LS1 / 4L60e cuts power in 1st and 2nd under load Putting this out there in case somebody runs across this in another swap because it was a little frustrating to find.
Background:
04 GTO drivetrain was swapped into a 69 Camaro convertible.
Car drove like a champ under light throttle in all gears.
Ran like a top in 3rd and 4th gear.
Sudden load in 1st or 2nd gear would cause it to sound like somebody just stuck a rag in the exhaust and power was WAY down.
Ended up being a brake switch that was somehow engaging under load.
