Car Rental Companies Wiring Transmission to Disable Car

Introduction

Car rental companies are increasingly using a controversial practice to disable cars that are reported stolen or overdue. This practice, known as “transmission wiring,” involves wiring the transmission so that it will not shift out of park. When the car is reported stolen or overdue, the rental company can remotely disable the car by sending a signal to the transmission wiring.

How Transmission Wiring Works

Transmission wiring is a relatively simple process. A wire is connected from the transmission control module (TCM) to the transmission shift lever. When the shift lever is moved into park, the wire is grounded, which prevents the TCM from sending signals to the transmission. This prevents the car from shifting out of park.

Why Car Rental Companies Use Transmission Wiring

Car rental companies use transmission wiring for a number of reasons. First, it is a relatively inexpensive way to disable a car. Second, it is a very effective way to prevent a stolen car from being driven. Third, it can be used to disable a car that is overdue.

The Legality of Transmission Wiring

The legality of transmission wiring is somewhat unclear. In some states, it is considered to be a form of theft. In other states, it is considered to be a civil matter. However, there is a growing body of case law that suggests that transmission wiring is legal.

The Pros and Cons of Transmission Wiring

There are both pros and cons to transmission wiring. On the one hand, it is a very effective way to disable a stolen car. On the other hand, it can also be used to disable a car that is overdue. Additionally, it can be difficult to remove the wiring after it has been installed.

Conclusion

Transmission wiring is a controversial practice that is increasingly being used by car rental companies. While it is a very effective way to disable a stolen car, it can also be used to disable a car that is overdue. Additionally, it can be difficult to remove the wiring after it has been installed.
