I have a turbo 350 behind a 350 4bolt main in my 65 Imapala. It shifts into first and second OK but it will only go into 3rd after I let my foot off of the pedal, (high speed idle) As soon as I put my foot on the pedal, it will go back into 2nd. Fluid is good, just changed filter, and adjusted the modulator. Also, it will shift fine when cold (early mornings), but back to the same old thing when it is warm. Can anyone help.

Cool

Have you checked the vacuum source at the modulator? Use a vacuum guage.

The reading should be in the area of 15 inches of vacuum at idle and jump towards zero when the throttle is stabbed. Full , direct manifold vacuum is needed.

IF the vaccum is good & you replaced the modualtor , then it sounds like the 3rd gear clutch pack is going bad and will not hold power.

usually if 3rd is bad, reverse acts up too. Reverse does have higher pressure and will hold a bit better if the clutch pack is weak.

have you tried adjusting the kick down rod or tvi and have you completely unhooked it to see if it will stay in that way?
If it's a cable it could be stuck or fraid.

I will try and find someone that has a pressure guage. Thanks for the help. The thing worked great this morning, but it was 30 degrees out, as soon as it warmed up, back to the same ol thing
