Been thinking about using dye to check for specific leaks before I attack the rear main seal and oil pan gasket. Since that area can be one of three different fluids for leaking given the coolant plugs, oil seals and plugs and proximity to tranny thought it would be good to confirm what we 'think' we know before we go through with the process.

Here's my question though. Obviously, I am looking for leaks from potentially three different fluids (coolant, engine oil, tranny oil). All I find during my online searches is the usually green glowing dye. I'm trying to find out if there are different color dyes so that I could put a different one in each fluid for more specific answers.

Anyone know anything about it?

I know nothing of the dyes.
However If I were trying to see which one of the three were leaking I would likely spend some time with a rag and a degreaser and clean up as much as I could reach, then once the drippings return a white paper towel should show brown for engine oil, red for ATF and greeninsh for coolant.

yup. we've done the clean and observe drip test. for the most part pretty sure it is only oil out of the pan gasket or rear main but that area could be some tranny fluid mixing in that we can't see because it doesn't drip all the way down. though we don't notice the level going down really but thought we'd be thorough none the less.
