According to the 2000 Mercury Sable Owner Guide : That is your check trans-axle ( transmission ) warning light that is located in the bottom / left area of your tachometer ( a problem has been detected , shifting may be restricted ) ( if warning lamp remains on , have your vehicle serviced immediately )
The trans axle is the transmission on a front wheel drive vehicle

The transaxle is the transmission on a front wheel drive car , it's bolted to the engine ( looking in the engine compartment from the front the transaxle is to the right of the engine )
The axle retainer nut is likely to be the same as on the 1998: 30mm
Bolts by the starter(2 on starter) and 5 or 6 around the transmission housing and 2 up by the front of the motor near the axle for the passenger side front wheel where you can't see them.
Alot of things can cause this as a week mount a wore out CV axle and pressure
A Nissan Altima with a cracked axle. Meaning the part that connects your tire to the transmission is broken....
It's on the top rear corner of the transmission.
It is easier and cheaper to replace the entire axle. About $80.
I have a 97 and assume it is in the same location. Open the hood. Stand at the drivers side fender and look straight down to the transmission. It should be located just to the rear of where the CV-Shaft comes out of the transmission - in the vacinity of the motor mount.
