Green ATF?

I was doing some work to get ready for my flexplate swap, and when I disconnected the transmission cooler lines the ATF that dripped out had a greenish-gray color. My truck has the original cooler, so it isn't antifreeze contamination.

I have seen ATF get dark and smell burnt, but never turn green. The truck has 206,000 miles and the transmission has been shifting fine, but I have only been driving it for about 6 weeks.

I'm going to change the fluid after the transmission goes back in, but is there anything else that should be looked at? Has anyone ever seen this type of discoloration?

Chris

I have not ever seen trans fluid like you describe. Hopefully, a fluid change will be all you need.

Here is a sample in a jar. This is what it looked like in the drain pan last night:



Here is the same stuff on white card stock this morning:



I think my eyes were playing tricks on me last night. What looks gray-green in the jar is more like reddish brown on paper.

I'm kinda relieved, but it's getting new fliud and a filter for sure.

I'm not sure if the Scheafers is green for ATF, but it is for the oil.

I had oil draining the other day when I changed some in my fathers truck and it looked blood red coming out even though it was black and... well way over mileage.

GREEN ATF

G'day Fellas,

Not sure if you get it over there but I use Castrol Transmax 'Z' ATF in my 4R100, Steering and Transfer case.
It is a distinctive 'Green' in colour.

It was excellent when I flushed out the original dino Red coloured fluids. As soon as no Red showed and nice clean Green started to flow, I new I'd done a good flush out and only had the Fully Synthetic ATF in the system.

It is Castrols recommended fluid for the 4R100 Trannys out here in Aussie.
It's good stuff.

Cheers,
Reg

That is nearly the same color my fluid was when I flushed. It does look green in the vile.

One other thing I was going to mention was leak detector, although I have never seen it used in a transmission I am sure it very well could be.

How many miles on the fluid, and what kind of driving do you do? Towing, etc...

206K on the odometer, don't know when it was last changed (if ever). It's an F350 4X4 DRW former ambulance that I converted into a utiltiy body. 12.5K GVWR, no towing.
