PPE Bar & Plate Transmission Cooler | 2001–2005 Silverado/Sierra 2500HD 6.6L & 8.1L

🔥 Keep your transmission running cool — even under pressure.

Excessive heat is the #1 enemy of transmission longevity, especially in modified or hard-working trucks. Whether you tow heavy, run performance tuning, or push your rig at the track, the PPE Bar & Plate Transmission Cooler is your frontline defense against heat-soaked failures.

Designed as a direct-fit upgrade for 2001–2005 Chevrolet Silverado and GMC Sierra 2500HD trucks with either the 6.6L Duramax or 8.1L Vortec engines, this high-performance transmission cooler offers 2.8x more cooling capacity than the factory unit. That means cooler fluid temps, better shifting, and a dramatically extended transmission lifespan.

✅ Bar & Plate Construction – Far superior to OEM tube & fin coolers. Internal square-pattern fins and external louvered fins maximize fluid cooling and airflow efficiency.
✅ Bolt-On Install – No cutting, no welding. Uses your existing factory mounts for a hassle-free upgrade.
✅ Built for Big Power Builds – Handles the extra heat from upgraded valve bodies, converters, and transmission tunes with ease.
✅ Heavy-Duty Design – Made from high-quality aluminum and backed by PPE’s limited lifetime warranty.
✅ Quick-Connect Fittings – Includes new 7/8-14 trans line fittings for fast and secure installation.

Why Upgrade Your Transmission Cooler?

When you increase mainline pressure through performance mods, your trans runs hotter—sometimes much hotter. Stock coolers just can’t keep up. The PPE Transmission Cooler ensures proper heat dissipation even under max load, protecting clutches, solenoids, and hard parts from premature failure.
