The 2002 Toyota Celica, a sporty coupe known for its performance and handling, requires regular maintenance to keep it running smoothly. One essential task is changing the manual transmission fluid. This guide provides step-by-step instructions for changing the manual transmission fluid in a 2002 Toyota Celica GT.
While this guide focuses on the GT model, the process is similar for the GTS, with minor differences in fill plug location and fluid capacity. Always consult your owner’s manual for specific recommendations for your model.
Necessary Materials for a 2002 Toyota Celica Fluid Change
Before starting the process, gather the following materials:
- Gear Oil: Approximately 2.3 liters of 75w90 GL4 or GL5 gear oil for the GTS, and 1.9 liters for the GT. Redline MT90 is highly recommended due to its compatibility with the Celica’s synchros. Do not use Redline 75w90NS. Full synthetic oil is generally preferred for its superior performance and longevity.
- Tools: A 10mm, 17mm, and 24mm socket wrench, a funnel, a length of tubing for the funnel, and a large drain pan.
- Optional: New drain and fill plug gaskets.
2002 Toyota Celica Manual Transmission Drain and Fill Procedure
Step 1: Prepare the Vehicle
Park your 2002 Toyota Celica on a level surface, engage the parking brake, and allow the engine to cool down completely.
Step 2: Access the Transmission
Locate the driver’s side plastic engine cover underneath the car. This cover protects the transmission and needs to be removed to access the drain and fill plugs.

Step 3: Locate and Loosen the Plugs
Identify the fill and drain plugs on the transmission. On the GT, both plugs are 24mm and the fill plug is located to the left of the wiring harness.
Loosen the fill plug first, then the drain plug. This will ensure that the transmission can drain properly. Have your drain pan ready to catch the old fluid.
Step 4: Drain the Old Fluid
Remove the drain plug completely and allow the old transmission fluid to drain into the drain pan. This may take some time.
Step 5: Reinstall the Drain Plug
Once the fluid has finished draining, clean the drain plug and install a new crush washer if necessary. Tighten the drain plug to the manufacturer’s specified torque.
Step 6: Fill the Transmission
Insert the tubing attached to the funnel into the fill hole. Pour the new transmission fluid into the funnel until it starts to overflow from the fill hole. This indicates that the transmission is full.
