#1843 of 2547 1994 mazda transmission leak...any suggestions?!
Sep 02, 2005 (4:13 pm)
I have a 1994 Mazda 626, which is now on its 3rd transmission (the original blew up in 1998, the second in 2003) Now, lucky me, it has a leak at the seal between the engine and transmission...that is what the mechanic told me ( i know a slight bit about cars, not enough to fix big troubles...can't remember what seal he called that). I was wondering if anyone had success in using anything to repair these without taking out the seal( ie without the huge repair bill! ) I read about using a product on the outside of the seal called Right Stuff gasket maker that is put on outside of seal. I don't expect a permanent fix, but was hoping to get this car through the winter, or at least for a few months until I can afford to buy a better used car. Anyone have any other ideas? If not, does anyone think I can keep driving and topping up the fluid for a few months? It is not a giant leak, still shows full even with the little spot on the driveway.

I replaced the transaxle seals and they were not very expensive. My tranny threw a spot of oil when hot and downshifting under load. I ran the car like that for 5 months and my auto tranny rebuilder told me it would last for a least that long as long as I didnt go faster than 80 mph and punch it hard. He said change them at my leisure , just keep an eye on it.They are left and right transaxle seals if thats the ones he told you. They frequently go according to the Haynes manual I have Do not overfill tranny as that will cause undue pressure on it.
Is it a four clylinder? I have the bills here the parts were FW 50-27-238 and list price was 6.60 each pre discount at Mazda dealer. It cost me less than $45 to have them installed and if you can find a decent mechanic to do them it might pay to go the correct route.
If you have the 4 banger could you look at my post above yours #1842 and answer the question I have posed there.
Thx Good Luck PGP

The mechanic said it is the seal between engine and transmission...he said to replace it would involve lifting out the transmission, which is why it was expensive. I didn't get an exact price,but he said it could be high hundreds due to labor costs. He just did a quick inspection on hoist as he was closing for long weekend, but so far he has been a fair and reasonable mechanic. I am guessing that it must not be the ones you are talking about...unless replacing them helps the other?
Odd part about it is about 6 weeks ago we drove just out of the city and back, and as we drove back noticed funny smell. Got home and tranny fluid was gushing out- could see the trail of it as I parallel parked, big pool under car. It had been filled a month previous, now almost empty. Filled it enough to get to garage, did tranny flush and wash, refilled with gasket sealer too, they could find no leak...they took it for lots of test drives, nothing. It has been fine until yesterday when I drove to the far end of the city and back, and saw leak (smaller, not a gusher). The problems seem to hapen when it is driven far (not fast- mostly city streets)...problem is I now need to drive it across the city a few times a week starting Wednesday!
Thanks for the reply
PS It is a 4 cyl. I will check mine later today and get back to you about the filter box.

I checked mine, and there is no gap. The box closes tight on all sides. I do know we have had trouble with it closing when we changed air filter...took some force...I think it is just a poorly made piece.

The funny smell should have been accompanied by some smoke. Tranny fluid leaks and usually drips onto the frame or nearbly and the fan or highspeed driving cause it to flow back and land on exhaust system. Then it smells and smokes due to heat.
Well thats quite diiferent than what caused mine. Mine threw fluid after 2 hours high speed drivng and then on mountainous roads passing antoher car ( DOWNSHIFT). But driving far in your car could cause it to run at the high end of its heat range , like mine from high speed driving for 2 hours. It might pay to get a second look unless you really trust mechanic?
Its not so easy to tell when its on a lift. Might pay to wipe it all clean and take a second look. I also installed an external cooler on mine to keep tranny temp down. They only cost $50 and not too much to install and taht might keep temperature in normal range. As it gets hotter pressure increases also and really pushes fluid out. I had mine rebuilt 4 years and 16K miles ago, and rebuild guy told me the seals that went on mine are very common when running very hot . Then they almost close down again by themselves. ALMOST. After mine threw about 1/2 liter it didnt leak at all again for the 5 months till I got around to changing seals. I do not know if an engine seal would be the same. The tranny seals are like donuts. I am looking atthe haynes manual and they list Gasket leaks, Seal leaks, and Case leaks in that order.TRy degreasing the are wiping it dry driving for 15 minutes and then looking to find EXACTLY where the leak is from. Would hate to see you get srewed by an unscrupulous mechanic. Again I would suggest a second opinion, unless some one here suggest otherwise

Thanks for the info. and advise. I will look under the car again. The car is reaching the point of being given up on soon...but I am hoping for a few more months! It has been a all along...although with the constant repairs, it is almost an entirely new car!
Thanks again, good luck with yours.

Check out the Idle Air Control Valve - my speculation is that you have the Air Conditioner on. try it out with the AC off and see if it still surges. then move the gear shift into neutral while you are stopped and see what happens to the idle. There is an idle adjuster screw on the aft corner of the throtle body == turn it left 1/4 turn and see if that helps. I've had all of these problems, and a CEL OBD code for 1507 and 1504 - Idle Air Control issues. You can also remove the idle air control valve assembly from the throttle body and clean it carefully with carb cleaner spray - it resolved about 90% of my issues.
#1850 of 2547 coolant overflow tank conerns
Sep 06, 2005 (6:40 am)
about 9 months and 20,000 miles ago, my car started to overheat. Long story short I took it to the dealer and the overflow tank was split at the seam. It was replaced under warranty of the car (which is now expired). Well, the other day my car starts to overheat again...so I pull off the road and sure enough the bugger is shootin' fluid out the seam. I called the dealer and of course the warranty on the part is a year OR 12,000 miles.
Anyway I am now on the hunt for a used overflow tank. They dealer wants like $80 for a new one. my question/concern is whether this is a known problem (I have scoured the message board here and haven't really found anything on the overflow tank issue. If it is not a known issue, what can cause the overflow tank to split the seam like that in such a short span of time. Any help would be appreciated.
#1851 of 2547 Mazda 626 '94 Won't Start...help!
Sep 09, 2005 (8:54 am)
I have a 94 626, 4 cyl manual. Car just quit starting. One night it worked fine, the next morning wouldn't start. It does everything it is supposed to except fire.
Took it into CrappyTire (ie Canadian Tire), they have spent 3 hrs and don't know what the problem is!!! Go figure.
The "mechanic" says it turns over but doesn't fire. I thought it didn't turn over. As I crank the key it sounds as though it will start but doesn't "catch". A friend checked out the starter and it seemed fine.

The exact thing happened to mine a couple of months ago, drove home in pm, no start in am... car sounded like it wanted to start, just never made it all the way there. It wasn't the no start sound you get from battery, and would make all the usual sounds of starting right up to the point of where the engine kicks in (hard to describe, but sounds familiar to wwhat you said) It turned out to be a faulty spark plug wire. We replaced the wire set and is fine...well except for the leaky transmission I wrote about a week ago!!! In replacing the wires, we first checked the plugs ("we" as in the mechanic did and told me they were ok...he thought it could be either plug or wire)
Too bad it is at Crappy, they are trouble. If you have any way of taking it somewhere else, I would recommend it (I have a friend who used to work there, the stories he tells.....)
