How to know whether tranny is slipping?

• Abnormal gear slippage during upshifts or downshifts. (Commonly between 2-3 and 3-4 shifts)
• Erratic or excessively harsh shifting.

what does above mean? Or I need to wait until tranny fail?

Thanks

It means exactly what you posted. The trans will slip between shifts, usually on the up shift. Harsh shifting means that. It will shift hard into gear, meaning its not smooth.

Every one of my 5 failures did this before they died. I would notice it and within 1k miles or less it would usually fail.

I was able to video tape one of the failures. Look at how the rpm spikes up a few hundred as it shifts. That is a slipping trans.

Lol - my tranny slipped like that for almost 30k miles before it crapped out.

Now i got 20k miles on a post 2009 rebuilt with DW-1 fuild and it shifts faster and much better than the tranny did when it was brand new with old z1 fluid.

I replace the transmission oil every 2 years (still with original transmission). I will switch to DW-1 next time.
Thanks

Switch to 1 Year Intervals and ADD a Mangnefine Inline Filter... You should try to keep the ATF as Cooler and Cleaner as you can! Heat = Wear on ATF = Easiest for the Clutches to Crap themselfs Faster....

What year is your TL ? and how many miles ?
Try a 3x3 with the new Honda fluid. Consider replacing the fluid filter and cleaning the solenoid screens. Worth a shot !

3 drain and fill's x 3 quarts each time... you're gonna need like 12-13 quarts total, but dont do the drain and fills all at once... spread it out at least over a week or two (works for me). also, use the ATF-DW1!!! use anything else and your bank account will be hurting for a while!!

i had the same problem at about 88k miles .. i literally broke down in front of the stealership .. LUCKILY i was eligible for the recall on the tranny .. i got it replaced for free .. i had pay for the mounts which was about $400 ..

i think i have a bad motor mount or something though .. at the end of shifting from 1st to second the whole front end kinda slowly jerks .. it did it even right after they put the trann in .. (i hope it's only a mount)

you got a warranty unit- not recall

how long since you changed the ATF?
Have you looked at the mounts- front and rear are vac boosted
front often goes around 70kmiles,,every 70k,,,,

It only took two months for the first detection of tranny hiccup to the complete loss of 3rd gear on my '02 TL-S.

not sure if you were talkin to me .. but, the OE tranny death happened to me about 88k .. i am the 2nd owner of the car .. all the symptoms happened right at the stealership infront of the clerk .. as far as me changing fluid, i never did ..

Have you checked or replaced your motor mounts lately? Have your axles inspected as well. They would cause that

Trust me, when your transmission goes out you'll know.....

Look for "staggering" away from lights, like it's in a too high a gear. This means the trans is in limp mode. Also, slipping will happen when you go around a long gentle curve, like a highway off ramp. As you're turning you'll hear the RPM's go up when your foot hasn't moved. This means the friction surfaces are gone and once they're gone, they don't come back.

As I said, if you have a toasted trans you'll know it. Sadly, if you're asking the question, you probably have experienced some or all of the symptoms....
