I addition to my pair of Lexus' I own, I also own a 2002 Ford Explorer 2WD and guess what? - NO TRANNY DIPSTICK !!!
However, I can get underneath the vehicle and check the fluid level. There is a plug that is removable located about two inches
below the top of the fluid pan. I unscrew the plug, insert finger, if I "feel" fluid, it is full. Go figure!!!!!!
