WORK SAFELY! For maximum safety, perform this installation on a clean, level surface and with the engine turned off. Place blocks or wedges in front of and behind both rear wheels to prevent movement in either direction. CAUTION: To avoid any possibility of bodily injury or damage to vehicle, do not attempt installation until you are confident that the vehicle is safely secured and will not move.

WARNING: Incorrect checkball placement can result in serious transmission damage. Be sure to follow the instructions carefully. We recommend that you read through the instructions completely before beginning the installation and familiarize yourself with the installation procedure and tools required. Check the tool list at the end of these instructions for the tools required to install your B&M Chrysler TorqueFlite Shift Improver Kit.

NOTE: The B&M Chrysler TorqueFlite Shift Improver Kit is not a cure-all for an ailing transmission. If your transmission is slipping or in poor general shape, the installation of this Shift Improver Kit may worsen the condition. However, on a properly operating transmission in average condition, the Shift Improver Kit will provide the kind of transmission performance you're looking for. When installing your Shift Improver Kit there are several other B&M products you may wish to consider: Transmission Oil Cooler - We feel that it is very important that every vehicle used in a heavy duty application (racing, towing, RV, etc.) should have an oil cooler. Heat is the major cause of transmission failures, and an oil cooler is an inexpensive safeguard against overheating and failure. B&M offers a wide range of transmission coolers to suit every need, which are available at your B&M dealer. Trick Shift Performance ATF – Trick Shift performance automatic transmission fluid is the industry’s leading performance ATF. A specially blended oil with foam inhibitors, extreme pressure agents and shift improvers, this fluid assures protection while delivering the fastest possible shifts. You literally “Pour in performance.” TORQUEFLITE INTRODUCTION NOTE: Transmission components and valves are precision fit parts. Burrs and dirt are the number one enemies of an automatic transmission. Cleanliness is very important, so a clean work area or bench is necessary. We suggest a clean work bench top from which oil can easily be cleaned or a large piece of cardboard. This kit contains all parts necessary to obtain two levels of performance depending on intended use: Heavy Duty: Towing, campers, motor homes, police, taxi, on and off-road desert vehicles and 4-wheelers. Street/Strip: Dual purpose performance vehicles. Street and strip high performance cars.  Technical Support (707) 544‐4761                    1                                www.HURST‐SHIFTERS.com
