Show me a picture of where the transmission fluid goes in a 2003 Mercury Mountaineer please

it has a plug on the bottom of transmission, fyi I believe there's a recall for leaking transmission lines on your so have the dealer take care of it for free

P0775 FORD - Pressure Control Solenoid B Malfunction Possible causes - Faulty line pressure solenoid B valve
- Line pressure solenoid B valve harness or connectors
- Line pressure solenoid B valve circuit is open or shorted
- Low transmission fluid level
- Dirty transmission fluid Hope this helps...

if you need to add tranny fluid just pour it in where the dipstick goes. but first make sure to check it while it is hot so you don't over-fill. you really don't won't that with that ford. depending on what your problem is you may not need fluid, just a tranny filter. hope this helps

Automatic Transmission uses MERCON V ATF, 12.7quarts.

Transfer Case uses MERCON ATF, AWD 1.25 quarts, 4 wheel drive 1.4 quarts.

Source Ford owners manual.

First thing is to check the transmission fluid. If the fluid level is good - have it checked by a transmission shop. Give them as much info as you can about when it slips - cold, climbing hills, going from second to high gear, etc.

2003 does not have a dipstick. I just checked my owners manual. The local mechanic said transmission fluid changes have to be done at the dealer.

you have torque converter back flowm seen it a million times...

A hydraulic retarder and control composed of an accumulator, for rapid filling of the retarder; a pulse valve, for controlling fluid flow to and from the accumulator; a regulator valve, for limiting the inlet pressure to the retarder; and a pair of check valves, for preventing fluid flow from the retarder to a pressure source and from the retarder to the accumulator. The pulse valve is controllable to provide rapid filling of the retarder, while the regulator valve will direct fluid from a secondary source to the retarder and control the pressure at the retarder inlet. The accumulator is filled from the main pressure source, between ****** requests, at a rate that does not disturb the main transmission pressure level. One of the check valves and the pulse valve prevent the fluid in the accumulator from returning to the system other than when a ****** request is present.

It does not have a dipstick.To check the fluid trans fluid has to be warm then you take the allen screw out of plug in pan, see 1st pick and you should have a steady drip from the hole. If you have to add fluid you would need the special tool shown in second pick and a tool to pump fluid in.

if it is a manual transmission you have to check it from under the car by opening the fill plug. if fluid starts flowing out your full if not than you need to service it.

if it is an automatic it will be close to the firewall and hard to spot. but it is there. if you have 45,000 miles on it you should have the transmission serviced whether it is an automatic or manual.
