Toyota Repair: 96 Avalon Transmission Help, automatic tranny, steering rack

Question
How hard is it to take out and put back in an automatic tranny in a 96 avalon ? If i do this myself is there anything i should know that might be helpful ? I have been a mechanic for several years just never did a yota tranny before. Any help would be very helpful as my tranny is slipping bad and now wont even move the car in gear. Thanks for any response

Answer
On a scale of difficulty of 1-10 I would say it's about an 8, the engine has to be supported somehow from the top, the front subframe has to be removed, the steering rack can be disconnected and left in the car, once the subframe is out the transmission can be removed.
