    LML converter wont spin after tightening bell housing

    I’m a big fan of goerend unfortunately I think that’s the converter they send with all of their 725HP builds and require that converter for warranty.

    LML converter wont spin after tightening bell housing

    No spacer behind fly wheel. Found that the stock converter seats much further then the Randy’s converter. I tried and tried to get the converter seated. After speaking with Randy’s we thing something happened in the machining process with the snout of the converter. The lugs where the converter...

    LML converter wont spin after tightening bell housing

    The white marks on the flex plate are not scratches. It’s from where I cleaned off the paint marker I used to mark the flex plate bolts as I torqued them.

    LMM P0878

    Seems to do it all the time for the most part! regardless of hot or cold. It only does it every 30-40 or so times you go to reverse from drive or neutral or park!

    Mangled glow plug removal

    I could be wrong but it seems like I remember my snap on guy promoting a special tool specifically built for broken duramax glow plugs a few months ago. I could be wrong and if I am not wrong I am not sure how it works or if it works but it might be something worth looking in to!

    LMM P0878

    Have a buddys LMM that he just bought. Had all kinds of codes being thrown and truck wouldn't move, replaced the TCM and had a it programmed and truck runs and drives now but every few times you put it into reverse it throws a P0878 code and says "range shit inhibited shift to neutral to reset"...

    Is my allison spent?

    Mike is the man with answers but you might check the round plug on the back of the trans and see if there is fluid in it!

    LMM no start after head gaskets

    Okay, I got it figured out. I'm almost to embarrassed to say what it was but let's just say 1 loose fuel line will cause it not to build rail (obviously) lol. Like I said must have just been tired and frustrated or I am an idiot. None the less, thank you for the advice and all your time! Much...

    LMM no start after head gaskets

    Primer bulb gets hard after about 4 or 5 pumps. Goes soft after cranking. I ran a line straight to metal line that goes to cp3 from a can of fresh diesel and truck still wouldn't start.

    Okay, just to update everyone! I took the truck to Josh last Tuesday and picked it up today. He Was slammed and still managed to get me worked in. For starters my warranty was 110% expired.

    Built Allison 1-2 shift flare when cold

    Mine only flares slightly when it makes the first few 1-2 and 2-3 shifts for the day or when cold. Once fluid temp is over 100* it never skips a beat. Shifts quick, firm and flawlessly! Unfortunately I have to drive it so for the first few 1-2 and 2-3 up shifts I stay easy on the throttle so it...

    Built Allison 1-2 shift flare when cold

    Unfortunately I have been slammed at the shop and haven't had a chance to call Josh. The truck gets driven maybe 5-8 miles a day so I've just been letting it sit and idle for a bit before I leave and being easy on it! Hoping things will slow down this next week and I can get it to Josh!

    Trans Build Sugestions

    IMO the ppe kit is no where near the quality of Evan @ Limitless. I would call Evan. He will be able to answer any and all questions you might have. I do know that these transmissions are WAY different then any Dodge trans you will have built in the past. I'm not saying you aren't capable and...
