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.
