    Aisin Trans To G56?

    Hey all, so what I’m doing is swapping my 2013 Aisin for a G56 manual.

    Has anyone on here done it?

    Has some info or pointers?

    I will keep it posted on how it goes.

    I’m gathering parts now.

    I know so far I’m going to need front and rear driveshafts modified.

    My T-case will work G56 trans, and the adapter plate revised tunes to manual truck pedals, of course.

    My truck is a Longhorn, so I will have to modify the center console and some wiring for the neutral safety switch and reverse lights.

    Re: Aisin Trans To G56?

    I have been researching this swap for about 2 months now, as I will be doing a 68RFE to G56 or NV5600 Swap myself. Here are the parts I have gathered/borrowed from the internet:

    G56 SWAP
    -G56 trans used, reman, donor truck, etc.
    -clutch of your choice, steer clear of stock. Mine came with hydros, fork, release bearing.
    -bellhousing adapter cummins #3999928 Can use the same as the 68RFE
    -manual trans file from your tuner or dealer.
    -7 qts of fluid for G56 of your choice.

    "CLUTCH PEDAL ASSEMBLY"
    (You do not need a new column. Just pin the clutch pedal in.
    - clutch pedal w/pad: 52009944ac x1
    -bushing: 52010309ab x4
    -pedal pivot shaft: 52010318aa x1
    -shaft snap ring: 6023879 x2
    -pin for master to pedal: 52010331ac x1
    -clip for above pin: 4581512aa x1

    "FLOOR CONSOLE"
    (Main console is 2 pieces, front and rear.)
    -rear piece: 1eb18dx9ab x1
    -front piece: 1eb16dx9aa x1
    -bin insert (elec. Shift tcase) : 5gt27dx9ab x1
    -cup holder matt: 1eb17dx9ab x2

    "SHIFTER ASSEMBLY"
    (There are 4 boots including the one on top of the shift tower.)
    -boot: 5161544aa x1
    -boot: 68069869aa x1
    -boot: 55398764aa x1
    -boot: 55366042ab x1
    -shift lever: 68189341aa x1
    -nuts for shift lever: 6104716aa x2
    -knob: 52104174 x1
    -nut for knob: 6502556 x1
    -knob insert (top piece labeling shift pattern): 55366060 x1

    "TRANSMISSION SUPPORT BRACKET"
    (68RFE crossmember is the same.)
    -support bracket: 52122334ac x1

    NV5600 SWAP
    NV5600 transmission
    NV5600 shifter
    Lower rubber shifter boot
    Upper shifter boot
    Uinta stainless shifter knob (optional)
    NV transmission mount
    NV transmission bracket (goes between mount and transmission)
    Southbend dual disc 3250lb for a 2004 dodge (flywheel to clutch fork)
    Southbend .750 hydraulics (slave and master)
    Volair .580 crank spacer
    2004 crossmember that was NV equipped.
    Rear driveshaft had to be shortened 4.250"
    Front driveshaft had to be lengthened 4.250"
    Clutch pedal out of a 2003-2009, they are all the same even the 1/2 tons
    Clutch pedal pin and e-clips
    Master cylinder plastic pin

    The reason you have to use the Volair .580 crank spacer is because it spaces out the flywheel so the input shaft goes into both discs and spaces out the ring gear perfectly for the starter.

    This is ONLY if you use a standard NV flywheel in conjunction with the G56/68RFE flywheel housing (they are the same).

    Now mny truck is a Larame and I have the center console as well.

    There is a way to modify your console to have the shifter and retain the console.

    Please see Pic:

    Hope this helps!

    Starting this process myself (still in the parts-gathering phase).

    Found a series of YouTube videos by ChoppyThrottle that describe the conversion in good detail.

    A few things are missing (torque specs, reverse light wiring), but overall it's an excellent series to watch.

    It also has part numbers to use.

    Re: Aisin Trans To G56?

    Which route did you go?

    G56 or nv5600?

    I have a 4th Gen 6.7L that currently has the 68RFE in it, and I want to swap it manual.

    I loved the NV5600 in my 2nd Gen, so I was wanting to go that route.

    I just purchased a G56.

    I have a 4th Gen/68RFE.

    NV5600 swap is a little more detailed with driveshaft resizing and transmission support bracket. G56 is, in my opinion, a more friendly swap.

    I got my MM3 from DRD today, and I got the manual program file from MM3 yesterday.

    So I will keep everyone updated.
