    Hi everyone.

    While doing my clutch swap I had to drain the transmission, but I had a lot of trouble getting the speedometer mount off to refill it.

    So instead, I filled it from the bottom. Here's how:

    1. Go to your local hardware store, and buy a 1/2" screw-to-hose adapter. One side bolts into the tranny (in the oil plug hole), and the other side attaches to a hose. It's hollow, allowing oil to flow through it. Then, buy a 1/2" hose, preferably 8' long, and a funnel with a spout small enough to fit in the hose. Finally, buy a roll of duct tape. :)

    2. Plug the funnel into one end of the hose, and secure it with duct tape.

    3. Remove the transmission drain plug (23mm or 7/8"; careful not to strip it), and drain the oil into a pan. Let it run until the dripping completely stops. Preferably do it while the transmission is warm, but not hot.

    4. Screw the bolt end of the adapter into the drain plug hole. It won't be a perfect fit, so do it tightly enough that the gasket mates with the transmission housing to minimize leaking. Attach the other end of the hose to the adapter.

    5. Measure out approximately 3 liters (3.3 qts) of Dexron III/Mercon ATF fluid or 80/90 gear oil, and pour it slowly into the funnel, while holding it 6' from the ground. Either add it a bit at a time and raise it above your head (to create pressure), or stand on something. Once all the fluid is it, the transmission is slightly overfilled. This is fine, since in the next step, some of this fluid will escape.

    6. Hook the funnel onto something 3-4' off the ground (to prevent the transmission fluid from spilling out), and reposition the oil pan under the drain hole. Have the drain plug and some towels nearby. Then, quickly remove the hose by pulling it, and plug the hole with your finger. It will get messy. :)

    7. Unscrew the adapter with your finger over the hose hole. When it breaks free, let it drop, and plug the drain hole with your finger.

    8. Slide your finger out of the way while inserting the original drain plug. Tighten, clean up, and you're done!

    thats a good idea... but once you get the spedo vss out it is 10x easier than that and you dont make a mess. i understand if you dont really know what your doing and you cannot get the thing out sure but after you figure it out the first time its super simple and way easy.

    I couldnt ever get mine out... I filled mine this way through the reverse sensor. If i ever have to swap trannies, Im drilling and tapping a hole for a fill plug. And if i ever meet the asshole that designed that tranny without a fill plug, im gonna kick him in the junk.

    Well, I pried at that bastard for a good hour with no luck. I couldn't see it very well because I'd already reinstalled my tranny, and that didn't help. But, this saved my ass. :)

    My tranny has two plugs, one to drain it and one higher up to fill it. Anyone else have this?

    I've been tempted a few times to fill'em back up this way.
    Those speedo sensor can really get stuck. I've had to destroy one to get it free.

    WRONG... both the ATX and MTX use Dex/Merc III

    Why the problem?

    Why is everyone having such a problem filling the gen 2 5 speeds? Put a socket on a bunch of extentions to remove the screw holding the speedo feed bracket into the tranny, and set that screw aside. Stick a set of VICE GRIPS down there and lightly clamp them on as low as you can to the thing (as close to the tranny as possible). Just wiggle it back and forth a few times, then everything will come out as one big unit. When you put it back it, you may have to wiggle it in or tap it with a flathead screwdriver and hammer. Both work pretty well, but I've found you get a better seal if you make it go all the way back down just by turning it.

    And what if it doesn't, like mine did?

    Exactly... Getting the retainer bracket off was easy, but I pulled at the housing for a good hour and ended up busting off pieces of the ring that sticks up. It was in there good. :(

    twist it... if you remove the spedo cable then you can twist the whole assembly and that will help... it will come.

    Take an aluminum tranny case case, a steel speedo sensor housing and mix under heat for 50k+ miles and see if theres a chemical reaction! :wink:

    Hurray for double posts! I guess I've just been lucky on all the 'scorts I've worked on. They always come out for me - never been able to pull one out by hand though, I've ALWAYS used the vice grips.

    I'd be more interested in a how to drain an automatic completely (including torque converter) and refill. The service manual only tells you how to drop the pan and do a fluid and filter change. To drain the torque converter it says to disconnect the cooler and connect it to a machine that does the flushing. Like I can do that at home.

    i've done clutches on both an LX and a GT and i've had major troubles with both. i've never been able to pull the things out with a pair of vice grips.. i just usually drop the tranny then let my engineer dad have a go at it.. ;) lol, or maybe it's just the climate in ontario or something. oh well.. just my 2 cents.
