Just noticed fluid was kinda brown. I know manual says 120k or 6 years...mine is at 80k might as well do it.

just wondering if its 3 or 4 quarts..? and quick drain and fill...?

 

its 3 quarts ATF-Z1 for a drain/fill (honda does not recommend any "flush" systems), you'll notice an immediate improvement in shifting if its never been changed at 80k.

 

Agree with the first part, and definitely go for it, but.... I haven't noticed any difference in the performance of the transmission (which may lend credence to the longish change interval).

 

dont forget to change your filter too.. that will help..

 

i was told the Transmission fluid filter is internal to the tranny and can't be removed. thus you can't do a proper "flush" with these transmissions.

is this incorrect?

 

I had my auto-trans fluid changed last year on my 06 TSX at the dealer in Sacramento - it was brown - and they do a drain/refill/drive/drain/refill/road test. This was at about 4 yrs and 40,000 miles, first time. It did run smoother ... at least I want to think so for the $200 cost.

My Mercedes-Benz crazed friend (machinist by trade) also told me changing the fluids in addition to standard crankcase oil (i.e., brake, coolant and auto-trans) is recommended every few years for his MB. Reasons various - brake fluid attracts moisture; coolant degrades; auto-trans oil gets hot and will degrade. He's a perfectionist, so I don't even try to argue the credibility of his claims.

Needless to say, I have done all those items in the past year knowing the shops are healthy with my $$ and I hope it makes my TSX last a little longer. Support that economy! I wonder if the power steering fluid should be changed out?

That's my $200 worth.

 

There is a filter outside. It sits on top of the transmission (if you look in, down, and below the fuse/relay boxes behind the battery, you can see it in-line in one of the transmission fluid lines). There isn't a change interval for this filter (lifetime?), so I assume it doesn't do much, but.... it's not too tough to change and fairly cheap (+- $20), so I changed it anyway.

 

It's part #4 in the diagram. Check the manual on how much needs to be added as it varies from each Honda model but it is usually less than 3 quarts for AT and 2 for MT. Also get a replacement washer for the drain nut.

 

mine took in almost 3 quarts
i did not put it on a lift, instead i used jack stands in the front which may affected how much came out.

 

ill say that its true changing the fluid helps. i have a92 accord , and i just drained the hole thing and refilled (my trany line to radiatory got cut soo...)
