    To keep the weight of the transfer case from breaking the transmission's case.

    They don't put them on cars because car's don't have transfer cases.

    are you talking the 2 braces going from the motor mount to the inspection cover on the tranny, or the 1 brace from the t case to the bellhousing bolt?

    i have neither and haven't had a problem, yet /forums/images/graemlins/crazy.gif

    thanks, but wouldn't you think the tranfercase mount would sufice. for the average HP of a stock engine?

    I doubt GM would put them there if they didn't need to be there.

    The way I see it is that the Engineer who felt they were needed had a good enough argument for them that he (or she) was able to get them past the Bean Counters. That means they're important.

    [edit] If you're going to leave them off, you first need to figure out why they are there. Then you can make a valid decision about whether your use needs them or not.[/edit]

    I've seen many trucks without them,but they never leave the pavement--take one off road and flex it good,or get a little air,and the tranny bell will crack--it is nessasary--I have similar "rods"on my diesel that go under the motor mount pads to the inspection cover under the flywheel--but somebody put a 2wd case TH400 in it evidently,because it has a tin cover instead of the cast aluminum one,and there is no place to bolt the rods too.I hope my tranny doesnt crack,but I dont go off road or get it airborne very often,and the NP208 isnt as heavy as a NP205 is,so it should live.
    I noticed on the 305 motor I took from an 86 van for my 79 C10 had a triangular shaped steel plate between the block and the drivers side motor mount plate--anyone know what the hell they put only 1 of them on for,and what it does?--I left it off,never had seen one used before--maybe its a "van only"deal?? Its got me baffled! /forums/images/graemlins/dunno.gif /forums/images/graemlins/dunno.gif

    I used to manage a transmission shop. Every truck I saw without them that was used offroad ended up with a busted transmission case, or had problems related to flex in that area.

    It MIGHT not be so bad with the aluminum transfer cases.

    My truck has both of those braces, the one that runs from the side of the transfer case to the bellhousing, and it also hase the mount on the side of the transfer case that goes to the frame.

    i had the brace that hold up the t case on mine. couldnt get it off so i cut it between the two bolts on the t case. it fell. wasnt even attatched. i wonder if im missing any bolts up there. the tranny was just rebuilt 2 years ago. dont think im going to refer that place to anybody.

    i understand the theory of "GM put them there, you should keep them there"

    however

    explain why a sm465/NP205 does not have such bracing? its a much heavier combo.

    some 205s did have torque mount that attached the tcase to the frame, but not all.

    Easy, thicker b/h and cast iron trans case. Not the same at all.

    Sounds like one of the mounts for the support bars on a 4wd. They sandwich between the motor mount and block. I bet they took the engine out of a 4wd and left it on there.

    No,it is the original van motor(codes match the van's VIN !)--the triangle thing is simply a shim I guess,about a i/4 inch thick--there is no place to attach any rods or other bracketry to it--I guess the vans need it for some reason--unless I run into the guy who designed the van,I'll probably never know!.I left it off when I put the motor in my 2wd pickup,since I never saw one before in ANY GM vehicle. /forums/images/graemlins/confused.gif /forums/images/graemlins/dunno.gif

    Tim is 100% correct, you DO need 'em! I misplaced the ones on my '80 Blazer, whe I changed the engine in it, and busted the crud out of the tranny 2 weeks later.... /forums/images/graemlins/eek.gif /forums/images/graemlins/eek.gif /forums/images/graemlins/eek.gif

    Anybody know where I can get a set of these braces. The set I have is F'd. Looks homemade to begin with. I'm not even sure how they are supposed to be in the original configuration. Anybody got a picture.
