Auto Trans Fluid colouring?

My trans fluid is a clear browny colour rather than the standard red. I originally thought it was dirty or burnt but it looks so clean I think it must be some sort of performance fluid.

Anyone seen this before?

 

I've never seen fresh trans fluid that colour :thumbsdown:, but not all trans fluid is red. Mine is green

 

Clear brown due for service.

 

Brown = old/burnt/replace.

 

Thanks guys

When I first looked at it, I thought it was engine oil, but it smells like trans fluid.
I'll book it in for a trans service.
