Where is the transmission dipstick located on a 1986 Mercury Grand Marquis?
Look at the back of the eng. by the firewall on the passengers side, it should say TRANS on the handle
On a 1989 Mercury Grand Marquis : The automatic transmission fluid level dipstick should be in the engine compartment , near the firewall ( the metal wall that divides the engine compartment from the passenger compartment ) just towards the passenger side of the vehicle ( where the rear of the engine connects to the transmission )
On a 1998 Mercury Mountaineer : Using a funnel , add the automatic transmission fluid through the automatic transmission fluid dipstick tube . It is located near the firewall , just to the right side ( passenger side ) of the engine , where the transmission is bolted to the rear of the engine . ( the type of transmission fluid to use should be engraved into the dipstick )
