The J32A2 and J35A3/A4 have the same bell housing bolt pattern, so a number of trannys will bolt right up. Bell housing pattern changed in 2007.
** Keep in mind, mechanically, the drivetrain bolts up and into the car with no modifications. Electrically, that is another thing. I cannot help you there. There are 3 or 4 re-pins required all together for the swap to be 100% ie: reverse lock out on the tranny, water temp gauge and 1 or 2 other things.. I can't remember them.
You can use a 5 speed auto tranny from a 01-03 Acura but, these have a design flaw with a lack of(?) or poor 2nd gear oil lubrication. Not recommended
What is recommended is a 5 speed auto from:
Honda Odyssey, 2002 up to 2006? (the guess/gossip on the Van tranny is they may have a bigger Torque Converter to handle the HP.TQ better)
Honda Accord, 2003 up to 2006
Acura TL/TL-s, 2004 to 2006
