I tried this before and was getting some good response and it was deleted. Ryan told me it was a technical error, so I will try again. I have a 55 Pontiac with the Hydra-matic trans, last year for this version. When i drive it hot or cold it waits too long to shift into at least 3rd and 4th. However if I let off on the throttle just a little it shifts right away. Also when it is warm, when it down shifts into 1st when coming to a stop or making a slow turn it hits so hard iit almost throws me forward! I have been told there is several adjustments but don't want to mess with it if I don't have a clue. Oh, and for you "do a search" guys, I have and there is lots of Hydra-matic info on here that never addresses this issue. Any constructive help would be great!
