Racing transmissions produce internal pressures that force your stock dipstick out of the tube and allow ATF (automatic transmission fluid) to escape. Leaking fluid will make a mess, but losing fluid can destroy a transmission in a hurry. JEGS locking dipstick with the tube will solve your problem, keep your transmission fluid where it needs to be, and prevent catastrophic transmission failure. The locking lever is easy to use and allows you to check your ATF fluid quickly and easily.JEGS Locking Dipstick Dimensions
