The car is a 2005 cadillac cts with just over 100k miles, and the issue I'm having is it is very slow to shift into 2nd gear, and when it does finally shift, it shifts very hard into 2nd. The trans does not seem to slip, it just takes a long time to engage 2nd gear. Every other gear feels perfectly fine. This only happens in 2nd gear.

I was thinking the shift solenoid was bad, so I dropped the pan and tested the resistance across the terminals with a multimeter, and it came out within spec(I also checked all of the other solenoids accessible from the bottom and they all checked out out within spec)

Any have a shift solenoid go bad in their cts? If so did it measure within spec? Is it possible the solenoid is still the culprit even though the resistance checks out fine?

The only other thing I can think of that may come into play is that I have set a P0128 code which has to do with the car not getting up to operating temperature quick enough(guessing a stuck open thermostat). Maybe the car is staying in gear longer to try to warm the engine up? That still doesn't explain the hard shift though.
