Why Buy a 2020 Chevy Tahoe Transmission from Auto Power Source
Inventory-verified is the whole point here: every 2020 Tahoe transmission on this page came out of a low-mileage donor truck, was cataloged against that truck's VIN, and is stored securely until it ships to you. Our ASE-certified technicians inspect each unit through the full gear range and check for slip, flare and harsh engagement before it is cleared for sale.
The 2020 Tahoe is the case where a guess gets expensive. Two different automatics were fitted — the 6-speed (opt MYC) and the 10-speed (opt MF6) — and the MYC trucks split again on whether the NHT tow package was ordered. Those are not interchangeable, and the option code is the fitment, not the model year. Text your VIN and we will confirm the exact code before you order.

2020 Tahoe Transmission Buying Guide
-
Read the option code before anything else. The 2020 Tahoe ships with either opt MYC (6-speed) or opt MF6 (10-speed). The code, not the year, decides the fitment.
-
Count the gears you actually have. A 6-speed and a 10-speed are different transmissions — swapping one for the other is not a bolt-in job.
-
Check for the NHT tow package. On MYC trucks we stock tow and non-tow builds separately; NHT changes the cooling and duty spec.
-
Specify 4x2 or 4x4. The two-wheel and four-wheel-drive builds differ at the tailhousing and transfer-case interface.
-
Ask for the donor VIN. We provide it on request for any Tahoe transmission in inventory so you can check mileage and history yourself.
Our ASE-certified technicians verify every one of these points against your VIN before any transmission ships.
