Final answer:
The fluid color that indicates an automatic transmission/transaxle leak is typically red. Fresh transmission fluid is bright red, while older fluid may be a darker red.
Step-by-step explanation:
If you're trying to identify the fluid from an automatic transmission/transaxle leak, you would typically be looking for a red color.
Fresh transmission fluid has a bright, transparent red hue, while older fluid may take on a darker, brownish-red color but should still retain some of its reddish tint. If the leak is indeed transmission fluid and it appears red, that would likely indicate a leak in your vehicle's automatic transmission or transaxle system.
It's important to address such leaks promptly, as they can lead to transmission issues if the fluid level drops too low.
