There is a break-in procedure for the band in there, from what I'm told, and if the old band is in good shape, you may want to use it. I'm just passing on what a trans guy told me. If you do the re-build yourself, get a video on the re-build, as well as a manual. The Monster trans kit looks like a good one, with heavy duty parts etc.

I recommend getting a tool to install and remove the pump, as if you install or remove it wrong, might as well just buy another trans. Also there is a piston in the very bottom of the case that needs to be removed and new seals installed, I recommended finding the tool to remove and install it, as its easy to bend and then you have to buy another.
Im not sure about rebuilding it as for strength, I just did a stock rebuild on a few of them and did a few mods as stated in the rebuild manual.

Now a turbo 400, I can pretty much tell everything that needs to be modded in it for strength.

pila wrote:I see that "Monster" has three stages of rebuilt 700R4's, like 1,2, & 3. You might call them and ask what comparable stage you will have with the kit you listed in the link. How much power are you gonna have on that trans ? I see level 2 is 500 HP, and not likely you would need any more beef than that, but knowing how the kit matches up to their re-builds would be good to know.

How bad does it surge when in gear? That's the real question.

pila wrote:Kinda strange how some of these engine will idle slow. The 408 SB in my Malibu has a Comp 280 M cam in it with Rhoads lifters, and if I back out the idle speed screw, it will sit at 350 RPM in neutral. With the slowest lope I ever heard! Weird! I suppose the leak-down in those lifters kill-off the lift and duration enough to make a tractor engine envious!
