Ford wants $350 - 500 for this repair on my son's 2010 F-150 5.4 with 93K miles

Difficulty: Easier and less messy than changing transmission oil the old way.

Parts: Transmission CAN connect sleeve $22.04 (Ford counter man knows this part by memory)
Up to 10 qts of Valvoline max life recommended for Mercon LV
Filter and pan gasket NAPA $85

Tools: Plastic concrete mixing pan Home Depot
Modified 1 gallon Pump up bleach sprayer with Viton seals $16 Home depot
3/4" or 19mm end wrench 1/4 drive 8mm socket, rachet, 4" extension and 1/4" torque wrench.
Brake bleed vacuum kit with a 3/16 ID hose to siphon fluid out of pan

Observations: Fluid was dirty and needed to be changed. Pan was clean no wear debris in bottom.

20/20 hindsight: Ford says you can resuse the pan gasket. It looks to be 2 pieces of aluminum strips held to together with very thin bead of formed RTV . Very flimsey and if I were using $10 qt synthetic I would not risk it resealing. Next change I will use a top quality formed rubber gasket (NAPA).

This is where the transmission was leaking. It had been slowly leaking for sometime. I noticed a big puddle under the truck parking it up hill after 100 mile trip.

A picture of the "dip stick"

I inserted a rubber vacuum hose down the the dipstick hole and used my vacuum brake bleeder to start the siphon. It took about 3.5 hours to get about 6 quarts in the drain pan. If you you do not drain this way you will have fluid from the pan land on the crossmember and spread out everywhere creating a big mess.

NOTE: Use care. mineral oil can damage brake seals. It will cause them swell. Clean out out all transmission fluid from the cup and hoses before reusing.

Here is the connector sleeve, New one has a black O rings old had red, typical VITON color( "FKM" generic abreviation). Viton of FKM is about the seal material you can use for this application.

Next you remove the exterior male connector by twisting connector lever counterclock wise. Near the valve body, push the white plastic retainer catch out of the way and pull it down.

Remove the old connector sleeve, lube the new one with transmission oil. Insert light and turn until you feel the oreintation rib then press the rest of the way moderate pressure is required to full seat. If it is not seated the white retainer can not be pushed back up.

Pic of the modifed sparyer for adding the transmission fluid. I added 6 quarts before starting the engine to add another 4 quarts! I did take some to accomplish. My son pumped it up while I filled. The material feed tube inside the sprayer is amaller diameter and will not allow a large volume of fluid pass through it.

NOTE: Make sure the dips stick fully seats to check fluid. I filed about 1/2" below the hash line to allow for vehicle angle on jackstands fluid not being warm as Ford recommends.

Observation: Amazing how fast you get use to checking fluid level and avoiding the hot catalytic converter!

I see the connector in the picture, but where is it located on the trans? Top, side,bottom? My 09 has leaked for years very slowly and I want to fix this ASAP.
