Earlier today, I was washing my TL from top to bottom and drove it into my garage to dry it off. I notice there was a purple "fluid" type puddle on my driveway. I went to look underneath the car and I see water dripping from the splash shield (transmission area). So I took the splash shield off and the left part of the transmission had some purple "coating?". I checked my transmission fluid, power steering and brake fluid, coolant and everything seems fine. Does anyone know what can it be?

Can it be an undercoating to protect undercarriage?

• Engine oil is Pennzoil Platinum
• Transmission fluid is Redline D4 ATF --changed 1.5 years ago
• Power Steering and Brake fluid is OEM Honda fluid

*Right is the transmission fluid colour.

 

Some windshield washer fluid can be purple.

 

WOW, I totally forgot about the windshield wash fluid, Thanks!
