    Allison 2000 (July '01 Build) 4x4 conversion

    The advice in the gears magazine, is to lift the rear of the vehicle higher than the front, using gravity to keep things in place.

    Allison 2000 (July '01 Build) 4x4 conversion

    The September 2009 issue of Gears magazine shows how to repair a broke tailhousing without removing the transmission. I think the same procedure could be used to convert the 2000 to a 1000, and as Rockabilly said, the planetary also needs to be changed. The hole for the output shaft, through the...

    Allison 2000 (July '01 Build) 4x4 conversion

    @THEFERMANATOR Thanks fore the additional information. I didn't figure the J1939 would be plug and play to a GM TCM. I was thinking more along the lines of a MD TCM, re-tuned for pickup quality shifting. I was going to contact Jason over at transmissiontunerdotcom. His web site claims he can...

    Allison 2000 (July '01 Build) 4x4 conversion

    @THEFERMANATOR @Rockabillyrat Thanks to you both for taking the time to respond. I have experience with automatic rebuilds, but none specific to the Allison. Mostly I've worked on 4L80e's, 4L60E's, 4T60's and such. So I am confident in automatic rebuilding, just not the Allison. The intent is to...

    Allison 2000 (July '01 Build) 4x4 conversion

    @THEFERMANATOR, and others. I am looking deeper into this conversion. I would like some input on what is needed to get the 5 speed to confidently handle a 300-350RWHP 24v cummins. So far I am thinking upgraded c1/c2's (reybestos torqkit) and a Trango JR. I know the full trasgo is better, but I...

    Allison 2000 (July '01 Build) 4x4 conversion

    Thanks for affirming my suspicions about the valve body. I did some fitment checks with the sae 3 clutch housing today. This is a 2nd gen Cummins. The Allison won't be going in yet, the 47re will be going back in for now. I bought it with the converter bolts all backed out. The seller thought...

    Allison 2000 (July '01 Build) 4x4 conversion

    I managed to score the parts I need for the c5, p3, extensions housing and output...vitually another complete trans. It’s a 2001 basket case that seems to have everything with it. Guy said it was cooked, but minus slight discoloring of the plates, it doesn’t look bad at all. That’s the good...

    Allison 2000 (July '01 Build) 4x4 conversion

    You guys are great, and I love the friendliness of this forum compared to others. I have a line on the P3, C5, extension housing, and park Pawl parts. If everything goes well, I should be picking them up after work tomorrow. I have an early style TCM with the red/gray 32 pin connectors. the...

    Allison 2000 (July '01 Build) 4x4 conversion

    That's good information about the 4x4 Kodiak's Fermanator. I remember reading they had divorced t-cases....NV273's, I think

    Allison 2000 (July '01 Build) 4x4 conversion

    Thanks for the replies, I will have to swap out to the 1000 p3 planet then. I do not want to go with a divorced t-case. Rockbillyrat, out of curiosity, what is it about the 2000 p3 planet that the 1000 4x4 shaft wont work, is it the size and or spline count cut into the P3 different between the...

    Allison 2000 (July '01 Build) 4x4 conversion

    Can anyone give me the parts list or point me in the direction to find a parts list to convert an Allison 2000 to 4x4 with a park pawl, while retaining the low ratio (wide ratio) the 2000 offers if possible. I know I will need a 4x4 extension housing, output shaft, c5 piston. I just don't know...
