Triple Tested Quality

Regardless of what category or price
level it may fall into, every
Once all the prep work
on the component parts has been completed, the impeller is welded to the front
cover. Immediately following this process, a pair of dial indicators are
employed on a rotating table to verify that the impeller body and pump drive
hub remain true.
Each unit is then
pressurized and subjected to a leak test to confirm the integrity of all the
weld seams. Lastly, each unit is computer balanced to reduce annoying and
potentially damaging drivetrain vibrations that would
occur from an unbalanced torque converter. That's Triple Tested so you can be
confident you're getting a torque converter that's ready to roll.
