Allison in with some mods. A call to Destroked gave us a few important mods to the Allison. We had to grind off the bumps at 9 and 3 inside the bell housing. It fit like a champ after that. I put the new short bed fuel tank in. I also dressed out the new rear axle; complete with...- BombDocDiesel

Allison fun The Allison in…..coming back right back out!! Well, the converter just clears the hub on the Destroked flex plate. In fact there is no clearance once you have the bellhousing bolted. It will be coming out again after I go to the shop for driveshaft fitting. I made a mount...- BombDocDiesel

Motor's back in Colt Cam, 110# valve springs, and pushrods all in. 110HP DDP injectors in. Studs in. Mumau came through today with the rest of the gaskets and seals I needed. I still need to get a bolt for the Destroked plate since it needs to be 10mm with a 12mm head! I also need to...- BombDocDiesel

I ended up using wax/grease solvent. It's actually the same composition as lighter fluid; just wipe it on and let it sit for a few, then wipe it off. That wax kicked my butt for two days.- BombDocDiesel

Allison 5sp: Trans Temp Gauge Installation in Chum
Ben, I have to wire one wire into port 2 on the OBDII connector. I read through my Chilton, which may just not show the circuit, but I can't find for my truck to be pre-wired for it. Hell, if it was it probably got taken out with the Cummins swap since the 4L80 came out in favor of the NV4500...- BombDocDiesel

Allison 5sp: Trans Temp Gauge Installation in Chum
I was going to try that but the TCM is a stand-alone. I assume the factory sensor is somewhere in the system I just need to figure where that is and try to make it work.- BombDocDiesel

Allison 5sp: Trans Temp Gauge Installation in Chum
Where would be the best location to tap for Trans Temp? I do not have the HD gauge cluster. Since I am certain I can't just swap in the cluster I need to know where someone would recommend. I was considering the pressure tap next to the spin-on filter but I am concerned about the pressure...- BombDocDiesel

Trac bars! (I hope) Those DuraGrapplers I bought are 11" wide and softer compound. We will see how it handles 550HP.- BombDocDiesel

Rolling Chassis Today It doesn’t look like much. The spring hangers will be welded tomorrow. The measurements take forever. I’m pretty sure at this point the frame is probably closer to true than it was from the factory. I spent a lot of today pulling rear brakes from the new axle. I...- BombDocDiesel

Cab ready to come off I got everything ready today. I will have the cab in the air in the morning. Hopefully, the motor will be out tomorrow as well so I can replace the oil pan and pump. GM ECM and harness. Yeah, it goes back in.- BombDocDiesel

One piece driveshaft question
Cool. I was concerned with the lack of a slip yoke. I will make sure the guy at the shop here is still willing to do it. I was really not looking forward to buying a factory RC/LB two-piece to have it cut-down.- BombDocDiesel

One piece driveshaft question
I have a shop here that can make one. The truck was RC/LB with a one piece but the NV4500 had a slip yoke.- BombDocDiesel

One piece driveshaft question
Is it possible to run a one piece driveshaft behind a 2wd Allison? My truck is a 2500 cut to a RC/SB. Would anyone advise doing this? I'm trying to avoid putting a carrier bearing back in the truck now that is shorter and lowered my angles work out well without it.- BombDocDiesel

Allison Rebuild Main Shaft not seating
I am almost finished with the rebuild on the Allison. I tracked down all of the balance pistons, bearings, bushings, seals and a new C5 from TKT Sales out of PA. The kit is a Stage 4 from PPE. The pump came from a new pull-out '09 Allison. I am including most of the build up pictures. I...- BombDocDiesel
