when I hit the floor speed goes to 55 and stays, it does not shift in third gear, have to lift my foot a little than it works.
any ideas ?

 

This happened with my car, but going from 2nd to 3rd. I thought it was a vacuum problem, but all I did was readjust the TV cable and now it shifts fine.

my bird used to do that, but only when my tranny fluid was real low, (i've got a leak.) also, my car never shifted at 55mph into 3rd, it was always around 70-75mph. So, you just might need to adjust that tv cable. tell us how it works

 

thanks guys, but how do I adjust the TV cable, i can't find anything to adjust with, I mean no screws or so and there are 3 cables at the throttle, 2 are plastic covered
and 1 is a steel wire.
also I have to say is that I have new headgaskets and heads are magnufluxed, also a new distributercap. Could it be a timing problem? and is 10° over 0°o.k.?(auto tranny)
thanks for your ideas

 

I adjusted the TV-cable, shifting is o.k. now.
Thanks

 

At least you car will shift my car once t ges to shift into 3rd it revs up and redlines i fryed my clutches.
