You will see the switches, unscrew them and pull them out , u might lose a little fluid when u do the one thats lower so be ready to pop the other one on right when u take the old one off.
I think someone posted better instructions with pics if u search!

well you posted the service manual instructions at the beginning of the thread so thats good enough.

Thanks for the heads up on the fluid. I didnt know if there would be any coming out and the manual didnt say anything.

Is changing the external ATF filter a good idea? I've called several shops and they say no. I haven't seen any posts showing the dirty guts of an old filter, sounds like we're replacing it because we can? Logic does tell me that a filter should be changed every now and then... my trans is going strong at 170k miles (Except bearing noise and click when shifting into reverse). Since I'm trying to stretch my tranny's life out - I suppose I'll do it. Does anyone REALLY know if it's matters though?

Why would it ever be bad to change a filter? All filters have a finite lifespan. Changing it can't hurt anything and will only help to trap additional particulate.

I found this information on this page, in short it says that the ATF filter is not a typical free-flow filter, but rather a magnetized backwash filter. So someone like me with 170k miles should probably change it. Maybe i'll cut it open once changed-out.

Below excerpt is from: http://www.lincolnvscadillac.com/tec...glifeautotrans


WHAT ABOUT THE TRANSMISSION FILTER?

Logic would seem to dictate that if there is a removable filter in the transmission that it should be replaced periodically. In actuality, this is not always the case. When most people think of a transmission filter, they apply the same logic as they do towards an oil filter. The difference between the operational characteristics of a transmission filter and an oil filter are so different that they cannot be compared. An oil filter is considered to be a ‘full-flow’ filter, meaning that the entire amount of your engine’s motor oil passes through the filter on each pass through the oil pump. The oil filter will trap any particle of about 10-15 microns or larger, which is roughly the thickness of a human hair. Eventually, the filter will become so filled with particulate matter that it can become too restrictive, causing it to go into ‘by-pass’ mode, which simply allows unfiltered oil to circulate through your engine. Obviously then, frequent oil and filter changes are necessary.

In contrast to that, a typical transmission filter is NOT a full flow filter. Only a small portion of the transmission fluid passes through the filter as it makes its way through the transmission. In fact, most of the fluid flows around the filter and up into the valve body. The idea is that eventually, most of the fluid will find its way into the filter, and any particulate matter that may be ‘swimming’ around in there will be held in the filter. When the engine is turned off, all of the transmission fluid that is being held up inside the valve body and filter will drain back into the transmission pan. This all has somewhat of a ‘backwashing’ effect on the filter, as a lot of the debris in the filter will be forced down into the pan. Many manufacturers put a magnet in the bottom of the transmission pan to collect and hold these metallic-filings and debris, to keep them from traveling through the transmission. This design is what allows manufacturers to make claims of anywhere from 50,000 miles for a filter change recommendation, all the way up to 100,000 miles.

The best recommendation for a classic muscle-car owner is to flush the transmission as often as described above, and to change the transmission filter about every 30,000 miles.

The big difference Here is A). There are 2 filters on this trans. 1, an internal non serviceable and 2, the one above an External serviceable filter. and B). these trans have a design flaw. The more you can keep the filter and solenoids clean the less wear they will have.

I have a hard shift from 2 nd to third but I think this is the problem. I took it to Aamco, but they're not trustworthy mechanics the told me I had no problems with trans just mounts. My car jerks only when it gets to about 29-31 mph. It feels like my transmission. If I knew I would have d fixed so I'm looking for advice from more exp. cl ers

I've been having a firm 2-3 shift for a while (50k?) and it's still going. Just baby the trans and change the fluids often. I do every 8-10k or oil change.

First off changing ATF filter.. Part #9 in this diagram..






Some of you guys with a older transmission have this oil jet I have a newer (suposidly fixed tranny so DO NOT have the oil jet just a NUT there (this is where u fill the transmission fluid. If u have a oil jet there I belive u have a older transmission (this was acura's band-aid to the problem)





Make sure that while removing the steel fluid line not to damage the o-ring. I replaced mine when I replaced my filter. Be sure to coat it with trans fluid before installing the line.

Just wanted to say thanks so much for this info. My TL would occasionally 'miss' the gear when downshifting to accelerate, instead of downshifting it would feel like the car switched into neutral and it would redline. If I let off the gas it would then find the gear and continue as normal.

I didn't know this filter existed before reading this, and the Acura dealer insisted when I bought it that the filter NEVER needs to be changed and I was waisting my time.

Anyways, did a drain and fill with the new ATF-DW1 fluid, used car for two oil changes, put the filter in and did another drain and fill. After putting the filter in its like a new transmission! SO crisp, smooth and confident in it's shifting. I didn't realize before how sluggish the shifting really was. And I haven't had it miss once since the filter change!!

Thanks a lot for this info. Glad you posted the photo & I was able to find an equivalent replacement in Rockauto.com for less than 1/2 price what the Acura dealer charges.
