I believe the wire is part of the kick down solenoid and goes up to the
carburetor where the switch is activated by throttle position.

Subject: [oletrucks] Turbo 400 lockup converter?
>Hey everyone,

>Just aquired a turbo 400 in real good shape and I'm gonna put it in my '79
>silverado in place of the 700R4 until I can rebuild the 700R4. I was giving
>the tranny a thorough inspection and filter change and found a single wire
>connection on the outside of the case going to a solenoid on the rear of
the
>valve body. What is this? Is it a converter lockup or? I think the tranny
is
>a 78, but not sure. The tranny has been behind a 600 horse 383 for some
4000
>or so miles, seen 20-30 12 second quarter runs and general abuse without
this
>connection hooked up. If this is a lockup which wasn't hooked up, could the
>tranny have been damaged? The fluid looks awesome with a spotless pan.

>Also, My bud that ran this tranny in his car said the only problem he had
>with the tranny was that it would never wind out past 5 grand before
>upshifting to second (engine's built to turn 7500). My 350 is only built to
>turn 6500. A 5 grand shift into second gear would be fine by me, but if
this

to

>This free turbo 400's a funny thing. Turns out only short wide pickups with
>big blocks got the 400's. That means driveline's for a short wide with
turbo
>400 are rare as chickens teeth. This free trannie's costing me a $200
>driveline. Atleast I don't have to dick with that stupid TV cable on the
>700R4 for a while though. Thanks,
