did i get ripped off?

Drop the pan change the filter, replace the pan and the refill with fluid. And yes there is always gonna be a certain amount in the torque converter that won't get changed but not enough to matter. jes my .o2

I've heard tons of horror stories, especially after I told my buddies I dropped the car off for the job, but in my experience it saved me from buying a new trans.

There is like 8 qts of fluid in the converter.

I had mine flushed and have had no problems it doesn't seem to make sense that a flush would cause metal to circulate. The trans pump is constantly circulating fluid the same as the flush would.

Read what BOB4x4 said. Flush it, dont use a cleaner!

Actually it doesent, it circulates it in the opposite direction as it would normally circulate hence the reason it stirs things up that would normally never move again. Doesn't matter to me what other folks do with their equipment but when a Quick oil change owner tells me that he'd never do it to his own vehicle because of all the problems he's seen that is good enough for me. Change filter and fluid and keep driving is what I do and that was good enough for my last 1/2 ton truck for over 350 thousand miles so I guess it's ok.

Thats strange when they did mine at the dealer the unhooked the return cooler line and thats where it drained out from.

Since you actually watched yours being done and I didn't I'll have to assume that your are correct and I am wrong unless they've changed the way they do things in the last few years. Either way I am personally convinced that flushing is taboo for a transmission period. If changing the filter and fluid every 60 thousand miles will net me 350kmiles of service I suppose I could afford another transmission. BTW while we are on the subject of flushing, just what is it suppose to accomplish. To my understanding it just pumps fluid through the transmission right. In my experience there isn't much better of a cleaner than transmission fluid to start with and the pump is already circulating the fluid every where that the external pump they hook up is gonna send it. If it was there it should have already been flushed out by the transmission pump and be caught in the exhisting filter. To each his own but mine will not get flushed. jes my .o2

I am not disagreeing with you just trying to understand I by no means have all the answers. I have heard and seen the horror stories w/ flushing but as other posters have stated the problem may have already been there. Would i flush a trans for the first time at 350K now way. I flushed my trans at 50K and I will probably not do it again for another 100k in between I will only do the filter.

My understanding of why a flush is needed. Trans fluid although it does have detergent properties it is also a lubricant. All lubricants have a life span. If you only drop the pan you are actually changing less than 1/2 the fluid in the trans and none of it in the TC. The 68rfe holds 16 Qts of fluid. So if you take out 8 and add 8 you still have 8qts of dirty used oil in the trans. I was getting some TC shudder before I took mine in for the flush and now its gone. I attribute that to the ATF losing its lubricity.

My cummins is the first auto I've owned so I know nothing of these things. I have the filters at home waiting in the garage for me to do the first fluid change (70k km's on the truck) Is there no way to drain even some of the fluid in the TC when doing a fluid change at home?

We have transmissions flushed all the time with no problems.

Does not sound like the most reputable source. They are out to make a quick buck, not take the best care of your vehicle possible. The reason they have seen so many problems there is because they don't know what they are doing.
