06 Saturn Vue transmission issues
 

Brand new to this forum and I value the time of each you that may give me input or advice.

My vue has the Honda motor and transmission and recently began giving me issues shifting. At first, it would drive normally for about 10 minutes, then once it down shifted, it would not shift up into third gear. I pulled over, shut it off and waited a few minutes to start, the issue would go away for a few minutes, then repeated the issue again. Now, it will drive normally for a few minutes then begin the issue. If I allow it to sit while it's running, it won't even go into any gear, including reverse. It has about 270k miles.

I've drained and replaced the transmission fluids, twice. I've pulled the solenoids out of the side of the trans, near the battery box. pulled the linear solenoid, the other one on top of the trans. Tested them all and they all function as they should. I'm thinking it may be a pressure switch or something or a solenoid deeper inside the trans.

No codes

Thank you in advance.

What is the engine doing when it don't shift?

Engine was running fine, still
running fine.

grcauto8453, The car's been sitting and I'm now back on the hunt to get this thing driving again. Any ideas?
