When it comes to all-wheel drive transmissions, Jasper Engines & Transmissions makes it a point to include the gearbox with each remanufactured unit.

In the GM 4T65E, for example, JASPER has found components inside the gearbox that will fail over time and cause damage to the internal gears.

“There’s a washer hidden underneath the final drive sun gear of the 4T65E AWD gearbox (see Figure 1) that is a high-wear item,” says Craig Leuck, JASPER Transmission Division Manager. “There are five tabs on this washer that will either wear down or break off (see Figure 2). That metal will damage, or destroy, the gears inside the case (see Figure 3).”

JASPER takes the stand that even though the vehicle’s current gearbox may not appear to be worn out, it’s only a matter of time before metal pieces appear inside the case. “Do you want to take the chance on a gearbox having a worn washer that may not have completely failed yet,” asks Leuck. “Or, would you like a complete unit that’s a quality product to the customer?”
