A518 Flex Plate Help???

Up thru 96 I think Joe.
97 and newer A518s (actually a 46RE) have a symetrical pattern.

What year did you get your Trans from? (crossed fingers)
The 46RE requires the computer to control shifting.
I hope you have also considerd the balance difference from the LA motor and the Magnum.

Well, it only has the one 3 wire plug coming from the trans, so that would mean it's a 46rh non computer controlled right?? I am not sure what year the trans is from, but does it make a difference, if its indeed a 46rh?
