Help: Input shaft blocking torque converter from seating

Hey guys,

Bought a 2007 3.6L with a busted engine (timing chain). After tearing it down, rebuilding the head and swapping out all timing components, I've been beating my head against the wall (don't worry, no literally..) trying to figure out why I can't get the torque converter seated all the way back into the trans.

It came out when I originally pulled the engine. After several hours across two days of trying to get it fully seated, I got the bright idea to measure the clearances and realized that the input shaft is about 1/2" too far out of the trans. Somehow it must've pulled out a little when removing the engine.

Has anybody encountered this when trying to reinstall an engine? If so, how did you get the input shaft all the way back in? I can turn it, and it still seems to be engaged. Also there is no end play on the shaft; doesn't feel like it's coming out and I wouldn't have suspected it did if I didn't measure the clearance inside the torque converter.

Thanks!

Believe the input driveshaft protrudes past the lock up torque converter toward the block. At least for the 6 speed 09D transmission. Probably why there is no play. Not certain how far back in the bell housing the converter should seat. Look at the transmission section drawing on page 21 of "The Touareg" self study guide 89E303. Should be able to find a . PDF file on line. Sorry could be no more help.

I don't have touareg specific info but I believe a fairly generic installation challenge with most if not all auto trannies is not seating the torque plate and or torque converter properly.
