Drove to work this morning and my light popped on. Read the codes at work and got those three. Added some fluid and cleared the codes. Drove it back home and it did it again. Im thinkin about changing the input and output sensors as well as the fluid...any suggestions guys? Hoping the trans isnt gonna poop on me...

 

I changed out the sensors, removed the filters and drained the fluid....will be making another thread to explain it all.

 

When you had the transmission pan off, Did you look at the side plate on the valve body?
