Perma-Cool Frame Rail Transmission Coolers

5.0 out of 5 stars 3 Customer Reviews

Perma-Cool frame rail transmission coolers are perfect if you don't have much available mounting space, or if you just want a hideaway transmission oil cooler. They are easy to install and work excellently on your street rod or custom vehicle. These two-pass coolers are compact yet powerful, and mount in tight quarters or out-of-sight underneath your vehicle. They feature 1/2 in. diameter tubes with Turbulator cooling fins for maximum heat transfer, and they come with hose, fittings, and mounting hardware, unless otherwise noted.
