Drivable short-term, but fix now to avoid damage.
This code means the transmission fluid temperature rose above its safe limit. Causes include low or old transmission fluid, a clogged cooler, heavy towing, a failing pump, or internal transmission problems. Driving with overheated fluid can damage the transmission, so repairs usually start with checking the fluid level and condition and inspecting the cooling circuit.
$120 – $1500
Varies by vehicle and root cause.
Only briefly if you must. Continuing to drive with an overheated transmission can cause serious damage, so let it cool and get it checked soon.
It ranges from around $120 for a fluid service or sensor to $1,500 or more if the cooler or transmission needs major work. A diagnosis is needed to know the cause.
Yes. Overheating is one of the leading causes of transmission failure, so this should be addressed quickly to avoid a costly rebuild.
Common reasons are low or worn-out fluid, a clogged cooler, or heavy loads like towing. Fresh fluid and a working cooling circuit usually keep temperatures in check.
