Any engine needs to running, and at normal operating temperature, before ever checking the Transmission Fluid level. Checking this fluid without the engine running will give false readings indicating a full reservoir, when in fact if running, may not even be half full in some instances.
Equally as bad as a half full transmission is one that is overfilled - too much of a good thing will also kill the transmission.
Check transmission fluid level Change transmission fluid and filter
A 2000 Mercury Sable might have a vibration at low speeds after changing the transmission fluid because of a lack of fluid or leaking fluid. Check the transmission case for leakage and check the fluid level before driving again.
The Mercury Sable transmission has a fluid capacity of 12 quarts. You can use any SAE certified automatic transmission fluid.
Mine did the same.it was low on transmission fluid..i would check that because I filled it back up and it was running so much better.
Clean the 1994 Sable transmission at a car wash. This will make it easier to find the leak. Keeping the fluid full, check the transmission frequently to see where the leak is.
Check under where the brake fluid goes its hard to get too and you will need a long spouted funnel
According to the 2000 Mercury Sable Owner Guide : ( Motorcraft MERCON - V , automatic transmission fluid in both types of automatic transaxle / transmission )
According to the 1999 Mercury Sable Owner Guide : ( Motorcraft MERCON-V automatic transmission fluid ) ( to confirm the type used , it should be engraved in the automatic transmission fluid dipstick )
According to the 1998 Mercury Sable Owner Guide : ( Motorcraft MERCON-V automatic transmission fluid )
Mercon V
On a 2001 Mercury Sable : The automatic transaxle ( transmission ) fluid level dipstick is near the firewall , in the area of the brake fluid reservoir , in the engine compartment
I believe the type used is engraved into the transmission ( transaxle ) fluid level dipstick
