Default Transmission issue with a Mazda 6 i


My brother is driving a 2007 Mazda 6 i with around 85k miles. Lately he has noticed that the automatic transmission seems to "jump" slightly when it shifts from third to fourth gear. This does not happen all the time but he is definitely worried about it. Can someone give me some advice as to what could be causing this? ... PLEASE... don't tell me that the transmission its on its way out! okay, please do tell me if that is your prognosis!

Default Same problem - replacement?

I also have a 2006 Mazda 6i with 71k miles, and the same exact problem. It sounds like enough of us have this problem that Mazda should issue a recall on it. I spoke with a district manager at Mazda who told me the best he could do was offer me a 25% discount on parts. He claimed that this isn't a common problem, but later contracdicted himself by saying this is almost always replaced under warranty so it's not a big deal for the consumer.

I have been unable to find a rebuilt tranny anywhere, but can find junkyard parts galore. Does anyone know if a 2005 Mazda 6i tranny will fit this car? It appears that the problem has existed from 2006 through 2008.

Default Mazda 6 trans issues

Some of the Mazda's 6 trans issues are a reflash issue.Most are because it's a Ford trans and Guess what? That is why. It is a Ford trans

Funny thing; the "Ford Transmission" in question here doesn't seem to have any such problems when it's installed in a Ford. Odd's on bet the transmission started as a Ford design, and was then modified by Mazda.

When is the last time you did a fluid change? Hardly time to start worrying about replacing the tranny itself.

Pick-up a quality fluid (dipstick will tell you for certain what formula, manual will tell you how many quarts), a filter, and even consider something like Lubegard additive. I did so the last two times I've changed the fluid in my '05 6 speed and it behaves MUCH better than it did when I bought the car. (I also have an secondary tranny cooler, but that may or may not benefit you)

I don't know your particular tranny has a serviceable filter, but if it doesn't consider adding an in-line magnetic one.

MSDS headers / Magnaflow cat / Racing Beat mufflers / WeaponX coils
AEM CAI / EGR mod / FilterMag / Street Unit engine mount
EBC Ultimax Rotors & Redstuff Pads / StopTech brake lines / Motul fluid
B&M tran cooler / Inline tran filter / Amsoil ATF
Mazda iPod adapter/ CX7 antenna
Continental ExtremeDWS / Bridgestone Blizzak
