Subject: [oletrucks] Turbo 400 lockup converter?

>Just aquired a turbo 400 in real good shape and I'm gonna put it in my '79

>connection on the outside of the case going to a solenoid on the rear of
the

is

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

>Also, My bud that ran this tranny in his car said the only problem he had

this

to

>This free turbo 400's a funny thing. Turns out only short wide pickups 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
