4L60E For a stock 4200 its more than plenty. Before the turbo went on it got a severe upgrade. So now its more like a 4L70E.

Originally I was shifting the trans manually using 2 toggle switches. Before the snow hit in Dec. I started beta testing the megasquirt transmission controller. It ought to be available by May. No set price yet but it'll be at LOT less than the commercial units. Wild ass guess under $250.

Didn't mean to hijack the thread.
