If your levels are low, but the fluid looks clean, you might just top off the system.If your engine has not been run in about an hour and you do not live in an extremely hot climate refer to the Cold Reading for proper levels. X Research source Dipsticks list a hot and cold reading. It should be labeled clearly and easy to access on most cars, close to the oil dipstick. Look for the transmission fluid dipstick, which is usually red-handled.On most vehicles, you can check the level with a dipstick, while the engine is running.

It's typically colored red or green to distinguish it from motor oil and other fluids in the vehicle. Automatic transmission fluid (ATF) is the fluid used in vehicles with self-shifting or automatic transmissions. X Expert Source Ed BeeryĪutomotive Specialist Expert Interview. Will changing the filter/strainer make a difference to 99.9% of owners: NO, except for piece of mind, and for some, that is good enough.Check the level of transmission fluid first using the dipstick. Is it BEST to swap out the strainer/filter: Yes Is it good to swap out the transmission fluid: YES If there were enough 'fuzz' as you call it to the point it would completely impede/block the strainer/filter, the transmission would not work to begin with. There is 'best' and 'does it make a difference.' The two often get mixed up on automotive forums. Not the best thing to do, but happens all of the time. Numerous transmissions go 500k miles without even a fluid change. So, I agree, but to me, this is an area where people sit around typing away on a keyboard splitting hairs which make little to no difference in the long run for 99% of owners out there. I have rebuilt multiple transmission and not little 400hp engine types. There are also no valve bodies or any other small orifices that can become clogged with excess "sludge".Ĭlick to expand.I am not sure why your posting that, to educate me? Or just for others? I should share, I would agree with your 'mechanic' to a degree. I wouldn't expect a filter for diffs or the t-case, as they don't have friction material that is going to be floating around, and even if they did (for limited slip differentials for example), fluid change intervals should be high enough that the excess friction material is removed. engine oil vs transmission oil), the transmission most definitely will become contaminated over the course of time with friction material from the 4 clutch packs. While I agree that they aren't the same (i.e. Not to mention the fact that there are magnets in the pan anyway to catch ferrous shavings/debris from the clutch plates/wear in. With frequent enough fluid changes, you should be good to go to not have to replace the strainer/filter on every fluid change, and looking at pictures of the strainer/filter show that is is not likely to be filtering out the friction material anyway, at least effectively. There are also no valve bodies or any other small orifices that can become clogged with excess "sludge".ĮDIT: I don't really think that changing the strainer/filter in the pan is that necessary at very low intervals - my biggest worry would be actually chunks of something getting sucked into the pump and being pushed through the valve body/solenoids/etc. Click to expand.While I agree that they aren't the same (i.e.
