I've got an 85 firebird with O/D. The tranny doesnt seem to shift quite right and hangs up at speeds above 50, when it seems as if it should go into O/D.. Any suggesitons ?

 

Start here: To adjust the TV Cable skip the book method and do this: Press the D button on the adjuster and loosen the cable setting. Now, have someone floor the gas pedal while you check to see if the throttle plate is open all the way. Usually they are off a little and will wiggle. Do whatever you have to do to get it open solid. Now, with the pedal still floored, press the D button and pull the cable casing (the black tube) back as hard as you can and release the button. You now have the engine, tranny and gas pedal all in sync at WOT. Mark the cable so if for some reason it gets moved you can know where to put it again. The problem with the 'self adjust method' is that it bends things and puts them permanently out of whack. It is also the full TV setting, which is theoretically what the GM method does.

 

Thanks for the info, but you'll have to explain a little more.. what is the "D" button.You mean put it into drive?
Thanks again

 

No, on the cable there is a button shaped like a D that unlocks it.

Ok...
Looking through my HANES book I see the "D" button. Now another dumb sh** quesiton. Where is the throttle plate, inside the intake? ( some call it the butterfly ) or am I way off. What is a good way to ensure its all the way open
Thanks again

 

Yes it is the butterflies but just make sure that the linkage on the throttle body stops FULLY open, no wiggle (there usually is a little). If need be, you can bend the bracket to get that last bit of wiggle out.

 

TFL,
Thanks again,
I'll try to get to in tomorrow

 

TFL,
Adjusted like you sugested and it has helped a hell of a lot. I can run up to 60-70 with no vibrations,but it still doesnt drop into overdrive by itself. Any other suggesitons?

 

Here is the "book" method w/ pics to help clarify. I have never had a problem w/ the "book" method, but I'm sure if Leo's method was worthless, he wouldn't reccomend it, so look at the pics, and try what he says. TV Cable
