Transmission Shifter



We’ve been making performance shifters in the United States since 1989, and they are being used by racers across the country and around the world. We have three models of shifters, the Kwik Shift I is our premier manual shifter, the Kwik Shift II is a lower-cost alternative, and the PowerShift is our top of the line hands-free air shifter.

Transmission Instruments is your source for rebuilt and refurbished WTECII and WTECIII ECU's and Shifters for Allison Automatic Transmissions (Models: MD3060, MD3560, HD4060, and HD4560 etc). These push-button control boxes are found in RV's, medium-size trucks, buses, service/utility vehicles, and many other pieces of equipment fitted with the tough and time-honored Allison transmissions.

What We Offer

We can often repair your ECU. Call us for details and please have your trouble codes handy. (Sorry, Transmission ECUs only. We don't repair engine management systems.)
Our turn around time for ECU rebuilds is typically 2 to 3 business days. Put your contact information ( name, phone number and e-mail address ) directly on the unit.

Why Use Us

The WTECII and WTECIII ECU's and shifter modules are expensive to replace, running between $3500.00 and $4000.00. Remote shifters also running at $2000 and Shifters at $1000. In-shop rebuilding is impractical and often results in a short-lived repair. Transmission Instruments specializes in the ground-up rebuild and refurbishment of these devices.

Different Than A Repair Kit?

Very. The repair kits replace certain wear-prone parts but the printed circuit board - the backbone of the device, is not included. For the serviceman in the pit, this means wasting time and money by sending the vehicle to a body shop to perform 'electrical' repairs. Even the body shop mechanic will find this time-consuming rebuild will result in a less than favorable fix. For example, the push buttons are integrated into the printed circuit board (PCB), and cannot be replaced, however, with our proprietary restorative processes, they can be repaired. Often there is damage to the PCB itself, which is something no transmission shop, body shop, or field service mechanic is outfitted to repair. We specialize in these repairs, and take these shifter boxes down to the component level, restoring them to a better than new condition. The shifter or ECU you send in for rebuilding with us will probably outlast the remaining service life of the equipment it came from.

What Is Required?

We only need your shifter or ECU core. Make a copy of all the labels on your ECU for your records, in case it gets lost in the mail. Pack the unit very well, especially around connectors! Use extra packing material where necessary to make sure all connectors are protected. Sometimes we get a unit with broken connectors because it’s not packed correctly, which can result in additional repair charges. Please e-mail us your tracking number.
