Laymans terms

The car's computer is noticing that a part inside the transmission is not working as fast as it should. Think of it like a toy car that doesn't move as quickly when you push a button.

Explanation

This code indicates that the transmission control module (TCM) has detected an issue with the apply time of the transmission friction element G, meaning it is not engaging or disengaging within the expected time range.

Technical description

The P273A code is triggered when the TCM detects that the apply time for the friction element G in the transmission is outside the acceptable range. This can be due to mechanical issues, hydraulic problems, or electronic control malfunctions.

Symptoms

• Delayed or harsh shifting

• Transmission slipping

• Check Engine Light on

Common Causes

• Faulty transmission solenoid

• Low transmission fluid level

• Internal transmission failure
