I had transmission problems…
I had transmission problems around 120k miles and I called a transmission company and he told me if Silverado have transmission problems they take it out and replace because if you change the fluid you will still have problems instead I had the fluid and filter change the problems stopped for a short period of time and came back after about 300 miles I had a transmission company changed my transmission and the problem stopped I will try the disconnecting the negative terminal on the battery for 30 minutes to reset the (TCM) if I have future problems I do like the truck but not the repair on the transmission (that I believe it was too soon ) or the repair on my rear differential at around 120K miles (that I believe it was too soon)
