The current 2021 Chevy Express and 2021 GMC Savana full-size vans represent the 18th model year of their respective nameplates, offering a range of configurations to meet customers’ passenger and cargo needs. Now, GM Authority has learned that both vans will no longer come equipped with an external transmission oil cooler.
Previously, the Chevy Express and GMC Savana were equipped as standard with external transmission oil coolers when outfitted with either of the gasoline engine options. The external transmission oil cooler is tagged with RPO code V14. However, as of May 10th, 2021 Chevy Express and 2021 GMC Savana full-size vans are no longer available with the external transmission oil coolers.
It’s currently unclear as to why this component was removed from the full-size vans lineup. It could be down to a supplier issue, or alternatively, the external transmission oil cooler may have simply been deemed unnecessary going forward.
To note, the Chevy Express and GMC Savana are offered with three engine options total, including the naturally aspirated 4.3L V6 LV1 gasoline engine, rated at 276 horsepower and 298 pound-feet of torque, and the naturally aspirated 6.6L V8 L8T gasoline engine, which is rated at 401 horsepower and 464 pound-feet of torque. Both models are also available with the 2.8L I4 LWN turbodiesel Duramax, which is rated at 181 horsepower and 369 pound-feet of torque.
The 4.3L V6 LV1 gasoline engine and 2.8L I4 LWN turbodiesel Duramax are both mated to an eight-speed automatic transmission, whereas the 6.6L V8 L8T connects to a six-speed automatic transmission. While 2021 Chevy Express and 2021 GMC Savana models equipped with 4.3L V6 LV1 and 6.6L V8 L8T gasoline engines were both previously fitted as standard with external transmission oil coolers, models equipped with the 2.8L I4 LWN turbodiesel Duramax were not.
