Pump splines chewed up
Pump splines chewed up Been having issues with car luanching and flashing convertor. Was told by a few people I could have an issue with the pump spreading and bleeding pressure at wot. Pulled trans out and pulled out convertor and found this.
One off my trans is on the left and the end of the splines are all chewed up.
Convertor looks fine inside. There not a bunch of metal in my fluid either. Kinda at a loss. I dont wanna send convertor back and have it cut apart if I dont really need to. But I dont know what could have caused this beside something in the convertor.

From everything I can tell theres nothing in front of the stator, which is what those splines go into in the convertor, that could have done that. I can reach in the convertor and spin the stator and it spins nice and freely.
I should be the stock one that came in my car as far as I know. But the trans has been apart several times. My tranny builder says he has always kept my same pump cause he doesnt like to mix match parts. Ill measure it all tonite when I get home. Im thinking it could have been this way for some time and we just never noticed it. I had a convertor totally take a dump and come apart 3 years ago and it could have done this and we never saw it......IDK
It looks like it has the wrong stator tube. The right one should measure 3 7/8" from the pump surface to the end of the tube.
It looks like the stator was only engaged about 1/8" and it finally gave away and stripped out.

i have a few stators like that in my garage on factory pumps I have seen a few of those they came like that on some models kinda graduated at the bottom is the best way to describe them.

Verdad Gallardo It only measures about 3 1/2. 3 years ago when I had convertor take a dump we had to replace the pump because it was trashed. So I am thinking the pump I got was a shorter stator length then what I was supposed to have.
Just measured the inside of the converter and it measures 3 1/2 inches from the front side of the stator inside of the convertor. I have the right stator, the longer version.
What sets inside the convertor in front of the stator that could have chewed the end of that up?

I have a LS1 pump and a V6 pump. The V6 pump is close to 3 1/2", measuring off an LS1 converter that leaves around 1/4" engagement into the stator.
So that little bit of engagement couldn't hold and stripped. All that metal went somewhere, being that there is a bearing on each end of the stator and that stator support tube lost all of it's metal right in the middle of the two I'd be concerned about what it may have done to the bearings.

Think about it, if the tube is 3 1/2" long and the stator is 3 1/2" inside the converter, that leaves no length for it to engage.
An LS1 stator tubeis 3 7/8" off the pump as seen in the picture.
