that part number won't help me since i have a 95 but out of curiousity how much was a washer from the dealer? i'd have to wait a week to get mine probably...

i found the transaxle and i saw two large bolts... one facing directly down and one facing down at a 45 degree angle... is the one at an angle the fill bolt? and if so how do i get the fluid in when it is practicly facing down? doens't make a lot of sense to me

Part No. Again

I would think that if both our transmissions have the same size fill and drain bolts that the part no. I listed would be right for your car, too. I ordered my washers from www.mazdastuff.com

Since the washers were part of a larger order, I don't remember what they cost but I know they were very inexpensive.

In answer to your other question, the large bolt facing straight down is the drain plug; the same size bolt facing forward and down at an angle is the fill bolt. When I filled my transmission I used a funnel with a long tube placed tightly in the fill hole. I poured the oil in the funnel slowly and had no trouble filling the transmission without any spills or problems. To make it easier to run the tube into the fill hole, I removed the air intake snorkel over the radiator. The downward angle of the fill hole makes it appear that filling is a problem but actually it worked out quite well. I had my car up on the Rhino ramps when i did the job.

After filling my transmission with Red Line MT-90, the stick moves like an eel in oil. Definitely a worthwhile mod.

I just finised too, man, pretty easy, except at first I was using a small as hell tube and it was slow as hell to go in, but got a bigger one and no big problem. ***** nice now, mush better then before, but then again I had a **** load of chips come out wiht the old oil, and it was a metelic color, oh well, the transmision still works. . Used the same mobile synthetic oil. We'll see how long the shift quality lasts, I just had to go out and drive today, the gear shifts actually felt nice, I'd say this feels better then a cable shift system, but then again, I had **** for oil before the change.

The only thing is that oil really stinks, really.

A mean trick to play is have buddy with ya and dab a little behind his ear it will keep the ladies away for a while that smell seems to stick even after you scrub up. I can come home from work and my wife will say " you where at gear oil weren't you" everytime I take a gearbox apart.

Stinky stuff

Oh yeah, that gear oil stinks, even just out of the bottle.

I really didn't notice much difference in shift quality, but then again I was just doing it for general purpose. I just bought the car and want all the fluids changed as soon as practical just to know for sure it was done. The best news I got was that the magnets had just the barest hint of fine powder on them. That tranny is in FINE shape. Which was the other reason for changing the fluid. I couldn't find out waht sahpe the tranny was in any other way.

Could some one try to explain this to me rationally.

I poured out the old oil, pourd in 2.8 quarts of the new, after tightening the drain bolt of course, tightened the fill bolt. Car ran amazing last night, it wasn't as sluggish as before, it was more laive, gears changed beautifully and all, same this moring, car had no problems running and going it was like it had a new life and gears changed like a dream. It was nice and cool, 60ish last night and this morning. After work, and the car standing on the lot for like 11 hours in direct daylight when it was ligke 80 at most, driving back from work to see some houses it was going normally far a while, then I was accelerating and the thing had no go, even after pressing the gas harder, I thought it was the up hill, but the same thing down hill afterwards. Holding the gas down slightly to go 50 in 5th gear as usual resaulted in the engin working hard and bearly hitting 40. And now shifitng gears is like major ***. You can feel it snapping in, like there was no lubrication what so ever. It's rough and very unatural, much worst then it has ever been. Right before this I noticed that on one upshift from first to second on the way there I could feel the actualy gear teeth slipping, no noise though, just a jump in gears as if they missed, my dad was driving as a passeneger and when I told him that I felt the gears slipped he said he didn't hear ****. And if you think it's me that says the car slows down, then, my dad who thinks my car is **** and doesn't care much for it, he could care less if it was slow or not (can't blame him he doesn't like sticks any more and doesn't want to admit it's a pretty nice car for the year and price), was the first ot mention how badly the car lost power. I felt it but didn't say anything he just says, did you notice how badly the car lost power?

I'm shocked, how in the world would changing oil mess up my ride so bad. I'm not in the market for a new transmision, that or this oil (mobile 1) is major ****. I doubt it could be my fault, as I onyl changed the oil, and it did run amazing for a short while. Now I have to find a way to get back the money I spent on this ****. considering I throught the bottles and can't find the reciept, damit. Stupid autozone.

BTW, when I filled the car, I noiticed some sediments in two bottles at the bottom, didn't make anything of it, would that have anything to do with it?

Any advice???

Are you sure?

Sounds like 1 of 3 things - you didn't tighten the bolt down enough and now you have no fluid, you're clutch is going out, or you have an unrrelated engine problem, maybe in your ignition. It sounds more like the clutch is slipping, or you have an unrelated engine problem, although the time elapsed after you filled the sump and the problems you are having suggests that maybe you ran out of fluid. I hate to say, but maybe you need to drain the transaxle again, just to make sure there's fluid in there. I hope so, your transmission may have been ruined.
