Car listed above is the limited model. Story I hear a lot, car runs good until slowing down and into first you feel hard down shift. Or if your going between like 20ish to like 50 and if you accelerate fast it will kick down. Limp mode? When either happens I can stop, put it in park, restart it and it will be fine for a bit. So I first changed solenoid. Nope. Then changed both speed sensors. Nope. Today I found a ground strap that was broken. Fixed it and nope.
Thinking about looking at wiring or TCM/PCM!
Please give me some ideas. I have to go through emission, it's been months with different codes.


*So there was 2 other codes I just fixed. Both MAP sensor codes. New sensor. Codes gone.
* Also about 6 months ago codes lead me to change cam and crank sensors.

Hello,

The P0841 code tells us the transmission pressure temperature sensor is out which will cause the issue you have described. Here is how you replace it in the diagrams below. Check out the diagrams (below). Let us know what happens and please upload pictures or videos of the problem.
