I just had my 2021 Ford Ranger XLT 4x4 serviced - Transmission Fluid Exchange and Brake Fluid Exchange. 52,722 miles on the odometer. I wasn't having any issues with either system . . . just wanted to have both serviced as preventative maintenance. Transmission fluid checked out fine - no signs of debris in the system, no burning smell, good color, etc. and same with the brake fluid. The brake pedal now has more "firmness" to it, and I've always suspected that there was air in the system from the factory. Transmission fluid exchange was approximately $290 and brake fluid exchange was $110.

They do not have to drop the pan with a fluid exchange. The machine used to flush/exchange the fluid reads pressures so the technician can tell if the filter is starting to build up with debris. A fluid exchange plus filter change is a lot more involved. First, the fluid has to be exchanged, then the pan dropped for filter replacement, followed by refilling fluid. If the only thing done is a pan removal and filter change, a lot of old fluid still remains in the system. That's what makes the cost go up. I will eventually do a filter change as well, but the service writer said the exchange would be fine for now. It would have been nice to replace the filter too, but it really adds a lot to the cost. As it is, I think they used 16 quarts of fluid - even though the transmission system uses just under 13. Part of that comes from flushing the old fluid out and adding the flush kit. I've always had good luck with my dealership and when I walked around the outside of the building, I could see my truck being worked on, and they definitely put the time in and did the job correctly.

Just a thought - If you measure how much fluid you pumped out and replace with that same amount of fluid, you're banking on the fact that the transmission was filled to the proper level to begin with. If it was originally under/over filled, it will continue to be under/over filled. Somewhere I remember reading on the forum that some Rangers came from the factory with the wrong fluid level.

That's exactly what I experienced. I pulled 7.5qts when I changed the filter and installed a stock depth PPE pan. I refilled with exactly 7.5qts and it drove fine for the next 1k miles. Then I installed the FitzStick and found I was almost a full qt low. Even though I didn't experience any problems, I've now got transmission peace of mind and a super easy way to verify fluid level, color & condition.

The shallow PPE pan holds about .75 of a quart more than the stock pan. Verified that with PPE a while back. That's where your low level came from.

So the PPE deep pan only holds a quart more than the PPE Shallow pan.

I use a $25 reversible transfer pump with 1/4" vinyl hose...insert tube into fill hole till it bottoms out at lowest level of sump...same with Fitzstick except you'll need longer tubes...quick, easy and clean...

I note how much was pumped out (mine was 7 quarts) and fill with same amount...

Great pic and brought memories flooding back to me.

I was trying to impress a girl and I had just watched American Graffiti. We were cruising on the beach in the old FJ40 with no top, doors off, and windshield down.

I spot a 55-gallon drum on the beach, they were used for trashcans, and pictured the scene in American Graffiti, and promptly swerved to run it over.

LOL, I got high centered on it! Had to bust out the jack! What a dork! =p

That's okay, I later further impressed her by jumping that FJ and busting both front leaf springs ...

Those glory days! =D

Yeah, @subquark , it doesn’t get any better than a girl that likes to go cruising on the beach with no top!

Same one I have...not long.

Just make sure and don't depend on the barbs to hold the hoses on. Back it up with some hose clamps and make sure your discharge is firmly fastened inside a jug or other receptacle.

Ask me how I know. There's nothing like spraying ATF all over the truck, garage, car parked next to it and inside the open truck windows and then having a truck you can't move outside to clean until you finish with the ATF change.

Yep I used something similar, a vacuum pump with a long flexible probe and a vacuum chamber. Was easily able to suck out 4 litres from the dipstick hole. Replaced 4 litres, drove it for a week, and repeated.
