i recently had my transmission fluid changed on my 2011 suburban at 125k miles, and its leaked transmission fluid ever since. I assume they did something wrong, but i have had it back several times and they cant figure it out. Any ideas? Also, this is the dealer doing the service which is even more frustrating...

thanks

Where is the leak - pan or somewhere else - drain plug or drop pan to change?

It's imperative to get all sealing surfaces clean and fluid free or the leak will continue. Some sealants require a pre cure time before assembly, if they're not waiting for that skin to happen it will leak, proper torque and bolt pattern tightening must be done to prevent leaks.
