Part #: MMTC-T1-21

Heat is the biggest threat to your transmission's longevity and performance. Whether your 2021+ Chevy Tahoe or GMC Yukon is hauling the family camper, towing weekend toys, or taking long summer road trips, keeping your transmission cool is essential for lasting performance and peace of mind.--Mishimoto's direct-fit transmission cooler is engineered with a significantly larger tube and fin core that is 266% bigger than stock and maximizes cooling efficiency. This larger capacity reduces transmission temperatures and stress, helping extend the life of your transmission while maintaining reliable operation under heavy loads. Sturdy internal strutted tubes offer greater pressure resistance and protection against chassis flex.--Installation is straightforward with factory-compatible connections, and included bolts, plus a billet driver's side bracket with slotted holes for precise adjustment. There's plenty of clearance all around, and it can be installed without removing the grille, saving time and effort.--Designed, engineered, and tested in the USA, this genuine Mishimoto cooler features a robust powder coat to protect against corrosion and road debris. Backed by Mishimoto's Lifetime Warranty, it's a clean, reliable upgrade that eliminates the risks of reusing your stock cooler and keeps your transmission running cooler for longer.
