Transmission Vibrates

The majority of the time, when the 2015 Silverado 6 Speed transmission is cold, it vibrates a lot since the car is moving slowly up a hill. This happens as a result of the vehicle’s low power output, which also lowers the vehicle’s capability.

Transmission noise

When the plastic ball valves in the 2015 Silverado 6-speed transmission are distorted, pressure loss may occur, which can cause the gear/transmission to fall out and generate noise.

1-2 Hard Change

The 2015 Chevrolet Silverado truck’s regular transmission problem is an erratic, difficult 1-2 change. Engine bogging is frequently present along with this issue. The torque converter clutch, which is used when the transmission shifts, might be to blame.

Transmission slippage

The accelerator pedal sensor may not function properly due to a short transmission line, which could ultimately result in the car not starting.

As a result, it won’t be able to communicate with various other mechanisms, which is what its crucial duty entails.

This will cause the accelerator pedal to stop working properly, which will limit the driver’s ability to accelerate.

How long will the 2015 Silverado transmission last?

Your transmission will likely need to be replaced between 150,000 and 200,000 miles from now, depending on maintenance.

The K2s now have thermostats, which naturally increase the fluid temperature for maximum efficiency while reducing wear and tear. In general, the GMT900 6L80s appear to need overhauls after 160K miles.

Although they are designed to withstand extreme heat, if they are, the fluid needs to be changed sooner. On the highway, my car, which has the factory external cooler, never reaches the minimum temperature needed to verify the fluid level.

The life expectancy also depends on how the manufacturing worker feels on that particular day. I’ve seen Chevy vehicles live the easy life and have the trans die at 60–70K miles, as well as trucks that have been through hell and back and still had the original trans.

In my opinion, the type should be between 150 and 200K miles. 130-150K is considered typical if you live in a region with a lot of frigid winters or a lot of summer heat, such as higher elevations or southern states.
