Am I missing something here or is the dealer loco? Read the instructions on the forum on changing the transmission fluid and it sounds fairly quick and easy. Pull the drain plug, drain, pull the fill and level polug and refill with new fluid. Can't be over 1 hour to do? Due to my busy schedule right now I was just going to have them do it with 93000 on the wifes car but for $280 it can wait until I have time. So what am I missing or is there a more complex service for this? We want to keep this car for 200-300000 miles, she loves it.
Thanks people

You can do it, others have. There is a thread with pictures, illustrations and instructions.

It is more involved than that. Per WOT "Oh and the Volt's numerous coolant systems also use specific long-life coolants and require a "vacuum" type fluid replacement tool that all dealers have (and most competitive shops as well). There is also a correct process/sequence that MUST be followed in order to do this and prevent possible air cavitation or entrapment that could result in critical components over-heating. (Li-Ion battery, HV heaters, pumps, electronic controls, ICE etc)
This information is available in the Volt's service/repair data that would also be obtainable via on-line subscription by any progressive automotive shop that's on top of things. It is not recommended these services be performed by anyone other than a trained service professional.

EDIT: Consider it paying a dollar every 350 miles for the peace of mind that the job was done correctly and will not give you trouble for the next 100,000 miles 8^) That's my plan, anyway.

Most likely they are selling you a transmission flush and not a drain and fill. The transmission on the Volt does not need to flushed. I would recommend against it since it uses and cleaning solvent to help clean out valves and other passages in a normal transmission. A drain and fill is all that is needed.

Just an FYI they are discussion transmission fluid change. Your post referring to WOT is about the coolant systems. Completely different topics.

Boy, did I go off on the wrong tangent! Thanks!
