Tranny Problems

I am experiencing some slippage from first to second and second to third.If I have the pedal down accelerating it will not shift up until I release and put it back down.(Weird)A few guys have told me it might just be the Kickdown Rod linkage on my carb.Now I have a complete manual but it does not show me what it is supposed to look like!If anyone has a 80 f150 with and edelbrock 4 barrel that could send me a photo to my e-mail,I would forever be in debt!Thanks for the help!

It could be your vacuum modulator on the side of the tranny. If that goes or the vacuum line going to it has a leak, it could mess up the shifting.

I vote vacuum leak in the line to the tranny, or at the tree were it comes from.

That's what I thought too...that is why I replaced the modulator!(and it was in working condition)But I went to see my performance specialist and he seems to think that the Kickdown rod is a little short cause the motor is from a different year*L*A small $6 fix!Thanks for the replies people...I appreciate it!
