year and model helps, how long since the tran oil change and who did it, how many miles on the truck 2 wheel or 4 wheel.

Welcome to this forum! I've moved your thread to the transmission section. Did they drop the pan, and replace the filter? What kind of flush machine did they use? Was it a power flush?

If they used Dexron that's the wrong fluid. They should have used Mercon. However most fluids now are Dexron and Mercon approved. However if they used straight Dexron take it back and demand they change it to Mercon. And self respecting transmission shop should know this. If they really did make this mistake get it corrected by them for free and never go back to them.

she states dexro 3... sounds to me like they used the dexron/mercon 3 stuff.

verify what ATF they used. If it was straight Dexron, that's wrong. Take it back ASAP. If it was the Dexron/Mercon 3 (the combination stuff), that would be the right stuff.
