🔧 Transaxle Fluid Change - Drain and Fill

Your Camry uses a hybrid transaxle, not a traditional automatic transmission. This service replaces the fluid in the transaxle case by draining it and refilling to the correct level, which helps protect the hybrid drive components and keep shifting smooth.

Difficulty Level: Intermediate | Estimated Time: 1.5-2.5 hours

• Set the cover and hardware aside in order.

Step 2: Locate the fill plug and drain plug
