Today’s customers demand a transmission which shifts smoothly, is durable, and delivers excellent fuel economy all at the same time.
To accomplish these benefits we would install what is known as an automatic transmission shift kit, which is probably one of the most misunderstood upgrades in the automotive world.
Many people know the words, but not many fully understand what a shift kit truly does or why it’s desired. In short, an automatic transmission shift kit modifies the transmission’s shift timing in order to dramatically increase shift firmness and durability of the transmission components.
This is desirable because the automobile manufacturer’s engineers sometimes allow far too much shift overlap (when the transmission is actually in two gears at once) in an effort to increase shift smoothness. It’s this overly smooth, disconnected feeling that earned early automatic transmissions the label “slush box.”
While the extended shift overlap creates a very smooth shift, it also reduces the efficiency and durability of the transmission by making the friction surfaces work overtime. The added friction also creates excessive heat, which prematurely wears out seals and clutches.
Transmission shift kits can reduce this overlap time while improving the overall shifting action. By better utilizing the energy normally turned into heat by slipping during extended overlap, shift kits allow you to instead use that inertial energy for forward motion with quicker shifts, therefore you’re also able to notice improved city fuel economy.
Most vehicle owners are willing to live with the faster shift patterns in exchange for the extended durability and added fuel economy. Plus, the fact that shift kits can be installed in a few hours without removing the transmission from the vehicle makes them a logical upgrade.
We carry a variety of shift kits for most makes and models and would be more than happy to answer any questions you have. However, due to the fact that one misplaced shift valve or spring can result in a malfunctioning or damaged transmission, it’s highly recommended that you allow the experts at Mister Transmission to perform the installation of a shift kit for you. To have a shift kit installed in your vehicle’s transmission, please contact your local Mister Transmission.
The evolution of transmissions has made these machines and systems increasingly complex. When transmission repairs are required, determining the cause and cure for what ails can be tricky.
