Moroso Automatic Transmission Expansion Tanks

4.67 out of 5 stars 3 Customer Reviews

These Moroso automatic transmission expansion tanks prevent fluid mist from spraying on the race surface, back of your car and tires. Pressurized fluid is captured in the expansion tank and will drain back into the transmission as the transmission cools. Excess fluid may also be drained between rounds, by using the ball valve. A mounting bracket is included. These tanks meet IHRA Top Sportsman and Top Dragster requirements for 1 pint transmission overflow rule.
