Putting A 6.0/4L80E In A GMT800… WILL IT RUN?

Yes, it is time to get Phantasm running again with a high output 6.0 instead of the hit and miss 4.8. Joining the swap, a 4L80E also makes its way into the frame rails of what use to be a rotted pickup truck. The process of swapping a 6.0 in a GMT800 isn’t too hard, the 4L80E required some changes. Changing the flex plate, crossmember, wiring, and cooler lines will be required. Quite a few problems arose with the cooling system not being able to hold coolant, to getting the transmission cooler and cooler lines to fit and function as designed. This is a huge step forward to getting this truck back on the road, but the road is longer than expected Thank you for watching, subscribe today!
