VOTE: Your Transmission 6MT? Butter smooth? -or- Problems?

[hmong337]

Lately, there have been a ton of people saying their gearbox is having issues and I can't stand to see another post about somebody blaming the assembly from factory (especially when their car isn't even turbocharged).

I lean heavily in favor that the people destroying their gearboxes are destroying them from their own noob skill. For sure, there are a certain few that are busting them from power. And lastly, a miniscule percentage (0.08-1%) of owners that genuinely received a miscalculated assembly from factory.

But I'm betting it's the very large majority of us that are rowing this AZ6 just perfectly fine. In fact, it is only getting smother and smoother as time goes.

Please vote. I hope the poll speaks for itself.

Crunches into second when cold from the 300km mark of ownership. Tried different oils, one made it slightly better other worse. Dealer says the crunching is normal and won't do anything about it. Going to try some Motul Gear 300 and mtech springs to fix. If no good will contact Toyota directly to get it fixed.

Not a manual noob, driven nothing but manuals and double de clutch on the downshift in all the cars I've owned. Car is stock as a rock.

Sometimes going into 2nd is a little choppy when its cold outside, but this car is a joy to shift when warmed up and driving hard.

All gears are smooth but every once in a while i get a slight rub going into 3rd. I'm not sure if it's the cold tranny or if it's just sensitive to rev matching. It's not really a grind but you can definitely feel it when shifting. Also, I've been meaning to ask, i test drove the 2015 limited prior to buying the Series blue. Not sure why but shifting feels much better on the series blue. I'm not aware that they changed anything between the trim levels.

Super smooth except when cold where 2nd is reluctant. I like to let the car warm up before driving hard anyway so... No big deal. You've got to listen to what it's telling you, not just have your way wit it...

Same as my old FC3S or Camaro SS with short shifter, notchy when cold, smooth when warm. The price you pay to have short, engaging shifting.

It is absolutely butter now when warmed up after switching to Motul Gear 300. Just to be clear, it was fine before, but perfect after the fluid swap.

2nd gear when cold has always been notchy.

4th gear in high RPM's causes slight crunch.

I should maybe ask...

How many people voting are new manual transmission drivers? Or have been awhile since they've had a manual gearbox?

Motul Gear 300 won't fix it, I'm running that (less than a year old) and still get crunching when shifting too fast when it's cold. By shifting too fast, I mean faster than it wants, not slamming gears.

Doesn't happen every shift, but I'd say about 30% of the 1-2 shifts until things are up to temp have some sort of crunch. It's not a full out grind, but still not great.

I've been meaning to get it checked before my warranty is up, really need to get on that now that I'm over 90k km's!

Experienced manual driver. Crunchy 2nd when cold. Motul fluid change didn't help. I learned to live with it.

It's been about 6 years since the last time I drove a manual transmission vehicle. My last was a '95 mitsubishi eclipse. So I'll freely admit that the shifting problems I encounter are my own. When I do get my shifts right, it's butter smooth. Like everyone else, 2nd is stiff in the cold. Although it does scare me a bit about people and their tranny problems.

I live in California, so my BRZ doesn't see any cold weather.

I have 0 problems with my manual transmission. I've only grinded once and that was driver error.

[nick_318is]

Mostly smooth, a little notchy when cold going to 2nd, I find double clutching when it's cold makes it a non issue.

Don't do that unless where you live is really hot. I tried it, as have a few others. It didn't help at all and at about 5-7 deg C it was down right dangerous as I (we) couldn't get the transmission into second.

My car is in storage presently, but before it went in I switched to a mixture of redline oils, the one rated for our transmission and the next step down. That was on par with the factory fluid for shifting smoothness. The next time, I'm just putting in the next step down fluid.

Lots of guys are running Pentosin <SP?> and reporting good results aswell. I would have gone that route but redline is about half the price for me.
