Keisler Engineering's Automatic Transmission Upgrade for Your Classic Corvette

For more than a decade, General Motors has used automatic transmissions controlled by an electronic brain. This ended their use of vacuum actuated models. Although many classic car restoration purists would balk at the idea of putting such an item in their old-school muscle car, this innovation has increased the strength, torque, shifting quality and overall performance of their automatic transmission vehicles.

For those intrepid classic Corvette owners, Keisler Engineering has something for you! The A41 is a new generation of GM transmissions. Based on the research and expertise you would expect from Keisler, these electronically controlled automatic transmissions for classic Corvettes are the highest quality available.

The A41 electronically controlled automatic overdrive transmission features a 4^th gear ratio of .70 allowing a low rpm cruising speed and quality of shifting found only in newer high performance cars. The torque capacity of the A41 ranges from 450 ft-lbs to 650 ft-lbs depending on which of the three models you choose.

Corvette owners wanting to upgrade a transmission in the past would have to spend a fair amount of time finding a mish-mash of appropriate parts from different manufacturers. For the first time ever, Keisler Engineering offers a complete kit for the classic muscle car restoration enthusiast with all the application specific items including crossmember, dipstick, driveshaft, cooler lines, TPS, wiring, shifter linkage, Speedo cable and installation manual. Each A41 electronically controlled automatic transmission includes a stall torque converter that is custom made and dyno tested with transmission and electronically pre-programmed Keisler Transmission Controller.

As with most of Keisler Engineering’s products, the A41 is a high performance, technically superior automatic transmission. The brainy gear-heads at Keisler have managed to make the installation of this transmission as easy as any of their other PerfectFit Transmission upgrades for classic muscle car restoration. With minimal cutting of floor boards and hassle free installation, you would be hard pressed to notice the difference between a Corvette with its stock transmission or a Corvette with Keisler Engineering’s A41 electronically controlled automatic transmission. The only giveaway might be that the shift quadrant has an extra place for over drive.

The A41 will fit nicely into place, with one of the only noticeable component changes being the crossmember. For all 1968-1982 Corvettes, Keisler Engineering Corporation has custom fabricated the crossmember to securely hold everything in place while allowing the muscle car restoration process maximum flexibility in choosing an exhaust system.

Another of the major components is the torque converter. Keisler offers a 1600 to 2000 rpm stall speed converter that can handle 300-500 lb-ft of torque. For maximum performance, there are also other kits available with higher stall speed converters able to handle a lot more torque.

All in all, upgrading your Corvettes transmission to a Keisler A41 electronically controlled automatic overdrive transmission will greatly increase your driving pleasure, vehicle performance and perhaps most importantly in this day and age, your gas mileage! That’s right! Don’t forget that every time you do something to make your vehicle run more efficiently and smoother, you can see that upgrade reflected in savings at the gas pump.
