Transmission Torque Specs?

Does anyone happen to have torque specifications for an A340F Tundra auto tranny - like: torque convertor-to-flex plate, bell housing-to-engine block, tail housing-to-trans, etc....?

Thx!

No worries at all. Take your time and at your earliest convenience. Besides, I get paid on friday. Just wish the majority of it didn't have to go to mortgage.

I was on vacation for a few weeks and had 300+ e-mails when I got back. I thought I responded to everyone.
Again...... SORRY

Thanks DYOGIM for posting those specs.

This is some great info!!! Which may explain why the 17mm bolts would torque @ 53 ft-lb, but the 14mm bolts would not. And the Hayes manual just says 53 ft-lb (not two different specs). I just hope when I loosen and torque/re-torque the bell housing to engine bolts, I didn't damage the threads..
