No CEL. I'll take a look at that though. What's the plug look like?

thanks!

Grey plug. The wiring harness for it comes over the top of the trans in a heat sock and it goes straight down into the trans. There is two bolts to take off the little heat sheild by it and it gives you room to access it as its pretty tight.

ATF there just means the "O" ring is leaking.
ATF in a non conductor of electricity.

The black ring around the plug is the "O" ring:

Oil can not short anything.

Don't know what caused it, I just know what codes it kept throwing and what fixed the problem and it was doing the same thing this guys is.

Blueray has not posted his codes but it might help if he did.
If you had two coils burn up at the same time that would be a little hard to believe.
Maybe you had very dirty ATF and the those valves stuck open.
Those coils have battery voltage on one side and the computer grounds the other side.

When any solenoid coil burns up it is from too much current going through them.
Did you have a bad computer or wiring shorting to ground also?
Maybe your alternator started putting out too high of voltage to cause the high current.

My CEL isn't on. I haven't tried to figure out how to short the connector and see if there are any stored yet. it will store codes, correct? though I've had the battery disconnected for 24 hours which may have erased them?

Yes you have lost the codes that may have told you your problem by unhooking the battery.

So you need to drive it until it does it again and then check the codes stored in CM.
First you do the KOEO electrical test and then you would have a pause and then see a one blip and then another pause and then you get the CM codes to flash out.

You can go to this link for more information:

Finally took to transmission shop, solenoid was bad for sure. They replaced that and when they drove it, found that third gear was out as well. They're not sure what it needs until they pull transmission out. Ugggghhhh ...

thanks for the suggestions!
