Or you can buy a new one and take a piece of steel pipe the right size and drive it on your replacement transmission.
Good luck.

thanks for the info

I solved the sensor gear issue, and installed the trans earlier this week. when I started it today to test drive it, it makes a loud clattering sound as it is running, it can be felt on the bellhousing. I know the converter was seated properly, I double checked this before bolting the trans up. What could be wrong now???

Cracked flywheel?
Converter bolts tight?
Splash cover rubbing?

flywheel wasn't cracked, convertor bolts were tightened to spec. I lowered the splash cover so it was clear of the flywheel & convertor, still makes the noise.

Any chance ther starter drive or end is rubbing flywheel?

checked the starter clearances, and all was well, I just had a thought, is it possible that I might have the flywheel on backwards (wrong side facing the convertor) would that cause the problem I am having?

Not sure about that.

I would unbolt converter and slide it back and then start engine and see if it still has noise.

I unbolted the converter, fired it up,and there was no noise. I then bolted the convertor back up, and the noise was back. the number of input splines was the same,30 splines. I could feel the converter contacting the front pump tangs,so I know it's seated fully. someone told me that the starter might need shimmed, could that be the problem??

Might not hurt to try that.

I put 3 shims in, and it still makes the noise. here is a pic of the flywheel, it shows the side that I have facing the convertor:
is this right?, or does the side shown in the pic face the engine??

Yes that is right.
Does the transmission go into gear forward and reverse?

[InMyChevyVan]

I can feel it trying to go in gear, but the vibration noise gets louder,and becomes a higher pitch.

If full of fluid and will not go into gear.
It is a internal transmission problem.
Might as well pull it out and go for another transmission.
Let us know how it goes.
GOOD lUCK

Ugh. I think I will just get rid of this van, pulling the trans in a van is not exactly easy, and having to do it outside in the elements doesn't make it any easier.

Thanks for all the help!

You are welcome.
Sorry about the bad news on it.
