Incorrect torque converter positioning damaged Tiptronic

[Xcellr8]

Live and learn. So, awhile ago I was working my through a tip transmission swap for the first time. Had a few problems getting the torque converter to bolt up to the flexplate. Eventually got it all bolted up and put back together, only to discover that during testing after swap that I had no action from the tranny. 99% sure now that the problem all along was incorrect installation of the torque converter into (onto) the transmission.

Yes, I had it pinned, or so I thought, but having now removed that substitute tranny and swapped in yet another, have discovered that on the first sub I had to force the pin in and that all the force was really doing was putting the torque converter at an angle so the pin would go in. And, now I know, even doing that the pin didn't go in as far as it should have. On the second sub tranny, the torque converter was correctly installed and the pin easily slid in and out.

Now, on to the question of what damage was done to the first sub tranny by forcing the torque converter back while bolting everything up when it was not properly seated? The Bentley manual warns of just this potential but doesn't expound up what type of damage is done. I'm guessing that the pump assembly is damaged. I'm also guessing that I'm not the first to have made this mistake. Anyone with experience know if my first substitute tranny is fixable and what needs to be done?

Thanks,
Joe
