JH Mountain Auto Services in Silverthorne now provides the GM 6T40 and 45E FWD and AWD Transmission Replacement Options from JASPER Engines & Transmissions.  These transmissions are available for the following 2008-2011 applications:  Chevrolet Equinox and Malibu  |  GMC Terrain  |  Pontiac G6  |  Saturn Aura  |  Buick Regal and LaCrosse

Each JASPER remanufactured GM 6T40/45E is a 100% dynamometer tested through a state-of-the-art CAN software package allowing the TEHCM to shift itself eliminating the chance of shifting concerns and ensures a quality product for the customer.  The 6T40/45E TEHCM (transmission electronic hydraulic control module) is 100% hydraulically and electronically tested, reducing the chance of a TEHCM and/or CAN software malfunction.  Great care is taken to ensure each 6T40/45E can stand up to the rigors of everyday life.  An updated 3/5/reverse piston is 100% installed, eliminating the concern of losing those gears during driving.

All wear areas of the valve body are vacuum tested and reamed to oversize to restore the hydraulic integrity of the circuit.  This reduces the chance of low fluid pressures causing slipped clutches. The JASPER remanufactured GM 6T40/45E is covered by a three-year, 100,000 mile, nationwide parts, and labor warranty. 

Talk to our team at JH Mountain Auto Services in Silverthorne about your specific needs and any transmission replacement questions you might have for your Chevrolet, GMC, Pontiac, Saturn, or Buick.  We'd be happy to answer them for you and see if a JASPER remanufactured transmission replacement is right for you. We take your automotive safety seriously!
