I have a 1990 honda accord and I think I have narrowed the sport light that wont go off, the car starting off and staying in 3rd gear and the tcu red light on to the tcu hvaing something wrong with it. You named all these weird parts I have never heard of and y ou said they were easy to replace so if I took my tcu out and looked at it would the parts needing to be replaced just be obvious and would they be easy to take out of the tcu? And also where do you get the new needed replacement parts? Also where could I find like a replacement tcu except from the honda dealer?
