is it neccessary to drop the transmissions oil pan and clean it of metal shavings when changing the ATF on a auto trans?

 

I don't think I've heard of anyone doing anything other than drain it, refill, drive awhile, drain it, refill it

 

me neither. but i changed a friends ATF in his 6th gen V6 and he started experiancing rough shifting a little bit afterwards. and i dont know if its either from me or just coincidence. and he said he did some reading online and he read that you need to replace the trans filter and clean the pan. but i read that the accords trans filter is unservicable and i havent heard anyone say anything about cleaning the pan. my haynes manual doesnt say anything about it either. just seeing if anyone can confirm that

 

Honda autos dont have transmission drain pans. Remove the plug, clean the magnet on the drain plug, reinstall with new washer. Refill the fluid from fill hole on top of trans.

BTW I hope you plan to only use Honda fluid because anything else will cause harsh shifting.

 

Its been my experience that if you haven't changed your fluid for let say 40K miles, don't change it. Once you do, all the sludge, and residue that is helping your car shift smooth, and help the gears mesh with a tighter tolerance will be moved away, then you most likely will see slippage and destruction. Always use Honda ATF when you change though. Any lastly, never, never have the trans "Flushed", always drain then fill.

Sure this is a great idea on your chevy, but if ya find a 'pan' on a Honda please send pics.
As far as the BS about not changing the fluid because sludge helps your trans shift smooth; that person has never been inside of a Honda trans, or they wouldn't make such a statement.
Keep clean fluid, no matter what!!! I stand by the Honda Z-1 ATF. Great Stuff

The "supposed" BS about changing the ATF fluid that I have stated has unfortunatly been experienced by me in the past by depending on pure book knowledge, instead of what occurs in the real world. In the real world, I have changed the ATF Fluid(Honda ATF) in Honda Accords (4 to be exact) with over 85K mi, and have first hand seen them take a $hit. Not all cars have had the ATF fluid changed according to factory specs, so it can't be assumed. Keeping clean fluid is correct, but as far as the ATs go in Hondas, if isn't hasn't been changed for that long, I have experienced "Don't change it". Two Accords I have owned have had 100K+ miles on the stock transmission and contained fluid that was never changed by me, I have owned both cars since around 75K mi. No transmission issues what-so-ever.

 

if you are referring to your car, there is no pan as there are no user serviceable parts inside the trans. the filter is a screen that gets changed when the unit is opened up for major service.

drain and fill or trans flush machine (the type that uses your car's trans pump)......
