JASPER Conducts Transmission Submersion Testing

The test checks assembled tranny units for leaks before they are dynamometer tested, and is a great way for Jasper to improve the quality of its transmissions for its customers.

Have you ever had one of those pesky leaks on a transmission that you just can’t seem to find?  Jasper Engines & Transmissions has created a transmission submersion test to check assembled units for leaks before they are dynamometer tested.  

“This procedure was initially developed to check JASPER transmissions for the United States Postal Service,” said Craig Leuck, JASPER Transmission Division Manager. “We developed an internal linkage system for their transmissions and needed a way to check these units for leaks.”

When the remanufactured transmission is assembled, Associates seal off all external ports and seals, then inject five pounds of air through the dipstick hole of the transmission.  The unit is then submerged in a large tank of water and the Associate checks for air bubbles escaping from the transmission. Units will not be dynamometer tested until they pass this crucial test.

“We’ve found this to be a great way of improving the quality of our transmissions to the customer,” says Leuck. “If five pounds of air can detect an external leak, we can eliminate the chance of transmission fluid finding the same leak.”

JASPER currently submerge tests rear-wheel-drive Ford & Chrysler transmissions, along with front wheel-drive GM, the 4L80E and 700R4 postal transmissions. Added Leuck, “The goal is to have the ability to dunk test all light-duty transmissions.”
