The shifter cable is a mechanical linkage that connects the gear selector to the transmission. If the cable is stretched, worn, or damaged, it can cause the transmission to shift into the wrong gear or not shift at all.
- Failed transmission sensor
The transmission sensor is an electronic device that monitors the speed, position, and temperature of the transmission. If the sensor is faulty, it can send incorrect or erratic signals to the transmission control module (TCM), which can cause the transmission to shift harshly or erratically.
- Faulty transmission control module (TCM)
The TCM is the computer that controls the transmission. If it is malfunctioning, it can also possibly lead to hard shifts.
2. Erratic Shifting and Slipping
Erratic shifting and slipping problems in 2017 Chevy Colorado Transmission are issues that affect the performance and safety of the vehicle. They can cause the transmission to delay, jerk, or fail to engage gears properly, resulting in loss of power, fuel efficiency, and control. Here are some possible causes and solutions for these problems;
- Low transmission fluid
If the fluid level is too low, the transmission may slip or shift erratically due to insufficient pressure or friction.
- Faulty transmission control module
The transmission control module (TCM) is the computer that controls the transmission’s operation, including the timing and pressure of the gear shifts. If the TCM is malfunctioning, it may send incorrect or inconsistent signals to the transmission, causing it to shift erratically or slip.
- Worn-out clutch or pressure plate
The clutch and pressure plate are parts of the torque converter, which transfers the engine’s power to the transmission. The clutch engages and disengages the torque converter, while the pressure plate applies and releases the clutch. If the clutch or pressure plate are worn out, they may not be able to hold the torque converter firmly, causing it to slip or shudder.
3. Burning Smell
Bad smell problems in 2017 Chevy Colorado Transmission are unpleasant odors that may come from the transmission fluid or the air conditioning system. Here are some possible causes and solutions for these problems;
- Burnt transmission fluid
Transmission fluid is essential for lubricating and cooling the transmission components, as well as providing the hydraulic pressure needed for gear shifts. If the fluid overheats, it may degrade and burn, producing a foul smell that resembles rotten eggs or burnt rubber. This may indicate that the transmission is slipping, overheating, or failing.
- Moldy air conditioning system
The air conditioning system in the Chevy Colorado may accumulate moisture, dirt, and bacteria, which can cause mold and mildew to grow inside the system. This can produce a musty or sour smell that is noticeable when the AC (or heater) is on. This may also affect the air quality and cause health problems for the occupants.
