Derale High Performance Cooling Pans For Seven GM Transmissions

Derale Performance is no stranger to the aftermarket, being involved with selling engine and transmission cooling products to the automotive aftermarket since the late 1960s. Recently, they’ve expanded their catalog by offering a wide array of transmission cooling pans for the most popular GM transmissions.

Official Release:

Derale Offers GM Transmission Cooling Pans

Available for the TH350 (PN 14200), TH400 (PN 14202), 700R4/4L60/4L60E (PN 14204), and 4L80/4L80E (PN 14207), these transmission pans are made from a heavy-guage steel and come complete painted in a two-stage, heat-dissipating black finish.

They’re specially designed to allow extra fluid capacity, a 1/8-inch NPT tempreture-sender port, and Derale’s patented, turbulator cooling tubes to reduce fluid temperatures 20-50 degrees fahrenheit. The pan gasket, a magnetic drain plug featuring a rubber/steel washer, and all necessary hardware is included. You can order the pan you need though the Derale Performance website linked below.
