Changing the A/T Fluid (ATF)

CAUTION: If using the vehicle for towing, the A/T fluid must be replaced as specified. Refer to [INTRODUCTION OF PERIODIC MAINTENANCE ].

Drive the vehicle to warm up the A/T fluid to approximately 80 °C (176 °F).
Stop the engine.
Remove the A/T fluid level gauge.
Drain the A/T fluid from the drain plug hole, then install the drain plug with a new gasket. Refill the transmission with new A/T fluid. Always refill with the same volume as the drained A/T fluid. Use the A/T fluid level gauge to check the A/T fluid level as shown. Add A/T fluid as necessary.

Drain plug: Refer to Transmission Assembly: Component .
- To flush out the old A/T fluid from the transmission oil coolers, pour new A/T fluid into the A/T fluid charging pipe with the engine idling and at the same time drain the old A/T fluid from the auxiliary transmission oil cooler hose return line.
- When the color of the A/T fluid coming out of the auxiliary transmission oil cooler hose return line is about the same as the color of the new A/T fluid, flushing out the old A/T fluid is complete. The amount of new A/T fluid used for flushing should be 30% to 50% increase of the specified capacity.
A/T fluid grade and capacity: Refer to [ RECOMMENDED FLUIDS AND LUBRICANTS [FOR USA AND CANADA] ] (United States and Canada) and [ RECOMMENDED FLUIDS AND LUBRICANTS [FOR MEXICO] ] (Mexico).
CAUTION:
- If SUZUKI approved Matic S ATF is not available, SUZUKI approved Matic J ATF may also be used. Using automatic transmission fluid other than SUZUKI approved Matic S ATF or Matic J ATF will cause deterioration in driveability and automatic transmission durability, and may damage the automatic transmission, which is not covered by the SUZUKI new vehicle limited warranty
- When filling the transmission with A/T fluid, do not spill the A/T fluid on any heat generating parts such as the exhaust manifold.
- Do not reuse the drain plug gasket.
Install the A/T fluid level gauge and tighten the A/T fluid level gauge bolt to specification.
A/T fluid level gauge bolt: Refer to Transmission Assembly: Component .
Drive the vehicle to warm up the A/T fluid to approximately 80 °C (176 °F).
Check the fluid level and condition. If the A/T fluid is still dirty, repeat steps 2 through 6.
