Frequently Asked Questions:
- What is a transmission filler tube “top hat”? The “top hat” is a small seal or grommet that sits at the very top of your transmission fluid filler tube. Its primary purpose is to seal around the transmission dipstick, preventing foreign contaminants from entering the transmission.
- Why is this component important? This small seal prevents dust, dirt, water, and other debris from entering your transmission fluid. Contaminated fluid can lead to premature wear, reduced performance, and costly transmission damage.
- How do I know if I need a new top hat? If your original top hat is missing, cracked, hardened, or no longer provides a snug fit around the dipstick, it needs replacement. You might also notice dirt or grime accumulating around the top of the filler tube.
