Transmission Fluid drain vs. flush

As you may or may not know, I had an accident a few weeks ago where I was run off the road. Everything was fixed and good until I was changing my oil last week. When under the truck, I found out that something I had run over in the process dinged my transmission pan and drain bolt and it was weeping fluid. Not enough to make drips in the driveway but there was residue on the pan.

I contacted my insurance company and they agreed to cover it under the main claim so I got a new pan and bolt as well as a fluid drain and fill (since you can't remove the pan without losing fluid).





The dealership said they used about 6 quarts of fluid to fill the transmission but I don't know what the overall capacity is. So here is the catch, I was due to do a fluid swap in the near future anyways. Since they did not technically flush the system, would 6qts of new fluid be enough to call it good or should I go back soon and do a proper flush and refill. It is about a $275 service so I would prefer to be able to wait until the next service time.

 

Unless you have a very high mileage or do lots of extreme towing in my opinion you would be good with the drain and fill you just had and call it a day.

 

Truck just turned 70K and rarely pulls a trailer. A boat occasionally but more often than not just a yard trailer taking little loads here and there.

 

I would leave it alone. The 6 new quarts is just fine, IMO.

 

Why 6 quarts??? Dropping the pan and refilling it should be about 3 - 31/2 quarts. 6 just seems to be too much. They are not draining the torque converter. That would be in the range of 12 quarts.

 

Because stealership!
