Location: bishop, ca | The O.P. is either asking a rhetorical question, or a practical one.
As per the former, the answer is to drop the trannie pan, and when you are doing it, check for possible debris or
contamination in the pan, and on the pick-up tube's screen, and on the valve body.
As per the latter, there would be some compelling reason for worrying about the condition of the trannie fluid and/or the
operation of the transmission----in which case you would drop the trannie pan and check for possible debris or contam-
ination in the pan, and on the pick-up tube's screen, and on the valve body.
The trannie fluid's fill level and quality is checked via the dipstick and your eyes and nose and fingers.
If the trannie is not shifting well and/or if its fluid quality smells burned and discolored, you'd want to drop the pan and
find out whats-what (above).
If the trannie fluid is merely low, you can add .5 pints (only) and re-check the level after each 'dollop' of fluid is added.
Back in the daily-use-day, trannie fluid was changed about every 10K+ miles.
Now, with our pampered pets incurring careful, non-regular useage, and with much better transmission formulations,
and, after a transmission might be overhauled, changing the trannie fluid, again, might be a once-in-our-lifetimes' event.
There are about three types of trannie gaskets: silicone-tube, rubber, and cork.
The silicone type is easy to apply, but makes for a labor intensive clean-up/prep operation if the pan is dropped again.
Rubber doesn't seal/seat as well as cork (the pro's choice).
There's a very good engineering-reason why there is no drain plug in our car's trannie pans....if you have to or want to
change the fluid, you have to inspect the conditions existing inside the pan.
