I'd say you should expect to pay around $300 for the dealer to do a trans service.

 

I was quoted $400 for a transmission flush for my 2019 Z71. Luckily the replacement was covered under the 5/60 warranty since I had the shudder issue.

 

Mine was right at $300 at a local trans mission shop . Dropped pan , changed filter and flushed and filled.

 

My dealer quoted me like 400-450$ for a full flush and filter change.

 

The chances of getting a full fluid exchange for the prices quoted, from a dealer, are minimal. None of my dealers within a ~30 mile radius do a fluid exchange when quoting or performing a "trans fluid service." If the service advisor says they do then ask if you talk talk to a tech directly about the service. I had one dealer say (and charge for) a full fluid exchange with 12qts of fluid and they I even said "this is for a fluid exchange, right? Not a drain and fill?" and they said yes. The next time I had the service done I had a different service advisor and I asked the same thing, he said no, they don't do that for transmission fluid service. They just drain, replace the filter, and fill.

I called another dealer and asked if they do a fluid exchange or just drain and fill, they said drain and fill.

I called an independent shop and asked...they also only do a drain and fill.

It's also important to make sure they don't do a fluid flush, like with a BG machine that uses solvent and can cause more problems than a simple fluid exchange. If it's a drain and fill then the $300 is on-par. If it's $450 then I would make doubly sure it's a fluid exchange.

I hate it when service advisors lie or make things up just to appease the customer, and it's even worse when they charge for a service that they didn't even do.

 

My dealer has the price on their website along with oil, diff and transfer case fluid change.
go to where you set up for a service appointment and it might be there, as I think they all use the same system.
