One question if I may... Are you doing the replacement or the shop? If the shop is doing it then I would only do the a and b solenoids as it would be cheaper due to labor costs. Drain, drop one pan, replace two solenoids , if no issues with the pull pins should take less than 30 minutes. If you replace all 5, they would have to drop both pans, then they would probably charge you for two gaskets also. Just my two cents.
