Laymans terms

This code means that the filter in the car's transmission is getting old and might not be working well anymore. It's like when a vacuum cleaner's filter gets clogged and needs to be cleaned or replaced.

Explanation

The transmission fluid filter is responsible for keeping the transmission fluid clean by filtering out debris and contaminants. When the filter deteriorates, it can no longer effectively filter the fluid, potentially leading to transmission issues.

Technical description

The P088A code indicates that the transmission control module (TCM) has detected a problem with the transmission fluid filter. This could be due to the filter being clogged, damaged, or otherwise compromised, which can affect the performance and longevity of the transmission.

Symptoms
