Transmission light comes on around 40mph. Was periodical in the mornings and reset and was fine for about a year but is constant now around 40 mph. There is a lot of talk about the TCM. It started shifting hard, almost redlining before the shifts. Has around 120,000. Was recently serviced, no metal in the pan. Im going to try a used TCM and praying it will do the job. Reading up all day and problem is common but symptoms vary. Anyone had any luck with this situation on a 95 325i?
