Take it easy and slowly work the truck back and forward. What usually happens is that the pan seal starts to go south and you'll likely see a dirty pan from fluid leakage. The trans has been behaving since that one incident that started all of this. When I droped the pan a yellow top lookinf piece fell out and I would like to know where it goes. When the oil breaks down it tends to find ways out. A quart of tranny fluid at 93,000 miles isnt eyebrow raising amounts of fluid lost. Wanted to run this one past y'all.
Get under the truck and leave the vinyl hose connected, but move it out of the way. The fluid was initially a slightly darker red. This will allow the new fluid to cycle through the system. Topped it up with 2qt of fluid and tracer dye. But all-but-bone-dry when hot and up to operating temps? I know you said you added the pint and later it went low but trust me you probably didnt lose what you think you did. Position the bucket so that you can easily see the quart markings point the markings toward the driver side if you are working solo. Going to take it to a mechanic to have the plugs changed.
If you can get a helper person, you can probably finish in 2 hours. There are myriad web pages on the internet for servicing the 4R70W, as it is the automatic transmission commonly used in Mustangs and in Crown Victorias, but very few resources when it comes to servicing the transmission in a truck. On my vehicle, almost exactly 4 quarts was extracted before I started to notice air bubbles in the vinyl line. Certainly not fresh fluid red. Remove all the bolts but one around the drain pan and wait for the fluid to stop running into the pan.
Wash the drain pan and bolt. You should be familiar with the terms used in this writeup and understand what is meant when direction is specified on a vehicle forward, rear, driver-side, passenger-side, etc. Tip the remainder of the fluid into the drain pan. I would try not to extract more than 3 quarts at a time. But enough to grab my attention.
If you can't find a transmission dipstick any where in the Nubira engine chamber, then it'll be electronically controlled. The filter may or may not drop along with the pan. That's what every ford i have owned since 1981 has required for the transfer case. The 2002 Ford Ranger requires a transmission fluid change every two years or 30,000 miles. You may just need a new pan seal.
The maintenance requires only a few tools and about an hour. The way the the system keep transmission fluid from going into the transfer case is a seal on the front of the transfer case. Why would it be over flowing when cold? It is the 14 bolt pan not the 20 and is a 5. Going to have a pro change them out for me. If you use Royal Purple 75W-140 axle lube, the modifier is not needed.
Also wipe the dip stick on a white rag and note the colour and smell. But its always good to give these f series trannies a bit of love. The transmission fluid will fill the bucket quickly, so keep an active eye on when you begin seeing bubbles in the vinyl line, as this indicates that the bulk of the transmission fluid has been sucked out of the transmission pan. Its either going to leave a trail on the outside, or it is migrating elsewhere, which is past the rear seal into the transfer case. That's why you are supposed to only check when the car is running. Allow the excess tubing to hang down to the ground and cut the tubing where it meets the ground.
I was personally frustrated with the lack of any useful information on performing the fluid change procedure, so I researched and researched and put together this guide. Not good, but no harm done. I think I had around. You can always use the rest later for other automotive maintenance procedures. This saves some time at the end of the procedure. Damn near bone dry again.
E an approx 1in stem on a small barrel with an o-ring on the barrel. Didn't find any external leaks. Please excuse the crudeness of my drawing Basically, the transmission utilizes a closed-loop cooling system where the transmission fluid is pumped forward of the vehicle to the radiator where it is cooled via the engine fan and airflow when driving down the road. Immediately, look below the truck at the bucket and wait for the transmission fluid to begin flowing. Engine just purrs now and has some power back. The answers is the thread size for the oil drain plug on a 7. About a month ago, I noticed the transmission acting wonky.
