SOURCE: Where is the transmission fluid drain plug for a 2000 Cougar

Your Ford has no drain plug, to change/drain the trans fluid u must remove the transmission pan, u may be able to lower fluid level with a fluid siphon pump (rated for oil) through the dipstick tube, harbor freight tools sells a pump for this purpose.

SOURCE: cougar 2000 leaks transmition fluid through dipstick.

Check the level and make sure it wasn't overfilled. (running, hot and in park) If the level is ok, look for the vent. It should be on top of the trans, maybe by the linkage. It should be covered by either a metal or rubber cap. That may be clogged.

SOURCE: 1999 mercury cougar transmission problem i dont understand

This is being caused by the seals in the transmission worn out and the heat is causing them to become to plyable thus losing pressure, an overhual is needed

Why does it kicks at 40mph


Sounds like it could be going into overdrive or locking up the clutch in the t-r-a-nsmission. Go get some SEA FOAM t-r-a-nsmission treatment and add it and run it thru the gears and drive it around.IF the fluid needs replaced,then do it after doing this. don-ohio (:^)

Transmission over drive is causing the transmission to slip. When I take off the overdrive the transmission functions normally but it uses much more gas.


Roger, that doesn't even make a whole lot of sense to me. If the overdrive is causing the transmission to slip, wouldn't it also cause the fuel mileage to go down? Are you sure the transmission is slipping? Or is the transmission simply shifting in and out of overdrive? If it is, is it shifting at the proper speeds? Driving at around 40 - 50 Mph will sometimes make the transmission go in and out of overdrive repeatedly. This can be perfectly normal.

Have you checked your transmission fluid level?

Is your overdrive off light flashing? If the transmission is actually slipping the OD OFF light should be blinking at you to let you know there is a transmission problem. Either that, or the Check Engine light will be coming on. In either of these cases, you need to scan your onboard computer network for possible fault codes.

It started about one week ago my 96 mercury cougar XR7 won't go over 35 mph it just revs to about 3000 rpm. I replaced the pcv and had a complete tune-up, also checked the transmission. What could...


If it revs up & doesn't go,the trans is slipping
& will have to be rebuilt

Not going over 35 with no trans issues would
be a bad exhaust converter (blocked) & or
a clogged gas filter

Tune-up is sort of a outdated term and never
is a cure for much ,unless you have ignition issues

Never have to replace any PCV Valves. Remove & clean
every 3 years

1988 mercury cougar 3.8 wont shift out of second gear into 3rd or overdrive. Have tried to disconnect shift cable (kick down cable) but no help there.


Your problem is in the transmission. There are a number of things that could cause this but typically start by checking the fluid level, if that is good do a fluid and filter change. If that fails to correct the problem or you find a lot of metal in the pan, it will look like a gray goo in the bottom of the pan, have the transmission rebuilt and repaired.

Where does the transmission fluid go in a 1991 mercury cougar


If you need to add fluid, just pour it in the tube that the transmission dipstick is in. Be sure to check it when the transmission fluid is fully warmed up and DO NOT overfill.

My 2002 trailblazer is making a noise when I go over 45 mph and appears to not be going in gear quickly at that speed


Check your transmission fluid level and/or have the fluid changed. If problem persist have a transmission professional at a dealership or transmission shop service it.
