Shop with Blessed Performance for the Diesel Site TRU-COOL TRANSMISSION COOLER 40,000 GVW ADD ON COOLER for your 1994-2003 Ford 7.3L Powerstroke diesel. Millions of automatic transmissions fail every year from overheating. If you tow a boat, trailer, camper or drive in Stop & Go traffic you risk overheating your transmission fluid. When your transmission fluid reaches 200° it starts breaking down.
- Transmission coolers help extend the life of your transmission fluid and can prevent transmission failure from overheating.
- At 240° varnishes form and transmission life expectancy is cut in half.
- At 260° the transmissions internal seals and rubber parts harden and major damage starts.
- Above 295° your transmission starts slipping, clutches burn out and carbon forms.
- With each 20° drop in operating temperature, your fluid and equipment life doubles.
- Installing a cooler before damage starts and by reducing the transmission fluid temperature by as much as 60° can greatly extend the life of your transmission.
- Installing a transmission cooler can prevent transmission burnout

- *In the 94-97 Ford trucks, remove your factory cooler.
