My 6.2 was toast so I decided to put a big block in it but i wanted decent fuel mileage so I changed my mind and went with a 5.3 with a 4l80 and a Np241 t case. I installed a ord cross memeber, new an lines for fuel and transmission lines. I had a local guy build me a harness and it included e fans provisions.Please tell us the details.
Replace the bearing and the tail shaft housing seal then reassembled, then my Crank trigger sensor went out and the truck would not start. Replaced that and the truck started. Hopefully this week, the fuel pump (the current pump is only pushing 45 psi, I need 60 to run). if all that falls in line and the truck runs as it should ill start on a few small things the swap needs: VSS pulse emitter on the transfer case, torque converter lockup switch, GM knock sensors, and shift solenoid on the 4l80 then onto brakes and interior and maybe driveable by October or sooner. I do need to install my Efans and wire them up also but that can wait till it's driveable.If you are that far in to it, it couldn’t hurt to replace the bearing.
