Transmission Wire Harnesses by Rostra Transmission
Rostra Precision Controls Inc. proudly introduced a new and innovative line of internal and external transmission wire harnesses in 1997. Since then, our product offering has expanded to over 35 part numbers covering a wide range of domestic and import vehicles. We drew on our vast experience and knowledge of cruise control application to create the highest quality, most durable, easiest to install harnesses available to today's technicians.
The transmission wiring harness is one of the most critical components within today's complicated electronically controlled units. Electronic signals control nearly every function within the transmission. The wire harness conveys these signals to the solenoids and sensors. Any interruption will result in failure. We urge all technicians to replace the harness and all solenoids with each complete overhaul.
As with all Rostra products, we manufacture these units in the United States under strict QS-9000 quality requirements. Each harness is 100% tested for fit, form and function before leaving our facility. These procedures insure that you will receive the finest parts available for a quality-rebuilt transmission.
Our Engineering staff has made several product enhancements for improved durability and longer life. We have also consolidated many original equipment part numbers to reduce inventory-carrying costs and simplify the order placing procedure. These consolidations assure the shop owner that they are going to receive the correct part each time they place an order. We offer a broad line of internal wire harness assemblies, external wire harness, wire harness repair kits and connectors. Ask for Rostra by name.
