This issue started about a year ago when the check engine light came on. Upon reading the code it said P1698. I recently took the truck to the dealership and they said the problem was my TCM. I replaced the module then after about 50 miles the transmission would slip out of gear and back into gear while at 65 MPH and the same shortly after. It didn't happen again. I put the original TCM back in it because I thought the new one was faulty. Then another issue came up where my truck would be very sluggish on the take off, as if my first gear was not engaged. This problem would go away and come back every other day or so. I recieved another TCM and the same problem has been happening except now it seems to not want to engage first gear at all. I am unsure if the problem is my torque converter or if my transmission is going out. Can you help?
have the same problem?
