4L60-E Case Electrical Connector O-Ring Color?
After a few days without driving, the case connector leaks because of converter drainback. I'm weary of the mess it makes.
I have it on the lift, I have identified the leak source. It is the o-ring, not the wire terminals.
I went through my broken seal kits and found a green O-ring in both a 60E and an 80E kit. Both transmissions have this connector. But my recollection is that it is a blue O-ring, and I don't have any blue ones. (I thought of my ATSG book, but it is for 4L60, not the E. I don't have an ATSG for the E.)
I have everything else to change it, but the parts house is a ways away. If it is the green one, I'll do it this afternoon. If it is the blue one, I'll let it leak for now, and park it in the dirt if its going to sit.
Anyone remember which color the case connector o-ring is?
Thanks in advance for any help.

Update:
It is green. So I had one.
~~~~~~~~~~~~~~~~~~~~~~~~~~
For C4, this would only apply to 94-96. And I'm sure the exhaust and cat converters are in the way. I wasn't working on a C4, but the connector itself is the same deal.
The old o-ring was loose, like it had shrunk. I don't think the quality of the stuff in the aftermarket transmission kits is all that great. This o-ring was 3 years old from when I replaced the wire harness in 2021. It was leaking pretty badly.
There are 4 tangs that hold the connector shell up into the case. With the exhaust in the way, and not really being able to see up there, it was a bitch. I've removed these with the case on the bench, no biggie. But I struggled for about 30 minutes and couldn't get the thing loose. I was contemplating breaking the connector to get it out and go buy a new harness for $50. And then it occurred to me:
Get a hose clamp and squeeze all 4 tangs simultaneously. It took 2 tries. Push the connector body up, hold it there, make sure the clamp is around all 4 tangs (use braille, you can't see them), tighten the clamp snug. The shell pulled straight down on the second try. Cool.
It is green. So I had one.
