Ok I just put in my new B&M 2400 stall when I put my motor in and the motor is runnin great but the torque convertor makes a god awful noise like the teeth in the convortor and the teeth on the bar that comes out of the front of the tranny that the converttor attacehes too arent catching and they are just grinding agaisnt each other. The car doesnt move either, it tried to a couple of times but never really went anywhere

What I need to know is so you have to let a new stall sit and run for a while before it will start to grab or what. If I reved it a couple times the car would stop making the noise like grinding but It still wouldnt move. I really want my car tonight and if I can get it I need to be back up there QUICK so plz give any replies NOW!!!!!

 

Did you follow any directions or procedure? or did you just ""slap it in there" Doesn't sound good, that's for sure.

 

Ive had a history or tranny problems so Ive put like 5 convertors on the thing, so I just did it how I always have but when It didnt work I checked the instuctions they gave and they didnt say anything that I didnt do anyway

 

Did you stab it all the way in? It has to click three times. One for the input shaft, one for the stator support, and one for the oil pump drive. Did you fill the torque converter up with fluid before you put it on? Other than that there isn't much you can do wrong on a converter install. Oh and don't try to move the vehicle at first, make sure it is full of fluid and then run it back and forth between Reverse and Manual Low a few times making sure it catches every shift, then check the fluid level again. That should give it time tyo fill the converter and everything back up.

Yea I did all that, I gave up on it for today. Ill call B&M tommorow and see what I can find out. The only thing I can think is since my car is an 86 I ordered the '84 and up 30 spline convertor, but Ive only owned it for a year. I guess its quite possible that its an 82-83 tranny that some other owner changed into it, they have only 28 splines so maybe that could be the cause.

 

it sounds like the tc is not engauged all the way
you will know its engauged all the way because you can barely stick your fingers behind it.

 

Ill check it again but Im pretty sure its engaged ,Im gonna call B&M in a few minutes, maybe they can tell me something. Right now Ive got the tc all the way up and the tranny bolted to the block. I just unbolted it from the flex plate and pushed it back as far as I could so I could at least fine tune the engine at any rate. The tc is about half an inch from the flex plate all the way back does that sound like its fully engaged?

 

The early TH700R4 or 4L60 had 27 spline 7/8" input shafts. The easy way to check is to just count the splines on the input, it is the inner shaft that you can turn, the outer shaft is the stator support, it always has 27 splines (and you can't turn it, try as you might), so don't let that throw you off. There shouldn't be much room between the torque converter and the flexplate with the transmission bolted up., definately not enought to turn the engine over with thew tranny bolted up. It sounds like you have mismatched parts.

Thats not true cause I have done it before with tc's that worked, you just shouldnt do it very long cause the vibration from the eingine will eventually make the tc slide gently forward into the spinning flexplate which isnt good

 

Wow and I thought I was a backwoods redneck! I don't think I would do that, but hey its your car. Also you really shouldn't have much room between the two with your tranny bolted up, I think somethings wrong there.

The torque converter should have .090 - .125 clearance between the flex plate and TC before you bolt it up, anymore than this starts to wear out the front pump rotor at a quicker rate. In your case a 1/2 an inch will not let the torque converter hub engage at all and if it started to engage it would wipe itself out in a matter of minutes or even seconds. This is not uncommon of B&M TC's, from what I have seen in the past. If this happened, the front pump will need to be rebuilt/fixed.

 

Before I bolted it up it did only have very little clearacnce. The onlytime I had like a half inch or so was when I unbolted it and pushed it all the way back with a little 8" pry bar so I could play with the motor without worrying about it
