TQ's lockup or non?
i havent been on here much cuz i been so busy working on car
and getting the kinks out
anywayz, i got a 3.1 700r4 auto, does it have lock up or non-lockup Torque Convertor? im just curious
and also? arent the 700R4's electronically controlled to shift gears and all that?
took it to the track again ran open headers... still only few tenths better then stock,. . guess i shoulda took a few things out

Quick tip on your car...it's a 91, so it's an RS. They eliminated the SC name all together by that time. Just figured I'd tell you since the sig caught my eye. 
To answer your questions.. Ours have lockup converters. Nearly all factory cars come with lockup converters. Saves gas mileage. Notice how your car seems to have 5 gears? That extra one is the torque converter locking.
These transmissions are HYDRAULICALLY controlled...there are no electronics to them whatsoever. The shift points and firmness is all controlled with the TV cable, which is linked to the throttle blade. Electronic transmissions didnt start until 93 and up I THINK, but don't quote me on that. But SOMETIME during Gen 4.

A bit more info; shift points and firmness is not controlled by the TV cable. The TV cable affects the line pressure (fluid pressure) inside the trans. And in turn, the line pressure affects shift points and firmness- to an extent. The major function of the TV cable is to keep enough pressure inside the trans so the clutches don't run dry and burn up!! 
Just figured I'd give the "rest" of the story as far as that goes

As usual, Tom chiming in to correct my inaccuracies. Thanks Tom. 
Funny side note...I don't know why....but all my Ford friends refuse to believe that they're actually called 'TV cables'. They all refer to them as 'kickdown cables', and when I try to explain that a TV cable and a kickdown cable are not the same, they tell me I'm an idiot and that a TV cable is for a TV not a transmission. Arrgh, I hate people.
