Thumbnail Filmstrip of 7.3 OBS Powerstroke Transmission Cooler Tru-Cool 750-47391P5 Images
1994-1997 OBS CAN INSTALL USING THE SUPPLIED PARTS - simply remove your existing cooler, install the new cooler in the same location, and connect to existing lines.
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.
Tru-Cool Transmission oil cooler kits contain:
- Cooler
- Hose
- Fittings
- 2 styles of Mounting Hardware - Quick connect nylon straps & steel mounting
- Installation instructions - nonspecific to application. (NO special tools required)
*Additional Hose and Mounting bolts may be needed for your application.

Would’ve been very nice to specify somewhere on the description of the product that this doesn’t include the thermal by-pass
Kinda bought it because of the by-pass but turns out it doesn’t come with it ?
A bit disappointing
Note From Store Owner: We checked this product. The picture is accurate to the product and in the description inclearly states what is included. Sorry you missed it.
