    Roasted Allison

    Taking a 5spd apart for an acquaintance of mine to do a small budget build. Truck still drove and shifted, just wouldn't hold any power. Turned out to be pretty bad. Trying to source a new gear set, but he thinks he found a usable core trans instead. Trans looks to have not been apart, at least...

    Pacemakers Dragway 7-21-23

    We had a company night at the track, employees and family only. Made 5 passes in the truck, two best were 8.002 and 8.046. Not terrible for an all stock motor and turbo I guess. And I think I'm at the limits of what this 1056 converter will do, tried to launch it harder on one pass at about...

    LLY FICM

    I suppose this could be a wtb thread, but am looking to see if anyone has a good FICM that I could borrow? And we can discuss testing if you guys would like... So some of you might have read that my truck quit on me a while ago. With watching the kids, holiday season and helping on the tree...

    Buddies truck, 2013 Chevy 2500 6.0L He's been having some trouble with O2 codes, knock sensor faults and something else. I haven't had time to personally diagnose it, but trying to give him direction. He took it somewhere and they told him bad ECM (myself and another tech don't agree, but...

    Converter change / rebuild

    Just looking for anyone who has had a Suncoast converter changed or rebuilt, some insight maybe? This 1056 is getting some miles on it, and I will admit wasn't brand new when I put it in circa 2011. I called Goerend because I hear fantastic things, but Dave (I think) was kind of wishy washy...

    Burnt up Kennedy pump

    First, I can't complain too much. Pumps have been on the truck since 2010. So a short story long, I rebuilt the filter head due to a start / die condition. Decided to check pressure while I was at it, only 2psi. Well wtf, checked voltage back by the pump plug and had 5-6v, wire was corroded...

    Allison 5sp: Cooler debris

    There are a couple pictures attached. Trans started running hotter than usual (210ish even when cooler outside), so Friday night I drove the truck around to get temp in the trans/engine and backflushed the cooler lines with compressed air. Only got about a qt into my catch bottle, had a...

    Help: 05 GMC tccm

    Having trouble getting my truck in/out of 4wd after the conversion using Ben's harness. I emailed him and he gave me a couple things to check, and replied but you know how that goes. Basically I'm looking for a known good TCCM, gm part# 12590219 to rule this out as the issue. I have a...

    Allison 5sp: 2nd gear starts

    I decided to mess with the tcm tune a little tonight, more or less to play with the TCC tables since the slip limits are available now. Anyhow, I tried to make a 2nd gear start tune, for normal driving modes since 1st gear is so short. I changed the 1-2 upshift tables, 1-2 WOT , 2-1, 2-1 WOT...
