  • Overview

    MaxTow’s Universal Transmission Test Port Extender allows access to the vehicle’s transmission test port to install a temperature sensor for extremely accurate readings directly from the source. This transmission test port sender extender features a male 1/16-27 NPT to female 1/8-27 NPT thread for the temperature sending unit. Extending the test port protects the temperature sensor from internal parts of the transmission that could cause the sensor to break and result in major damage. MaxTow includes installation instructions, a one year limited warranty and free lifetime technical support with each purchase.

    This adapter is compatible with any transmission that has a 1/16-27 NPT test port. This test port is available on Chrysler/Dodge 45RFE 4 Speed and 545RFE 5 Speed vehicles. Popular models include:
