Okay since this was the most active H-body forum I could find I figured id see if you guys could answer some questions.
So hear me out, I have a 1996 Park avenue Ultra. It has the series II 3800 supercharged v6, What im trying to find out is if
this one year only run had the 4t65eHD or the slightly older 4t60e. I can't seem to find a good answer anywhere.
My first car was a 90 Bonneville. 2nd was a 2000 Grand Prix GTP. I rebuilt and modified both.
Im also not seeing any tuning options from zzp or intense. They only list 97+ anybody know why?
The sticky does not show any info on the HD trans in 96 cars

4t65e started in 97. The 4t60eHd would be in a 96 Ultra.
Call ZZP and ask them.
