My truck for some reason Just shuts off when going in reverse...but not all the time. I've checked transmission fluid levels are good and fluid color is normal. Don't know what it can be. It's been doing this for awhile now. I did some research but came up with transmission filter is loose and slides and cause it to miss and shut down while reversing. But honestly I don't wanna even mess with the transmission. Lol Any idea what it can be?
