    Unhappy Engine 3.8 removal or how to swap 3.8 to 3.3

    Hi

    As my engine died, I need to repleace it.
    Do you have any suggestions how to do it?
    I've read FSM, but I would like to learn more from you. Maybe some one did this on forum - photos are welcome.

    Please advise could it be done without special tools at my home?

    It can be done, just keep in mind you will need a lift. It's easier to drop it out the bottom (the way it was factory installed), however, it will come out the top. There are threads showing swapping of trannys, similar task, just lots heavier. Do a SEARCH.

    In addition to needing the engine hoist to lift it out, you will also need to get a PCM made for the 3.3 engine. Unless a 3.8 is hard to find, I would get that because the 3.3 will be lacking torque for the AWD drivetrain if you really need to speed up.

    3.8 is very rare on the second hand market .
    I don't need tons of torque and horse power - it's family VAN for me, wife and kids.

    I heard from couple guys in Poland that 3.8 PCM will work just fine with 3.3 engine.

    I've done it on my previous van ( search here, 96 T&C). The toughest part was getting the crankshaft pulley to clear the body while clearing the transaxle at the same time - I was doing it myself. As andyg said, you'll need a hoist to get it out.

    they made some grand caravan sport with the 3.3L and AWD
    if you swap the engine for a 3.3 you will also need the transfer gears in the transmission they are not the same for 3.3 and 3.8
    swapping the computer should be a 5 minute job, as far as I know they used the same harness pinout

    Don't mess with the gearing in the trans. The trans and all assoiciated gearing are matched fine.

    transfer gears are 2 gears on the side of the transmission
    they are matched together as a set
    chrysler used 3 sets in the late model a604/41te

    first set is the "stratus" set used with the stratus/cirrus/breeze cloud cars of the 90's that came with the rare 132Hp 2.0L SOHC engine common to the Neon mostly found in entry level Breeze I don't even think a Cirrus was made with the 2.0L
    they have the 50/46 ratio

    second set was used in every other version of the A604 (2.0L I4 Neon and Avenger Sebring, 2.4 I4, 2.5 V6 mitsu 24 valves 3.0L V6 mitsu 12 valves, 2.7 V6 chrysler,3.3L V6 Chrysler ) so pretty much everything EXCEPT the 3.8L !
    they have the 49/47 ratio

    third set was found only in A604/41TE matched with 3.8L V6
    they have the 46/50 ratio

    if the poster do a swap from 3.8 down to 3.3 the engine will be seriously missmatched with the 3.8l geared transmission

    and swapping transfer gear is quite common , any serious chrysler enthusiasts who likes to mod a A604 equipped vehicule do the stratus gear swap
    and I'm seriously considering doing the 3.3L transfer gear swap into my 3.8L

    I don't think it will be worth it. I have the 3.3 ratio on my 3.8 and it's not really noticeable. The 2.7 gears may be nice, but the little change between 3.3 and 3.8 will be insignificant.

    I'm thinking to get it out from the bottom (engine with tranny down, body up)
