2005 STS 3.6
Now my car has P0700 code, just came up yesterday. TCM needing replaced. So, I can buy another TCM but then I am finding it must be specific to my car. So obviously not an easy switch. So, what are suggestions here? My mechanic will use a part I purchased but if this part is easy to get to, I could put in the new one. After reading a few things, it's not that simple. This car is my nemesis. 6k in repairs in the 2 1/2 years I've had it. After this is the differential bushing, my mechanic said 900-1000 to replace. Anyway, can I do this myself? I'm on a limited income and cadillacs are expensive for upkeep in my experience. Thanks for your input!!
