Laymans terms

This code means that the car's computer thinks there's a problem with how one of the clutches in the transmission is working. It's like when you're riding a bike and the chain slips, making it hard to pedal smoothly.

Explanation

The transmission control module (TCM) monitors the ratio of the input speed to the output speed of the transmission. If it detects that the ratio is not within the expected range for Clutch A, it triggers this code.

Technical description

P17E1 indicates that the TCM has detected an issue with the gear ratio that involves Clutch A. This could mean that the clutch is slipping or not engaging properly, which affects the transmission's ability to shift gears smoothly.

Symptoms

• Erratic shifting

• Transmission slipping

• Check Engine Light illuminated

Common Causes

• Faulty clutch solenoid

• Worn or damaged clutch components

• Low transmission fluid
