I am sorry I did not elaborate more. Sometimes I do get overwhelmed with volume, but this is a very poor answer. I will give you more information but of course you can still get your money back.
The transmsissions pump pressure is off for some reason and causing hard shifting. It is hard to say which sensor. You would still need to at least have the trouble codes pulled before making a decision as to what is going on. It could just be a loose connector. Any Advance Auto or Auto Zone qill scan trouble codes fore free.
As far as the somke and low power, that sounds like the valve stems or leaking or even the head gasket may be bad. Yiou can borrow a compression tester from Advance Auto or Auto Zone. If you have low compression, you need a new head gasket.
I do apologize that you got such a short answer. With Automatic Transmissions I guess I just always suggest going to a shop because they are so difficult to work on. However you can still take a step or two before you know if you are still comfortable working on it and I did not give you that infomration. Once you get the codes back and look for any loose connections then you can determine what to do from there.
I am usually nver so abrupt with answers. So, I do apologize and I hope you would still come back as we have a whole team of techs who are really great.
I hope this information helps.
