifting from 4th to 5th at that speed.

it's not my daily so I only have about 5000km lol. it seemed fine shifting at lower speeds. you gotta take your car up here to Canmore. very nice here


nope. I don't remember what rpm I was at but probably around 5500-6000. and thanks for the explanation. it does make sense

Oh hell, it's still brand new! The syncros won't start grabbing effectively until about twice that distance. Next time it won't go into any gear, no worries. Just release enough to go back into neutral and apply steady pressure a second time.

I apologize if I'm repeating myself but it's not like a switch. The higher the RPM, the bigger the difference in RPM between gears, and therefore the more work the syncro has to do to match speed between input and output before allowing the gear to engage.

Been threatening to visit Banff for a long time now. The missus is all in. Just have to carve out a few days to tool around.

When you get to Banff make sure to leave some time to go up the Icefields Parkway to Jasper. FKNA beautiful road!!

@Atticus808 eventually you might want to change out the gearbox oil for some motul gear 300 or other recommended brand

I don't have a twin yet, but if it's effectively a "syncro" problem, then a quick tip is to go back to neutral, release the cluth and press it again and then shift in the desired gear, effectively doing a "double clutch" shift.

Added to the plans!
When I first got mine, which already had 1800 miles, I was a double clutching fool because I couldn't bring myself to yank as hard as it took to downshift normally. After about 5K miles I started noticing improvement which continued steadily through about 20K.
