Transmission Fluid Change In 24 Years! How Bad Does it Look? F-150

Some folks say not to change the automatic transmission fluid on an older high mileage vehicle like this 1997 Ford F150 with 138K original miles. Changing the fluid and flushing the fluid are two different things. Flushing can push particles of contamination into small orifices and clog them which can cause transmission failure. Draining the old fluid and replacing it with a new filter is more gradual and tends to leave the bad stuff undisturbed. Fresh fluid has properties that improve lubrication and also help to maintain the proper fluid pressure necessary for smooth shifting. This video shows what the first transmission fluid change in 24 years on an Ford F150 transmission. Feel free to leave a comment or question down belowand if you get a chance smash the like button. I appreciate you taking the time to watch the video, thanks! -Glen

[@russ_vee_jr4199]

Good video. Simple and Straitforword. FWIW: I cut the heads off of 4 pan bolts that are a little longer than the originals and round off the cut ends. I then cut slots into the rounded ends for a screw driver and thread them into the 4 corners of the case. This keeps the gasket aligned as I put the pan back up. The modified bolts sleep in my 'Odds and Ends' plastic case until needed again. I also disconnect the cooling lines at the radiator and drain the torque coverter. If replacing all that fluid causes slippage, it simply means I was headed for an overhaul soon anyway. Again, Good Video......

You might do a flush. As good as that pan looked, I wouldn't be afraid to do a full fluid exchange on it. I've never had trouble before. Whenever I buy a used vehicle, the first thing I do, is change ALL the fluids. That includes the power steering, flushing the brake lines, as well as the engine oil, transmission fluid, differential (s) oil and even the transfer case.(if FWD) I also flush the coolant, especially, if it looks brown.

Good maintenance is the way to go!

[@jubblybits6155]

If it hasn’t been changed in more than 100k miles it’s better to leave some of the old fluid in. That grit in the old fluid can help. If it’s been that long and there is no grit left in the fluid it can cause slipping.

Now they don't even give you a dipstick. You have to get under the car and remove a fill plug, with the trans warm, and see if the fluid dribbles out.

I just check my oil on my truck and its really darker than this one do you think it will help if a do a full flush again. Last time i just drop the pan change filter an gasket an add new oil

A second fluid change with the correct fluid should make a big difference.

[@ripptydevibes2581]

That was a risky call on 24 yr fluid!! In my 15yr owning my shop working on all makes, I have seen several instances where older cars OR higher mileage dirty fluid changes lead to nearly instant transmisison failure. If I get a 25yr car with low miles needing its first fluid change I wont even risk it. If I get a high mileage car with no history and dirty fluid I wont do it unless they insist after my warnings lol.

Why not pump it out through the dip-stick since you are not changing the filter?

[@ozzstars_cars]

To slow of a process and wouldn't be able to access and replace the 24 year old filter.

[@chriss4365]

How can the oil still lubricate the gears? You should of used the cooler lines to pump it out so the pan will be empty when you remove it. You can try at 205 reseal for that leaking seal. You only got out like 40% of the old stuff opening the pan if you use the cooler line you can remove fluid and add new fluid until its clear red otherwise their is still old crap in their. Don't drop the pan every 1k just use the cooler line.
