How much HP does a 4L80E use
I'm guessing, so please confirm.
The approximate guideline is that a manual trans car loses 10% of the HP in the drivetrain, while an automatic trans car loses 20% of the HP with a non-locking converter. I'm guessing a loss of 15% with a locking converter.
Remember that only triple-disk converters can reliably be locked at WOT.
