    Mike, I have a question about the 2010-later 6 speeds...

    I know the VB is different, but my question is whether the main case, front housing,rear housing, and guts are any different. Mainly, can the front housing from an earlier 6 speed (such as the SAE 3 housing) be transplanted onto the 2010-up transmissions? Also, will the 2010-later variable...

    TC to flexplate spacing

    Awright, so I'm getting the Ally fitted to the back of the Cummins using a Dodge-to-SAE #3 adapter (keeps stuff much shorter than the OE Cummins SAE #3 housing). My question is spacing: On a typical DMax install, if the converter is fully seated into the pump, what is the spacing between the...

    Do 09's still suffer from pump rub-through?

    Friend of mine got an 09. Just checking to see if they had fixed the issue at this point, or do the t-cases still need the pump rub kit?

    Allison 6sp: TCC and shifting

    I looked around a bit and was unable to find an unequivocal answer to a couple related questions: Why does GM have the converter unlock during shifts, and aside from possibly harsher shifts is there any downside to disabling this so the converter stays locked? The reason I ask is that it seems...

    Allison 6sp: Flexplate tech

    This isn't on a Dmax, but it IS for an Allison. It seems that all of the billet flexplates I have seen, whether for a DMax, Cummins, or Stroke, are quite thick. Some looked to be 1/4" thick from what I could see. Now, flexplates should "flex" somewhat to take up minor misalignment between the...

    C3 backing plate mods (mainly for Mike's input)

    Ok, since I have acquired an extra C3 backing plate with the parts trans I got, I started measuring stuff and tinkering - I can never leave shit alone (anyone else have this problem?). Since only 4 C3 frictions sucks (or does it?), I looked into modding the C3 backing plate to accept 6 full...

    Houston, we have a problem - Mike, I need your analysis!

    I mentioned in another thread that I got what was supposed to be a 2007 Allison with 21K miles on it. Well, I still think it has only 21k miles on it, but when I pulled the output shaft I found the P3 planetary was junk. So, I began tearing into the trans and found a lot more issues. Now, this...

    Allison tech info

    Hello all, I am doing a standalone swap and I scored a 2007 6 speed Allison from a wadded up DMax truck with 21k miles on it to use behind my fairly tame 12V Cummins. I have an 01 5 speed TCM and wiring harness, matching NSBU (2 plug jobbie to match the harness), and I will be using an SAE #3...
