Re: IML: 1960 torqueflite question

Robert,
   This could be clogged lines, OR the lines could be smashed. 
Look at the VERY closely.  I had a 75 Plymouth Custom Suburban
Fury Station Wagon with a 400 and 727 that showed this and it was
a combination of that AND a VERY SMALL PART (3 inches) of the
line had been replaced with VERY small diameter copper tubing and
it became blocked and restricted the flow and caused the tranny
to over heat in high demand peaks (like very long drives across a
large city - Houston).  Look very carefully, or better yet, to be
safe, replace it if you have not already done so.
