i have put in and taken out 10+ trans and never had a real issue but this has be stumped.

when i get the trans mated to the engine i am unable to rotate the flywheel to put the nuts on the TC. tonight it the THIRD time i have put in and taken out the trans on my truck. and am still unable to turn the flywheel i have as far as to put the starter back in and do it that way but not even that worked. i am lost

I was told that the TC was not fully seated so i did everything i could to make sure that it was is there anything else i should make sure i do before i try this a fourth time.:cursing::cursing::cursing:

O forgot to mention that im working on a 2006 6.0 and the trans came off the same year truck that was 4x4 and going on my 2x4. If that make a difference.

The last time that I had a problem like that it turned out that I had forgotten to take the pilot busing out of my crate motor's crank. Therefore, I would measure the OD of the converter snout and the ID of the crank center. It sounds like there is an interference issue there.

The trans has to come out again.

Pull the torque converter out of the trans. Is the end damaged? If the converter wasn't fully seated in the pump and you bolted the trans to the engine you most likely mushroomed the end of the converter. I've seen someone carefully clean up the damaged end and reuse the converter. Usually it takes a new converter. You also need to open the pump and see if the gears were damaged. I have seen this happen and shatter the pump gears.

The best way to make sure the converter is all the way seated is to turn the trans on end with the bellhousing facing up. Then spin the converter until it drops four times. Once it is all the way down it will be below the surface of the bellhousing. If it isn't below the surface keep spinning. This is how the converter is seated in a transmission factory.

:whs:

I forgot all about having the converter completely seated. The measurements were to confirm that the snout is the right OD and/or not mushroomed as previously suggested.

I've never seen the snout of the converter (the end that goes into the crankshaft) mushroomed. I have seen many where the end that goes into the pump mushroomed.

Is that with the transmission, or just the flywheel and torque converter? If you got the entire trans for that cost, that's awesome.
