no stall

3000 rpm stall converter not stalling on new tranny worked on old tranny but works like stock on this one could too much fluid in the tranny cause this.the thing has been used for 1 week only the old tranny burned up had it flushed no metal was in it.

No, too much fluid would not cause that problem. My guess is that you do not have the timng set correctly on the engine, therefore it is not producing the torque it used to at low rpm. Is your vacuum advance hooked up and working properly? Did you change cams?

i changed nothing with the motor the timing is the same runs good no stall even grabs at 500 rpms truck will not idle lower than that.

Man, it sounds like you have a lock-up converter that is in the on position at idle.

there is no electronics on this tranny old th350 tranny dont think it has lockup. same tranny as the last one just cant figure it out wondering if it will mess up a good tranny

Wait a minute, this is a new tranny. Gezz, I miss read your first post somehow.

Here is the deal, your frictions and steels also known as clutches are too tight or your band is not adjusted with enough clarence. I am thinking that they are dragging. What will happen if you drive it as is, they will get looser, hehehe and within a month or so, it will be just fine! Someone installed one too many clutches in the 1-3 pack.

thank you so very much he told me he put 5 clutch pack instead of the standard i guess its 4. he built it for racing so you think about a month. i need to be really nice till then right.
if not how long should you be nice to a tranny when its new. i mean before i race it down the strip.

500 klms or 300 miles is the break in period for clutches. As for how long before it will start losening up, your guess is as good as mine, but keep us informed. If you have high performance clutches it will take a little longer, but one or two hard runs, as in petal to the metal, might take care of it. We are only talkin' .005-.01 of an inch before it will work properly. I beleive the proper clarence is about .015-.02

it has kevlar lined clutches in it so i would imagine it might take a few but i thank you very much this is the first time one of my questions has been answered it feels good to get help sometimes i love to build motors, and body mods but i know nothing about trannys.

I LOOKED AT THE SCEMATICS ON THE TRANNY AND DONT UNDERSTAND THEM COMPLETLY. B&M SAYS THAT IT SOUNDS LIKE MY FORWARD AND REVERSE BANDS ARE ACTIVE AT THE SAME TIME BUT IT WORKS QUITE WELL STRONG SHIFT JUST NO STALL. YOU THINK I SHOULD JUST DRIVE IT HU?
