Keep fluid overflow off of your car and the track with Canton Racing automatic transmission expansion tanks! These tanks are designed to catch pressurized fluid when the car is running hot and then drain it back to the transmission as it cools. Constructed from .100 in. aluminum, these tanks have a 1.5 pint capacity that meets NHRA and IHRA overflow requirements. Canton Racing automatic transmission expansion tanks feature a petcock for draining excess fluid, a sintered bronze vent, and mounting flanges for easy panel mounting.
