What is this discussion about?
Mazda 626, Sedan
May 02, 2003 (4:37 pm)
I am looking at a 2002 626 4 cylinder auto with around 7500 miles, the dealer is currently a little under the edmunds TMV price around $13,300. I am concerned about the transmission after reading these posts and looked at the maintaince schedule. According to Mazda they first recommended transmission fluid change at 105,000 miles, then every 30,000 after that.
Did they change to synthetic fluid or did they improve the unit? I am concerned about long term use and thinking of adding an auxillary cooler if I purchase it. Does anyone have any thoughts about the newer 626's transmission's?
Thanks in advance for any advice.

These fluid change intervals for the auto transmission are rather strange. Why not EVERY 105K miles? Would this suggest that these transmissions might last 210K and more? If I owned one of these auto transmission cars I would probably change the fluid and filter every 30K miles regardless. How can you go wrong with that? Adding an auxiliary cooler could not hurt because excessive heat generation is number one reason for an auto transmission failure.

Speaking of swinging vents, and other gismos, please name one other car company that would delete standard fog lights, traction control system and anti-lock brakes from their identical next year model. Mazda did this with the 99 model 626 ES V6. The 98 ES V6 had all those as standard equipment. Do you think they may have saved a penny or two by doing that? I think that most manufacturers add such features to promote safety at no cost, rather than delete them once they are made standard equipment. Safety first, right?
Well, at least they did not delete the famous swinging vents. And they added an emergency trunk release button inside the trunk for those who like to travel inside the trunk.

At least they're suggesting a fluid change; as recently as 2000, the manual was silent on this topic.
The CD4E has been improving over the years, though it's still not what I'd call bulletproof; p100's suggestion of 30k intervals seems quite reasonable, and I'm doing 15-20k intervals on my 2000 model, partly because they dovetail nicely with my actual driving habits.
And tacking on an auxiliary cooler is a Good Thing, since overheating is indeed the worst enemy of an automatic.
If you're thinking of switching to a synthetic - I don't believe Mazda has done so - make sure you flush out all the old ATF first.

They took a lot of stuff out for the fifth-generation cars: they deleted the crotch vent, the dead pedal, the heater ducting for the rear, the vanity light on the sun visors. They even shaved some expense on the swinging vents; previously, they would stop swinging if the center vents were closed, but the later versions run when the button is pushed, whether the vents are open or not. Even Consumer Reports railed at Mazda for this sort of thing, which is why some of the goodies (though by no means all) were restored for 2000.
Emergency trunk releases, incidentally, don't have much to do with traveling Sopranos-style; it's one of those Protect The Children schemes. (Like the kids are going to play in the trunk, given the amount of stuff I schlep around in there.)

I read a number of posts on Dodge Ram pickup truck automatic transmission failures. According to some of these posts Dodge maintenance schedule for these trucks now requires changing transmission fluid and filter every 12,000 miles!!!! Bad transmission history or not, this surely appears excessive. Maybe they are insuring themselves against those who pull 10K lb fifth wheels cross country day after day with these trucks. I wonder if this is a severe duty maintenance schedule or a universal maintenance schedule. There certainly is a big difference between 12K and 105K miles, which is Mazda's first fluid change recommendation.

Your link is very informative. So they too are recommending the Dodge schedule of 12000 miles between transmission oil changes. Well, I guess if you get manual transmission you do not have to do any of this. I never changed oil in my 92 Protege LX 5 speed, never had any problems when I sold it with 125K miles.

I did it twice in my old Toyota Celica (1975 GT); the gearbox was still in good shape when I sold the car at 195,000 miles. (I did once lose a third-gear synchro, which I had replaced, which mandated one of those oil changes.)
#1400 of 2044 synthetic manual transmission oil

I am getting ready to change my manual transmission oil and replace it with Redline MTU 75W90 synthetic oil. I am somewhat concerned about possibility of gearbox axle seals developing a leak as a result of this. The car has 65K miles now. The gearbox oil is still the original oil from the factory, which I assume is not synthetic. Should I be concerned about this? I read somewhere that replacing mineral oil with synthetic oil can cause older seals to leak. Is there some substance to this? Did somebody try this (Redline)oil in a manual gearbox?
