How To: Transmission Fluid Drain And Refill

This is being done on a 1999 Ford Ranger 4x4 4.0 OHV

The tools you will need for this job are a:

3/8" socket wrench
3/8" socket extension
3/8" Bendable socket extension
13mm socket
Large drain pain
scraper
RTV
A long and narrow funnel
Brake clean

If you have a creeper it helps out alot.

You will need 5 quarts of Transmission fluid preferably Valvoline Max life Dex/Merc Transmission fluid. You will also need to purchase the Filter kit which comes with the filter, necessary O-rings, bolt and fresh seal for the transmission pan. I purchased all of this at my local auto parts store.

Step one: Put your truck where you want to work on it and put it in park. Use Jack and Jack stands if necessary.

Step two: Remove the clips of the shield that is located on the passenger side in between the transmission pan and Catalytic converter and move it up and out of the way.

Step three: Start taking out the bolts along the sides of the pan.

leave 2 bolts on each end of the pan on for now.

Rear of pan


Step four: You want to drain the fluid from the rear of the pan. Make sure you have your Drain pan in place. To do this Loosen the 2 rear bolts a couple turns. Then go ahead and loosen the front 2 bolts a couple less turns than the rear, this way the pan will start to tilt towards the rear so the fluid will come out on one side. You may have to get a screwdriver and pry between the pan and the transmission to release the seal for the fluid to really begin to come out. Now continue to loosen the rear bolts and the front 2 bolts until the majority of the fluid is out.

Step five: Drop the Pan and dump any remaining fluid in the drain pain.

Step six: Take off the old seal

scrape any remaining pieces so that the surface is clean of the old seal.

Now take the bottle of Brake clean and spray the inside of the pan clean

Step seven: Take out your new seal. To keep the seal from moving around while you try to bolt the pan back up, spread a little bit of RTV around the pan. Place the seal on the pan, make sure all the holes line up with the holes in the seal, go around and press down on the seal to make sure that the seal is in place properly.

Step eight: Unbolt the Transmission filter.

My old filter used a 10mm bolt while my new filter used a 8mm bolt so just look and see what yours may need.

Step nine: When taking the filter off, make sure you still have the Drain pain in place under the Transmission because there is still some trapped fluid behind the filter. When the filter is off make sure the 2 O-rings are still attached to the open circles of the filter as so

Step ten: Make sure to put the New O-rings that come with the kit in place on the new filter

Step eleven: Put everything back in, in reverse order. Torque bolts to proper specification.

Step twelve: Put fluid in accordingly. I put 4 and a half quarts in and then went through the gears to properly check the fluid level.

Good Luck! I hope this helps.

Since it came up in another thread I though I'd add this in:

If you have a 2wd with the 5R55E / 5R44E you can swap in the filter and pan from a 4wd and gain a little bit of capacity with a better design.

Thanks. I've never heard of that but its a good point to keep in mind if you have those specs.

This procedure is good, but it should be noted that it only replaces the filter and about 4 to 5 quarts of fluid. The torque converter holds a bunch, so on start up, the fresh 4 to 5 quarts will soon mix with the old fluid still held in the torque converter. A true "flush" (that gets all the fluid changed) can only be done at a shop that has a flushing device.

This however is still a good way to get some needed additives into old "stale" transmission fluid. If this is done every 30K, the transmission will last much longer.

For regular maintenance a drain and refill is what you want and what is recommended by the manufacturer, not a full flush.
