Default Auto Transmission Fluid Change

I've been reading with interest all the auto transmission threads here as I know I'll be doing this in the future.

Looking at my scheduled maintenance guide it reads:
60,000 miles
Change transmission fluid and filter on all vehicles equiped with the TorqShift transmission. Consult your dealer for particular requirements.

Wow! 60,000 miles for the first fulid change?


Questions:
1. What is TorqShift?

2. Would it be better to change the fluid and filter much earlier than this?

3. Would earlier changes, say at 20,000 mile intervals eliminate the need for a complete transmission flush?

I've never changed auto transmission fluid myself so I want to be prepared and educated when the time comes.

Educate me folks!

I took mine to the dealership when it turned 65,000 miles and they did a chemical flush. Well worth it for them to do it rather laying on my back doing it myself. Don't over tighten the trans pan bolts.

they put some additives in the fluid that are supposdly supposed to help prolong the life of the tranny but i dont know if they work or or dont work and they hook a machine up to the trans usually through the dipstick or cooler lines and exchange the fluid...that gets most of the old fluid out...they usually do it with the truck running and in whatever gear the tranny has the most pressure

You'll be surprised to find that 3/4 of the time, the recommended service intervals from manufacturers can be detrimental to an automobile's life span. I suspect they do it to gain service bay business. Either way, I'm very picky about my transmission, so the fluid has been replaced at 20K, and again at 46K. When I changed the filter in my Ranger at 46K, the filter element was filthy, and only after 26,000 miles or so. I definitely recommend full fluid changes as well at 20K intervals. Unfortunately, full fluid changes necessitate removing the fluid from the torque converter, which can be a pain. This is why companies offer the pump and fill. However I just can't trust some jiffy lube or even a dealer to pump fluid through my transmission. As for TorqShift, it's most likely the "cool" little series name they give the automatic transmissions. The 80's had the SelectShift autos.

Did you do the 4~5 quart change or have the trans flushed each time?

Would you reccomend doing a 4~5 quart change to get the factory fluid out in an attempt to remove any metal particles captured by the filter during break in?

Agreed! I was planning on changing it way before the recommended 60,000 miles.

Right now I've only done the 4-5 quart flush. But I'm gonna drop the pan again here soon and do it again to make sure all the junk is out of the transmission. Apparently there is a drain plug in the torque converter, and you may be able to get some fluid out of that, but usually you'll always end up with at least a quart of the original fluid left. A full flush is about the only way to get rid of all the old fluid. I've heard that by 3 4-5 quart fluid changes, most of the original fluid is out.

Also, as a word of advice, you may find two things in your pan if your trans pan has never been opened before. One, there may be tiny little aluminum "pucks" about half the diameter or an ink pen. These pucks are used in the original trans pan gasket to prevent it from being crushed on the assembly line. Some people highly recommend the reuse of the factory gasket for this reason as long as the gasket is still in good shape. Two, you may find a little rubber "lollipop" in there as well. This is normal as well, it is what Ford put in the dipstick hole to keep stuff out of the transmission during assembly/storage. Neither of these items were in my truck when I changed the fluid, which is how I know the fluid was changed at least once before.

These next two pictures are not mine, however the third picture is mine.

Here's a picture of the pucks.




And the lollipop.




And finally, what my transmission filter looked like.

I flushed mine at 80k miles and I had no metal shavings and the fluid was clean, if you do a flush its about 125$. Basically will also let you know if your psi is correct and if you have anything wrong shavings etc. Shouldnt change it yourself, need to keep pressure up.

Fordzilla80,
Very good info and photos! Thanks!
By doing the 4~5 quart change several times depending on how long you wait before doing the next change, do you think you're eliminating the need to do a full machine flush?

It seems it would be cheaper to just do the machine flush.

I'm been thinking of doing 4~5 a quart change just to get the factory fluid and shavings if any out.



Justincredible,
Thanks! I figured a full flush would be around $150 or so.

Where is the bolt to the torque converter?

I can't seem to locate it...

Hello. I am new to the forum. I purchased a used 2006 Ford Ranger Sport 4x4 less than two weeks ago. It has the 4.0L V6 and it has an automatic transmission. It just hit 63,000 miles. I flushed the engine with Seafoam and changed the oil last weekend. This coming weekend I plan to change the automatic transmission fluid and the filter. I also plan to do the transfer case and the front and rear differentials at the same time. I don't know the the maintenance history so I am assuming that all the fluids are original except for the engine oil. I have purchased the transmission filter and all the fluids I need. I have been reading posts already about how to do a tranny flush. My questions are: If I want to flush the tranny and change the filter, which should I do first? Flush or change filter? Does anyone know which line is in and which is out on the tranny cooler? I have more questions but I am using the wi-fi at mcdonalds and they are about to boot me out of here. Any further advise would be greatly appreciated! Thank you!
