There is a TSB
about defective d-ring seals
being used by the factory after a supplier switch
in 46RH and 47RH automatics,
starting in late 1993
and corrected in late 1997
if I remember correctly.

I think the 46RH was basically a good design,
but the defective seals caused problems.

When the 46RE came in 1996
along with the OBD-II PCM system,
I believe the new VFS caused a lot of problems by simply failing,
and further problems by reducing the ATF fluid flows in a
'penny-wise, pound-stupid'
attempt by Chrysler to improve MPG slightly.

The SAE paper # 982674 by Chrysler
{see attachment}
does show in the graphs where they compare four different ATFs
that the Chrysler ATF+4 (9602) fluid had less friction clamping ability than the ATF+3.

I know that soon after I switched to ATF+4 in a 1995 46RH,
I was initially happy that there was less 'bump shift' when coasting to a stop as the trans downshifted into 1 st gear,
but my torque converter lockup clutch began to slip.
