700r4 transmission (tcc plug???)
I bought my bird in november of last year
and when i jacked the car up to my surprise (along with the rotted out floorboards, split y pipe and busted brake lines) a 4 prong connector was just sitting on top of my tranny and not even plugged in 
(those cheep *** holes
)
How major is this?
if i plug this in will i stall the car?
how bad is this hurting my MPG's (its a 3.1)?
HEEEEEEEEEEEEEEEEEEEEEEEEELP?

You need it plugged in to keep the temperature of the fluid down while you're cruising in overdrive.

Well, if the TCC solenoid was worn and stayed locked when coming to a stop, it may have been their cheap fix. That's okay to do on a 200-4R. It's not okay to do on a 700-R4 that's not modified to do it.

I have a somewhat related question. My TCC doesn't lock up at all. The only wires I see are connected into the VSS on the side of the tranny. Is that the same connector for the TCC solenoid, or should I keep looking?

----------
Different connector, further forward, facing upwards just above the pan.
