Bringing in my '15 for 4th gear grind w/ aftermarket warranty
 

So I recently got a 2015 BRZ and I noticed that shifting up into 4th at mid to high RPMs gave me a bit of a grind and sometimes I was just plain locked out of shifting into 4th. I know many people have gotten their trannies replaced under the Subaru warranty, but I was wondering if anyone had any experience dealing with this issue when filing a claim with aftermarket warranty companies?



Car's got 34k miles.

Check the brochure the warranty came with. I would assume it would be covered, it's clearly not the clutch as it's just one gear and I don't think you're even at the mileage for the first oil change.

You will likely pay some sort of deductible, was $100 when I used mine (different reason).

I wasn't aware the BRZ transmissions were prone to failure...well that's a bummer. Good luck with the replacement!

Are you confident of your shifting technique? Have you had another experienced driver drive your car?

When you say, "shifting up to 4th," do mean from 3rd gear after accelerating, or from 5th gear so that you have more power for acceleration?

We have about 90k miles on our '13 FRS and the MT has been great.. no issues at all. It doesn't like to be manhandled, though... it slides into appropriate gears effortlessly, but doesn't like to be forced or slammed into gears that don't make sense for what the engine and wheels are currently doing.

If you're an experienced MT driver, then ignore this... Just checking.

Usually from power levels way over stock or asshole drivers

Makes sense ;)

I've only ever owned MT cars in the last 16 years. It happens when I shift from 3rd to 4th at anything over 5k RPMs. At first I thought it was because of user error from being late on the clutch from not being used to this car or being too aggressive but it happens even when I "granny shift" at over 5k RPMs. I did a bit of Googling and it seems there was a slight syncro issue on FRS/BRZ models up to 2015 and a few people have reported getting their transmissions replaced under warranty.

There are multiple people who have reported getting their transmissions replaced for a syncro issue with similar cases to mine in 2013-2015 FRS/BRZ models. It doesn't look to be common since I've only found a handful of reports, but then again I can't be sure everyone who had the problem posted about it online.

Or from the 4th gear syncro issue that several people have reported.

My car is at 32000KM and I'm on my 3rd trans and diff oil fills. That may be overkill, but gears break in and dump a lot of particulates into the oil, if you don't dump the break in oil early, you're asking for trouble, no matter what the maintenance schedule says.

I mean you could be right, but toyota's engineers put a mileage in the book, therefore they can't claim that going over mileage on an oil change caused it.

It's not a syncro issue with 4th, the issue is with the retaining clip. It is listed on the rebuild detail from Jack's Transmissions.

Ah, that makes more sense. I hope my warranty claim works out and I don't have to end up opting for this kit, but thanks for the info.
