1952 Hydramatic jumpy shifting


Took the Chieftain to Olds, Ab, A&W Cruise for the Cure night.  First road trip in over 30 years, she ran fine at 55 mph all the way there and back.  Whew!  Over the past coupla' days, have had her up and about around town, but shifting is very unpredictable.  I recall Dad saying transmission troubles could be rectified by 'tightening the bands'.  Anybody know anything about that practice?  Rebuilt the carb a few days ago, put her in and she now starts very quickly with just a light touch on the accelerator.  Here we go!!!

Those early Hydra-Matics did not shift as smoothly as the modern ones especially if your car has the six engine!  The one I had in my 48 Pontiac eight was even quite harsh during the first shift but was smoother during the last 2 shifts!  I have a Hydra-matic shop manual which shows how to set bands etc but very complicated and you needed all the special tools to work on them!  Most likely after you have driven the car for a while and put some miles on the tranny it should improve!  Have you had the trans fluid drained and replaced?  That also might help!

Thanks, Bob. I'll drain and replace the tranny fluid asap.

my hydramatic shifts fine but it does have a harsh downshift into first when your slowing down to a stop sign or light.Upshifting seems better.One thing I do notice since my driveway has a bit of a slope to it is the tranny has a whiney sound to it when I park it on the slope and go to open the garage door.Alot noisier than when parked on level ground for sure.That being said I put a lot of miles on mine this summer and other than a small leak on the garage floor it has run perfectly.If it doesn't leak its not a powerglide i'm told.

You don't have a hydramatic in your 54 it's a Powerglide.
