I can't tell you about the manual trannies. The auto is the new electronic
multispeed. [Give me a Dave Smith built Pro Trans A999 with low first
gear, titanium drum, 5.0 lever, and full manual reverse valve body.] The
verdict is still out on the new mopar slushbox. My general first
impression is that it is a piece of crap. PLEASE SOMEBODY BUILD A SHIFT
REPROGRAMMING KIT OR TELL ME WHO CAN REWORK THIS THING!!! It shifts like a
'78 Sedan de Ville.
4.7's have the old 9 1/4 differential, first used on '67 Behemoth's with
440's and 4 speeds. The 9 1/4 is SUBSTANTIALLY heavier than the 8 1/4
unit. That extra weight has to be turned and will increase the drivetrain
loss.
