Jasper Engines & Transmissions has recognized a high-wear item on the rear-wheel drive Chrysler overdrive transmission cases. And ironically enough, it’s the hole for the dipstick tube.
“When cores come in for remanufacturing, JASPER has found RWD Chrysler overdrive transmission cases with an enlarged hole for the dipstick tube,” says Craig Leuck, JASPER Transmission Division Manager. “The hole becomes enlarged over time because the dipstick tube will move around inside the case.”
JASPER will use a special reaming tool to oversize the diameter of the dipstick tube hole. A brass bushing is then driven into the case and held in place with sealant (see Figure 1). “This update is made before the assembled transmission undergoes submersion testing in water, and checked for leaks,” added Leuck.
