They never checked anything just automatically assumed it was going to need a new transmission. Took it to a different transmission spot to find out that there is no oil in it.

See if there's any codes on or anything like that. told me it was going to be $4500 for a rebuilt transmission.

After disassembling the transmission to get access to the switch, they told me they put the old TCM back in and sent it back to the dealer, when I remove the TCM, there were two bolts missing, and one broken off in the valve body. Needless to say I was very disappointed. My vehicle is back in service and running just fine. I cannot recommend this facility to anybody after my experience.
