transmission fluid change questions!

OK now this is how you replace 3rd and 4th clutch transmission fluid pressure switch.
If your trans is jerking I "heard" that replacing these will help the tranny shift smoother and maybee save your tranny... Some in the 2nd and 3rd gen TL replaced these switches and noticed alot of improvement in shifting quality.
Parts #12 and #13..
I hope this save some of you guys from what happen to me and spending $2500-$3500 on a new transmission... If you have ANY questions please just ask or PM me I had this car for over 9 years (got it in april 2000 pre ordered b4 it was released) and was on 260hp.com which morphed into this site and learned almost everything from you guys so might as well share what I learned with the new people getting this car and saving them some money!! I am a do-it yourself kinda "broke" guy that will try to fix everything myself and because of this site I saved ALOT of money!!

I know you guys are talking 2G but for an 08 3G I keep getting mixed info about the ATF. Some forums said every 30k but the dealer says a service light will come on before 100k & i just think thats too long to wait. I do allot of stop & go driving in Chicago traffic & as a realtor. Any pointers?

you just basically take the splash guard off the driver side (not the fender liner but the one that goes across the bottom of the bumper) and the switches are staring at you behind the driver's side wheel. The lower one, closer to the wheel is the 3rd gear switch while the higher one is 4th gear switch. I havent driven the car since I changed it so I cant report on the difference yet. When you take the switches out, there is some tranny fluid that comes out but not a lot, maybe a few ounces. The cost is about 50 bucks a switch.

I think changing transmission filter won't do anything to help your transmission. When it gets clogged its usually after the fact of when clutch pack start to come apart and the metal shavings can clog up the filter. I agree that clogged filter can accelerate the failure due to the restricted flow of fluid, BUT, it will not save your transmission... It might give you 2-3 month of extra life, but its on its way out. I would not waste any money on any of the woo do crap of installing coolers, changing filters, or changing fluid every 7K miles. Just follow simple steps:
1) change fluid every 3 year/30 miles
2) Be easy on tranmsission
3) avoid excessive shifting 2-3 and 3-2.
If it does not help, then it does not help, and there is nothing you can do about it.

as for the pressure switches... they get gummed up over time and that's how they begin to fail.... if u remove them and clean them out with sensor safe break cleaner... that will fix it 90% of the time.
that's what my guy did when i got my trans rebuilt and everything is fine. he said he never replaced the pressure switches, cause they basicaly never FAIL... they just become less sensitive due to HORRIBLE fluid gum building up inside on the switch... clean it and the switch is basically new.
nice to hear it made a noticeable difference on ur ride zac

wow I think I'm definitely gonna try a DIY on the trans fluid drain & refill...the dealer just quoted me $105! One guys says do it every 15-20k and another dude last week said a service light comes on at about 100k. I'm at 39k so I think its time, allot of the first few miles I put on the car were highway but I've been doing allot of stop & go in wonderful Chicago traffic lately.

15-20k for a 3G TL tranny is a bit too much, heck I do my tranny every 30k. you should at least exceed that, they pretty much solved the tranny problems for your year.
okay guys, update on the pressure switch swap. shifts are slightly smoother but the hard shift hasnt gone away completely. so while it works, you be the judge if its worth the 50 dollars for parts. labor is as easy as changing the oil though.

Recently and suddenly started having tranny problems. Slipped and banged into gear while on a highway exit ramp and then again later that eve going up a hill at 75. 3rd gear seems to be the issue. No CEL at the time. Friday night tranny slipped, got a CEL along with other lights and went into limp mode. Got the CEL read and it's a P0780. Seems to point to a electrical/solenoid issue. Anyone run across this? What are my chances that the solenoid clean/replace will fix this?
BTW, the car has 129K on it and has had the recal performed (before I got the car with 29K on it).

FYI
i have an MDX in the family and it was slipping in gear on the highway.
I did a 3x3 on the car and problems literally went away. So if you have not attempted the trans fluid change and ATF filter i'd recommend you try it. it's worth a try i'd say if your fluid isn't pristeen at the moment

No love from Acura. They refuse to offer anything. At least my local dealer stepped up somewhat. As much as I like the cars, this is the last Acura/Honda product I will own. How they can engineer a car that costs nearly $40k when new and have transmission failures such as these in incomprehensible to me. I can buy a $15k Kia with a transmission that lasts longer.

this sucks
So it was time for a tranny fluid change [35k since last] and I drained what was some very black fluid. No metal on the magnetic drain plug - good. But after filling up new problems.
The only symptom initially is excessive flare on 2-3 upshift. This gets me thinking that the 3rd gear pressure switch needs to be replaced or have the tube cleaned out.
No time to work on it for a few days.
Now it is hit or miss whether or not it will even shift into 3rd from 2nd or 4th. Sometimes the 3rd gear clutch never engages, but sometimes it does with only the excessive flare. I bought a new pressure switch today and some Z1 atf [previously used mobile1 full-syn]. Hopefully get time to change it out Friday as I have to remove the battery.
I tend to think that [from the trouble shooting in the manual] that if it were any other part failing there would be symptoms with other gears.

So today there were problems with other gears...
On the way to work, all of a sudden there was no gear engagement regardless of shifter position. It is now in a shop waiting for diagnostics to come back. I should get a call later today with bad news/bad news.

Nope, Texas. Talked with the shop on Friday, and they said the fluid was way burned [<150 miles on the new fluid], and the PCM tossed out every code in the book. Should get some quotes back today on replacement options.

YEP... i got the jet kit on mine..
and so does my family 02 MDX.
just remove that and then replace the exact amount of fluid you removed.
I emptied min in a jug... then put a line of tape exactly where the fluid level was so i was 100% sure to put in the exact same amount.
