This is new for Ford but not new to the industry. VW has been doing it for years.
Can you tell us about how the 5R55S is different? I'd sure like to know. And are the seals really that much better than before or is the intention to replace as soon as a leak begins? Thanks.

slipping at 51000

So I guess since my 05 mustang 4.0, 51,000 miles, auto trans is slipping, I'm screwed. Every GM that I had just needed fluid checked and never did anything else with them. 1) Chevy 179000 miles. 2)Chevy 119000 miles. 3) Chevy 109000 miles. All were traded in and in good running condition. Good job FORD Guess that I'll wait until the end of the month and see what my GM dealer is up to. Needs tires and transmission fluid, time to trade it in! :hihi: Just a side note, my current GM has 51,500 and has no problems.

its probably just low on fluid. you should take it in and get it flushed. that way they can replace 12 qts of fluid, vs, 5 qts if you drop the pan. they do have a filter, but its not really filter media, just a screen. you wont need to replace the filter. they recomend the filter at 100,00+. checking the fluid was described earlier in the post and yes, it is messy to check. with the motor runing at operating temp, you pull that bottom plug, if it doesnt spew out, its low on fluid. you can pump fluid up into it till it does spew, then its full.

Please correct me if I'm wrong.... Spoke w/a dealer mechanic yesterday and they explained the removal of the center plug, squirting fluid in until it returns out for proper level, HOWEVER he never mentioned the car should be running...?? This should be checked with the car at operating temps and RUNNING?

With the engine running.


From the Ford Factory Service Manual:

1. Using the diagnostic tool, monitor the transmission fluid temperature (TFT) using PID: TFT.

2. Start the vehicle.

3. NOTE: Engine idle speed is approximately 650 rpm.
While proceeding with this procedure, run the engine until the transmission fluid temperature is between 27-49C (80-120F).

4. Move the range selector lever slowly through each gear, stopping in each position and allowing the transmission to engage.

5. Place the range selector lever in the PARK position.

6. With the engine running, position the vehicle on a hoist and set it as close to level as possible. For additional information, refer to Section 100-02 .

7. Hold the larger drain plug with a wrench and remove the small (center) fluid level indicating plug.

8. Install the special tool into the pan.

9. NOTE: Prior to filling the special tool with clean transmission fluid, make sure that the canister is clean.


Fill the special tool with clean automatic transmission fluid.

10. Hang the special tool under the vehicle. Position it upright and close to the transmission.


11. Connect the special tools.
  • Connect the open end of the fluid hose from the Fluid Transporter/Evacuator/Injector to the Fluid Level and Fill Plug Adapter at the bottom of the transmission fluid pan.
12. Apply a maximum of 206.85 kPa (30 psi) to the open end of the vacuum/pressure hose from the special tool. Fluid will immediately start flowing out of the special tool into the transmission fluid pan.

13. Add one pint of transmission fluid into the fluid pan. Stop the process by releasing the air pressure and removing the air nozzle from the end of the hose.

14. Inspect the fluid level in the special tool. If the fluid drains back into the canister, the transmission is full. If no fluid drains back, more fluid will need to be added. Repeat Steps 12 and 13.

15. Once the transmission is full, place a hand vacuum pump on the open end of the vacuum/pressure hose of the special tool and apply vacuum to the system. This will pull out any extra fluid trapped in the system and direct it into the container.

16. Allow the fluid to drain. Make sure that the fluid temperature is between 27-49C (80-120F). When the fluid comes out as a thin stream or drip, the fluid is at the correct level.

17. Reinstall the small (center) fluid level indicating plug and tighten to 10 Nm (89 lb-in).

18. Check the operation of the transmission by moving the range selector lever slowly through each gear, stopping in each position and allowing the transmission to engage.

Not ready to lay down with this one yet... Have an idea. Does anyone have or maybe a link to a picture of this "tube" inside our pan? When we remove the larger-drain plug, is the tube attached to the otherside?

You're quite welcome.

Three images are attached below. The first is a diagram from the Ford Factory Service Manual. The second is the plug on the outside of the pan, and the third is an actual picture of the plug inside the pan.

What is your concern? Do you just want to check the level? The drain plug assembly is a concentric plug inside a plug (see second picture). The internal plug is basically a Torx set screw. That is the one you want to remove while holding the outer plug with a wrench. If you remove that internal plug and fluid streams out under the above conditions I posted, you are all set, and just re-install the plug.

If no fluid comes out, then you can purchase a hand pump that threads onto a quart bottle of transmission fluid at most autoparts stores or even Walmart. Lubrimatic / Plews makes one. Here is an example:

"Lubrimatic" Fluid Quart Pump

I beleive the internal plug hole (Torx screw) is threaded with a female 1/8" NPT fitting, but you should confirm that. You will need to purchase an 1/8" NPT brass nipple at a local hardware store, Home Depot, or Lowes in the plumbing section. Connect this nipple to the end of the hose that comes with the hand pump and thread the other end into the hole where you removed the Torx plug. You will be good to go. Pump in a little fluid, stop, remove the hose and see if any fluid streams out. Continue until it starts to stream out. Re-install the Torx plug and you are done.
