MotorVac's TransTech IV combines both in-line and dipstick capabilities allowing for the two most common methods of automatic transmission fluid (ATF) exchange from a single machine. With both services together in one cabinet, TransTech IV occupies reduced floor space with minimal investment, while providing service to a wider variety of vehicles. The machine has a drain pan feature; a transmission cooler flush feature; patented level synchronization, which ensures the transmission cannot be under- or over-filled. There is an automatic bypass that ensures the transmission will not run out of fluid during the exchange process. The machine also has a high-volume pump for rapid and efficient service, and comes with a complete adapter kit.
