However, a reasonable estimate for a drain and fill is between 6 and 8 quarts. This is only an approximation.
To find the exact amount:
* Consult your owner's manual: This is the best source of information for your specific vehicle. It will list the correct capacity and the recommended procedure.
* Check the dipstick: If your transmission has a dipstick, check the fluid level *after* the engine has been running for a few minutes to allow the fluid to warm up. This will tell you how much fluid to add if topping off, but not the total capacity.
* Look up your specific transmission type: The capacity can vary slightly depending on the transmission model (e.g., Allison 1000, etc.). Once you determine the transmission type, search online for the fluid capacity for that specific transmission. Many automotive forums and websites provide this information.
Important Considerations: Never assume. Always refer to your owner's manual or consult a trusted mechanic for the precise amount of ATF needed for your vehicle. Using too much or too little can damage your transmission.
