Had a bad 4th gear pressure switch, replaced under warranty, dealer recommends flushing tranny as they claim it is recommended by Acura. Sounds a bit overkill to me, what do you think??

Thanks

 

NO FLUSH!!!!!...drain and fill yes...

 

the acura owners book misleadingly calls a 3x3 manual fluid change- a ~flush~
and if you read closely, we have not been doing it right!
after 3 full drain and refills.. a 4th fill takes place
We have been doing it as the 3rd fill is the final one

Acura says to do that ~flush~ if you ever had to add dex3 in an emergency as they are not ok to mix
With the known clutch wear problems and you having a bad pressure switch, its a fair thing to change out the trans fluid- it must be dirty to kill a pressure switch

On the newer cars they are saying every 30k miles
Some guys are doing a basic 3qt drain and refill while others trust the 3x3 to keep the trans in better shape either every 15 or 30k miles

If you are still under the extended trans warranty and the dealer says to ~flush~ the trans, by all means do it right away- the trans will probably fail in less than a month and you get a freebie replacement- thats like getting half a new car!

 

What do you mean by this? My warranty is up May 19th. I am assuming the flush is not really needed. Is flushing just a precaution so they can't say I didn't maintain properly if it fails in the next 3 months?

 

Flushes are not recommended by acura.

 

in this case Kris- Acura replaced the pressure switch and must have found really dirty fluid so they said to do their ~flush~ (manual drain and fill)

I would do it at home, keep the receipt and wait for failure to occur

 

they may have been giving you the silent signal---
your trans has a problem we cant warranty, BUT, finish it off and get back here!

 

No its not a precaution or way to deny you coverage- you need to keep fresh fluid in all the parts of the car- radiator- power steering, brakes, engine oil, trans fluid

Cmon man you have been a member here since 2005 and you havent read any pages off the tranny failiure thread?

These things are like bic lighters. goes into gear 5000 times... then one day- click click click and nothing

 

Yes of course I have read all the messages about tranny failure. I am just wondering because I've seen some reference to failure after changing the oil, and so if it's going to happen, I guess whatever I can do to help it along would be good as I get close to the end of the warranty.. If I get to May 19th and it's still good, I will be nervous every day after that!

 

then get under the car and have at it~ its too simple!
Keep the receipts for the HONDA ZR1 atf

a good rinsing out of old fluid and loosened clutch material, combined with new slippery fluid should have you in a loaner within a month
