Unhappy TH350 Trans Slipping when warm

I have a 64 Malibu with a TH350. Bought the car 6 months ago and it was supposed to have a fresh built transmission in it. Here are the problems I am having.

- When cold there is a slight hesitation when shifting into reverse but once in reverse it works fine.

- It shift fine through 1st-3rd once out on the road. Nice firm shifts due to the shift kit.

- Once the car is warm, when I come to a stop and start up again there is a slight bump like its slipping into first.

- Once warm it will slip sometimes going into third.

- Once warm it will barely shift into reverse and it hardly moves (slips) the RPM's are really high in order to make the car move.

- I have checked the fluid level and that checks out fine.

- The shifting linkage seems to be adjusted okay

I have no clue what the problem is?? Could it be a torque converter??

Any help or suggestions would be great.

not the converter.

trouble with reverse and 3rd gear points to the direct clutch drum. worn sealing rings, cut lip seals if the tranny was recently built.

Hard seals if the tranny was not recently built.
Dont worry how old you are... it is the mileage on your body that adds up.
