By saying that I cannot drive fast enough I mean I cannot drive more than - I think - 30 MPH for the first 10-15 minutes. Too dangerous for the highway and I think bad for the engine because it makes a lot of noise due to the high RPM.
That the oil pump is not functioning well sounds plausible to me. I thought it could be the oil (too cold) that is why I put the gear into D (to warm up the oil faster), but if ithe oil pump is the problem that may not help. RUnning the engine for 10-15 minutes will do then.
The problem occurs when the car has not run for hours.
We have some weddings to drive this summer but I think we will buy an rebuild kit for the transmission and rebuild the transmission in winter.
Are these good ones?

We have got the 1956 De Soto service manual. Is there a good service manual for the Powerflite transmission?
Thank you for helping!!
