Put the trans back in today(904) went for a test drive.Everything felt good came to a stop and took off nice and easy shifted the trans up to second and pow smoke everywhere.Totaly disgusted I locked the doors and walked home,about a half mile.My friend tony grabbed his truck and trailer and we went and hauled the cuda home.I thought that the front pump let go again,but I was wrong.Climbed under the car quick and found the torque converter is split.What would cause this to happen?I shifted the car at 2200 rpm's when it let go.the trans is a 904 with a low gearset and a manual valve body,the converter is a 2600 -2800 stall and only has about 250 miles on it.The confused and frustrated Clown

Man that's the pitts, sorry to hear, maybe tractransman will know 

[tactransman]

Man , you have to be getting frustrated.  I have never seen one crack there. What brand of converter is it? I would almost say someone did a bad build job on the converter. Other than that I would say (even though I have not seen it) that converter fluid pressures were too high. If it were a lock up , I would say that someone milled the cover too much where the clutch rides (they do that on a rebuilt L.U. converter to make sure it is flat where the clutch rides), but it is not a lock up , right?

wonder if the fluid loss th 1st time was the converter?

[moparclown]

Its not a lock up,and it was made by suncoast.Do you think this could have started with the mishap a couple of week's ago when the fan took out my radiator?could it have ballooned up when the engine hit 7 grand?and now it just split where the metal stretched?I might be reaching on this one but I am really frustrated and would like to know why this happened.And I thank you for any input on this tactransman.If it was ballooned out could that be why the other pump got waisted?----The Clown

[tactransman]

I thought that this was a new converter since the pump problem. If this converter was the one that was in the car when the pump went out then yes I agree with your theory. I wonder if they used a lock up converter cover for a core, and it was stressed from when it was a lock up. (the covers look the same between LU and NLU)

[moparclown]

Thank you sir,I will try and get the umph to pull this today.Thank god I didnt pull a 6 grand shift,I might not have any feet right now.------The Clown

[tactransman]

You might want to look into this company for another converter

Pulled the trans. out tonight.heres a better photo of the split,should I pull the trans back apart?-----the Clown

[sleepychallenger]

i would open it up just to check for metal shavings or anything that might of come loose. who knows when that happens. best of luck to you.

[tactransman]

I would not touch the transmission, by the sound of your story , I don't think you ran it low on fluid.It should be fine. Looks like poor workmanship to me. I would go with another company. I bet they used a lock up cover for a core and it was weak there. Try P.T.C. I think Chryco has one of their converters.

[moparclown]

When I heard the noise and saw the smoke I shut the ign. off and coasted into the dodge dealership. tonight I removed the drain plug and dumped the rest of the fluid into a clean bucket,and all was clean.I think that I will pull the pan off just to ease my mind.----The Clown

[sleepychallenger]

if the fluid was clean then i would say leave it sealed and get another converter. i wasnt sure if the fluid was run low for a bit or not or how the fluid looked.

[Chryco Psycho]

Chryco doesn`t & will never own an auto vehicle

Is it just me or does the converter/flexplate bolt boss look crooked like the converter is ballooned in the first picture of the converter on the bench (looking and comparing the bolt boss to the converter hub)
