It is on the drivers side, near the top, a little bit forward of the linkage.
On an A/T it is the check/fill dipstick. On a manual, it is located on the top of the trans.
The vent hose is for either the transfer case breather or the transmission breather. A light amount of oil residue is normal. If there is a lot of fluid coming out of the hose then it is most likely caused from the transmission getting too hot.
Assuming you mean transmission vent: 1) Excessively high fluid level. 2) Tube has hose incorrectly located.
It depends on the year, for Cougars made from '99 till '02, the Automatic Transmission Breather hose is located on the drivers side of the engine, underneath the battery tray.
The Automatic transmission breather tube is on the drivers side of the vehicle and is under the air filter box under the hood, it often reaches up near the battery tray.
Allow pressurized gases to vent from the crankcase.
Sounds like a vent problem. Check the breather on top of the case to see if it's blocked.
The breather vent for the AX5 is located on the top front of the shift tower. Remove the rubber shift lever boot to expose the vent from above. It appears as a small metal cap about 3/4"tall and should spin freely.
the A/T vents are on top of the tranny, and go to a high water vent tube highcenter on the fire wall, (ive overhauld 3 sidekicks ground up)here is proof.in fact the 4wd has 2 tubes on top merging to 1 tube and a breather. cap.you can go underwater deep and not get water in to this breather.the 3 speed, see it?http://www.fixkick.com/tranny/3L30/3L30right.jpgthe 4 speed, see them across the top?http://www.fixkick.com/tranny/3L30/3L30right.jpgtell transmission speed 3 and 4 , and can show any part.The vent hole for an A/T is the dipstick tube.
breather vent on top of tyranny is open to air the only vacuum hose that's hooked up is shift modulator to constant vacuum on manifold
