Product Details


Tru-Cool Max transmission cooler by Long Manufacturing

Part number: LPD47391

GVW Rating: 40,000 GVW

BTU Rating: 45,000

Cooler size: 8.5" x 22.75" x 1.25"

The fittings on this cooler are 3/8" inverted flare.

Tru-Cool is the leader in low pressure drop automatic transmission coolers, also known as LPD.

This is the ultimate cooler for heavy towing and is a must for heavy duty applications, including racing. Heat is what kills an automatic transmission. If you want to extend the life of your transmission and avoid a premature, costly rebuild, this is very cheap insurance.

All parts and instructions are included to mount and plumb this cooler. If you want to install this cooler with upgraded hose and fittings, the 5/8”-18 threads in the cooler would allow you to convert over to AN style to use with braided or Socketless hose.  Upgraded line and fittings would need to be purchased separately.  

Retail price is $200+.

All True-Cool coolers come with a manufacturer's limited lifetime warranty. 

Alternate part numbers: OC-4739, OC-4739, LPD-4739

UPC: 621859047390

(Purchase Part number LNG-4739 for this same cooler with the thermal-bypass.)

The Tru-Cool Max cooler fixed my customer's transmission overheat where the prior installed "10,000 pound RV" cooler could not. The Tru-Cool Max design improved air flow through the radiator and dropped his engine temperature as well. The thermal bypass appears to be aircraft quality and allows quick warm up. Good mounting hardware too. In a separate class from common parts store coolers.
