⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect battery before working on electrical systems.
•Allow the engine to cool before working on the transmission to prevent burns.

Symptoms

•Engine RPMs increase without corresponding vehicle acceleration
•Delayed or harsh shifting between gears
•Unusual noises while the vehicle is under load
•Check engine light illuminated or transmission warning light on the dashboard
•Burning smell or fluid leaks under the vehicle

Diagnostic Steps

1
Scan the vehicle's onboard computer for error codes using an OBD-II scanner.

Check the transmission fluid level and condition (color, smell, and presence of debris).
3
Inspect the transmission fluid cooler for blockages or leaks.
4
Conduct a visual inspection of the transmission for any signs of damage or wear.
5
Test the transmission solenoids and sensors for proper operation using a multimeter.
6
Perform a road test to replicate the slipping issue under load.

Solution

Solution

1. Preparation

Gather the necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical shorts.

2. Check and Replace Transmission Fluid

Tools Required: Transmission fluid pump, funnel, catch pan.
Sub-steps:
1. Remove the transmission dipstick and check fluid level; add fluid if low.
2. If fluid is burnt or contaminated, drain the old fluid using a catch pan.
3. Replace the transmission filter if applicable.
4. Refill with new transmission fluid, following the manufacturer's specifications (consult the owner’s manual for the correct type and quantity).

3. Inspect and Repair Transmission Components

Tools Required: Socket set, torque wrench.
Sub-steps:
1. Remove the transmission pan if necessary to access internal components.
2. Inspect the transmission bands and clutches for wear; replace if damaged.
3. Check the transmission solenoids for proper operation; replace any faulty solenoids.
4. Reassemble the transmission pan and tighten bolts to manufacturer specifications.

4. Reconnect Battery and Test Drive

Reconnect the battery and start the engine.
Take the vehicle for a test drive under similar conditions to replicate the issue.
Observe if the slipping has been resolved during uphill driving.
