I'm showing 4.5 to 5.5 hrs labor for removal and reinstallation of the tranny plus .5 for each expansion plug. Use a 50/50 mix or water and antifreeze. I would also recommend a complete coolant system flush now that you have put those pellets in there. Get that crap out of there ASAP! Also, I'd have them do all the expansion plugs in that area that require the removal of the tranny... you dont want to go thru this again in a couple months.
