ABSTRACT:
An automatic transmission fluid dipstick-shielding tube and method of use for shielding the terminal end of the dipstick whereon fluid level indicia are imprinted to ensure accurate measurement of the fluid level within an automatic transmission or other similar machinery is disclosed. The present dipstick-shielding tube provides a physical barrier which blocks fluid from splashing over the terminal end of the dipstick to facilitate an accurate fluid level reading. In a method of the present invention, the original equipment dipstick tube is initially removed from the transmission housing. Next, the present dipstick-shielding tube is installed in the transmission housing and the original equipment dipstick tube is reinserted into the housing in end-to-end relation with the present dipstick-shielding tube. Thereafter, the original equipment dipstick is replaced providing an accurate fluid level reading.
