Beware, this is not plug and play TCM. On the other hand it won’t even communicate with diagnostics so you really can’t do anything with it.

I tried to get mine fixed but the company kept failing. So I bought this one off Amazon. I plugged it in and it worked instantly. All the codes went away. The hard shifting went away. I am able to use all my gears again. Nice product and cheaper than the cost I paid to try and have mine fixed.
