Wrench set (for fluid pan removal)
Fluid catch pan
Torque wrench (for reinstallation)
New transmission fluid (recommended type: 3309)
Transmission filter kit (if necessary)

Repair Instructions

Step 1: Address Fluid Issues

Fluid Change: If the fluid is burnt or low, perform a transmission fluid change:
- Lift the vehicle securely using a jack and jack stands.
- Place a fluid catch pan under the transmission pan.
- Remove the transmission pan bolts and carefully lower the pan.
- Clean the pan and replace the filter if applicable.
- Reinstall the pan with a new gasket and torque the bolts to manufacturer specifications.
Refill Transmission Fluid:
- Using a funnel, refill the transmission with new fluid through the dipstick tube. Ensure the correct type and amount are used.

Step 2: Repair Cooling System

Clean or Replace Transmission Cooler:
- If clogged, clean out the transmission cooler lines and cooler. If damaged, replace the transmission cooler.
Check/Replace Temperature Sensor:
- If the temperature sensor is found to be faulty, disconnect the battery, remove the sensor, and replace it with a new one. Reconnect the battery.

Step 3: Electrical Inspection

Repair Wiring: Fix any damaged or corroded wiring and ensure all connectors are secure.
Reset the Transmission Control Module: After repairs, disconnect the battery for a few minutes to reset the transmission control module.

Testing After Repair

Road Test: After completing repairs, take the vehicle for a test drive to monitor transmission performance.
Monitor Temperature: Check if the transmission temperature warning light remains off and ensure the transmission operates smoothly without slipping or delayed engagement.
