ATF Fluid Change in 98 F150

[Ford_Racing_Guy]

I plan to change all the fluid in my dad's truck tomorrow.

now i ran searches and couldn't find any thing about draining the torque converter and whatnot, most results said that stock converters don't have drains and stuff, but if his does and i do drain all the fluid including the pan, do i have to do anything special while filling it up because it will be bone-dry?


or do i just fill dump 4 to 5 quarts in, start it, dump more in and just keep checking it until the converter fills up?


if all else fails and there is no plug, then i'll just flush out with the cooler lines.

the convertor will not drain with a pan drop.. the only way to evacuate that fluid is either remove the tranny and tc from the vehicle and bench drain it, or have the system power flushed... there are ways to do the power flushing yourself though... i am not sure o nthe proceudre myself as i would jsut take it somewhere and not need to worry about messing anything up...

I would recommend getting it flush and serviced at a shop. Transmissions are easy to do, when you have the right equipment -- The flush machine we use is BGs and it works really well. We usually hook up around the radiator/cooler and then start it up and let it exchange fluid. Now, to do this in a driveway is a little harder without the machine -- I do not know the procedure, but there may be one on here somewhere. Otherwise, changethe filter and the 5quarts is the best you can probably do. Good luck.

Oh, and I'm sure it's Mercon 5 (the synthetic) -- most Fords are now.

There is NO reason to pay someone to flush a transmission. Its a 15 minute job for the DIYer.

Good luck ....

If the f-150 has a 4r70w the torque convertor will probably have a drain plug.

The following is how I flush mine:

It is best to drop the pan ( at least once ) and change the filter, Refill with ATF of your choice and then do the following flush procedure:

I disconnected the "to transmission" hose from my remote filter housing. I plugged and clamped the disconnected line and added and hose clamped a 6 ft length of 3/8? line to the housing. The other end went into a calibrated water jug ( 1 gal size ).

The the truck run at idle while 1 quart is pumped out. Stop the truck andd add back 1 quart of new ATF.

We used 15 quarts of Amsoil ATF.

Even though this ATF ( Amsoil ) has about 50 k miles on it, it still looked remarkably good, just slightly darker in color.

After the flush/fill was completed, I added a new K & N filter to the housing and reattached the hoses.

The procedure took my son and I about 15 minutes to complete. There was no mess since we were well prepared for the flush; nary a drop was spilled.

well it did have the plug on the converter so i drained all of the fluid, dropped the pan replaced the filter filled it up and it shifts great now.

also change the fluid in the Transfer case and that was darker

so now it has clean fluid all around. easy job done except that they gave my dad the wrong filter kit at Advanced so I had to run back and exchange it.

Sure someone can answere (chris?) some models do have a drain plug on the converter
which ones?

Most all of the older transmissions have TC plugs. I have just heard of quite a few later models that do not. It seems to be very rare on the new stuff Ford is making. Regards,
