The Problem

The 2019 to 2021 Toyota Tundra trucks are missing a crucial element – the transmission cooler – a decision that proves to be a notable oversight.

We couldn't find official documentation from Toyota explaining the specific reasons for deleting the transmission cooler from the 2019 to 2021 Tundra. However, automakers often make adjustments to vehicle features for various reasons, including cost-saving measures, redesigning for improved efficiency or performance, or responding to changes in regulations or consumer preferences. Without an official statement from Toyota, it's challenging to pinpoint the exact rationale behind this specific change.

The absence of a transmission cooler in the Tundra trucks poses several potential problems:

  • Overheating: Without proper cooling, transmission fluid can overheat, leading to decreased lubrication efficiency and accelerated wear on transmission components.
  • Transmission Fluid Degradation: Excessive heat can cause transmission fluid to degrade faster, diminishing its effectiveness in lubricating and cooling the transmission, potentially leading to performance issues and maintenance needs.
  • Decreased Towing Capacity: Operating without a transmission cooler under heavy loads can increase transmission temperatures, risking damage and reducing the truck's towing capacity.
Overall, the absence of a transmission cooler on the 2019 to 2021 Toyota Tundra trucks can lead to performance, reliability, and maintenance issues.
