Ok, So I have had a cracked radiator for a while and after I finally put in my replacement, I went to do my routine fluid check and I had a frothy white foam on my transmission dipstick. I can't imagine that my new radiator has a leak between the coolant and transmission walls... I supposed anything could be defective though.. I replaced the fluid, made sure my levels were good and the white froth was still there, but not as thick as it was prior to the change. I have had this car for about 3 months and it looks like the transmission has never seen new fluid. No slippage, some grit to the old fluid that I drained out though. Any thoughts?? --2001 Honda Civic LX
