I didn't forget about you! Lol just working all night and using tapatalk I didn't realize who you were. What all has to be done to do a 4l80 swap? I just thought it would be Easier to build a 4l60. Your boat can't be that heavy?
Same here bro... First night of graveyard is killer! Well other than tranny and torque converter - 4l80 to NP243 adapter, NP243 32 spline input shaft, move cross member back, new dust cover and inspection plate, possibly shorten rear drive-shaft, some repining on the harness, and reprogram. And yea it's pretty darn heavy. Boat + 35s + long trips = death
That truck, those tires, and a 19 foot fiberglass speed boat?
80 all the way.....
Yeah that's what it's looking like man... Stress killed it from the wheels/tires and hauling my boat combination. It's been built before with all the goodies, shift kit, beast sunshell, vette servo, etc. I have a trans temp gauge which I keep very close eye on, and always tow in 3rd.... Still killed it.. Trans temp was 120 when it crooked. I think it's just too much strain on it. I know I could build another 60 or 2 much cheaper than the swap but I'm ready for some peace of mind.
