I was changing my oil yesterday, and like a moron, I undid the wrong bolt and drained half of my transmission fluid. So I bought some new fluid, and I can't figure out how to get it in. I have a 5 speed manual transmission, and I got my entire trany rebuilt in December, so all I need to do is fill it back up. I don't have an owner's manual. Can you help me fing the fill port?
Thanks!

It should be a bolt on the side of the tranny that you fill it through. The bolt should be on the side of the tranny facing the front of the car.

Is the bolt vertical or pointed at the grill? Is it right at the top, like the oil, or is it a good arm distance down in there? Any idea on the approximate size of the bolt so I can feel confident I've found the right one?

It should be a 23mm bolt it sort of faces towards the ground (angled) but its on the side of the tranny facing the front of the car you should be able to see this bolt if you lift the car, it looks exactly as the drain one that you took out earlier but just higher in the tranny.

Reading other treads led me to this: It was the 23 mm bolt I loosened that drained the tranny fluid on the bottom. In my 94 protege, the fill port is 16mm, whereas in the newer ones, the fill port is 23mm. Anyway, I just opened that fill port and liquid started coming out of that too! After losing 2 oz I screwed it back in... How can fluid come out both ends?! What scares me more is that the fluid that came out the lower hole was thick and red. The liquid that just came out what I thought was the fill port was thin and had a greenish tint. Did I just tap into a different resevoir completely? I had the transmission replaced completely my Aamco half a year ago... If fluid comes out, how can I force fluid in? I lost 1-2 quarts of the red fluid, so I need to fill it back in somehow! The 75W90 synthetic gear oil I bought is brown like regular engine oil. Does the red vs brown color matter and can they be mixed? I also remember the guy at Aamco saying something about my manual transmission fluid is held under pressure... What concerns and precautions should I take to ensure that I don't mess this up... I don't want a $1500 mistake here...

Here is what you should do is contact your dealer and see how many quarts of tranny fluid your car takes. I have a 2000 and it took 3.9 quarts if I am not mistaken, when I changed it last month. Anyways if you did find the tranny fill and it poured out of it then it was overfilled because in most cases the fluid is full when it is even with the threads of the fill hole. But what you should do is after finding out how many quarts I would just drain the whole thing and refill it with what ever synthetic fluid you want just to be on the safe side. Maybe someone else on here might have another idea also.

If you have a 94 protege, you should be filling your tranny through your speedo gear hole. there is a 10mm bolt that holds it in. its on the back side of the tranny. you get to it from the top. your tranny takes 3.2qts.

Unscrew your speedo-cable and here's what you'll see...


Take out the 10mm bolt and remove this piece...



You fill your tranny here.


Questions?

we have tranny fluid? lol, thats only for auto tranny though right?

CorkSport.com

The 5speed has fluid also. and is filled in the same spot.

lukasz70

um is their a dipstick to check it by any chance or is it just in their? cause i thought manual tranny doesn't need fluid cause what do you have in their? a clutch, flywheel... a bunch of other round things and those as far i know dont get covered in oil, i am just talking out of my *** though lol, but i can double check this with someone tomorrow

You have tranny oil to lubricate the gears. The speedo-gear is the dipstick, remove it and make sure the oil covers the red gear completely so you know you're full. You can use ATF in the manual gearbox, I use gear oil from AutoZone... personal preference.
