I'm a dope, officially. Two sets of wires, running along the left side of the intake, ending with large washers, calling out to be grounded - weren't. Bolt on the back of the left head, w/braided ground strap attached, when the two wires from the intake manifold loom were bolted down to the back of the left head - SHAZAM!

No more blinking Check Trans Light.

I saw that at like 1:30 this AM, but wasn't ready to go there.

Now you know, check all your grounds!

91 Trooper, now with tasty 3.4 goodness!
