A pic would be great, because I don't think anybody knows what on Earth you're talking about.
I'm not trying to be a jerk, but are you sure you're looking at the drain plug, rather than 1.) the bolts that hold the two halves of the transmission together, or 2.) the bolts that hold the tranny to the engine?
Problem solved, the 2 "Plugs" are in fact part of the housing casting. They do have hex type heads but are not plugs. Poor lighting and failing close up vision are the problem. Sorry for the confussion and thanks for the attempted help. I see the correct plug for draining stashed up between the housing and mount. Thanks again.
Here's some pics from my SVT the layout should be similar.
This is the fill plug, this should be removed first. If you remove the drain plug first in the event that your car is driven in the salt belt the fill plug may be siezed. If this happens you will have removed the drain plug, drained all the fluid and now will have no way to replace it.
Next use a hex socket to remove the fill plug.
Then remove the drain plug and collect the fluid.
Here is the drain plug.
There are a few ways to fill the tranny back up. I used a funnel with a silicon hose going down through the engine compartment by the battery and coilpack. If the car is on jack stands or an un-level floor be careful not to overfill the tranny. Overfilling will generate a lot of heat and may damage a lot of expensive components.
The Focus has a transaxle, so the differential and transmission are combined into one unit. There's no separate differential to drain and fill like on rear- or all-wheel-drive.
I think all Foci with the MTX-75 need 2.1 quarts of fluid. I know the Ford spec is for the fluid to be within 5mm of the bottom of the fill hole. And, as was already mentioned, make sure you check the fluid with the vehicle level.
As for what fluid to use, our semi-resident guru, Terry Haines (KogboxKing) seems to like:
1.) Mobil 1 + Ford synthetic friction modifier
2.) Ford "honey" + friction modifier
The "honey" is XT-M5-QS, and the friction additive is XL-7. I think.
Thanks for the pictures, my tranny looks slightly different
but the point is clear.
I used the Motorcraft XT-M5-QS without any additional additives, shifts fine in all gears.However the slight fluttering sound that I've been told is gear rollover is still there.
