intermittent hard shifting
Hello,
I was having serious hard shifting issues and replaced the shift solenoids which did not resolve my issue so I replaced the transmission all together with a used one. Now it will randomly hard shift, not nearly as often as before and it seems not as rough. I did have a mass airflow sensor issue and I put a new sensor in but still I randomly get hard shifting. I can turn off the engine and restart after 5 seconds and the issue goes away.
It seems to happen most often when I accelerate fast from a red light or when I pass another vehicle or when I am on the interestate traveling at higher speeds. There was a MAF code before I replaced the MAF but no other codes are showing.

2.2 or 2.4. There was no 2.1 in the HHRs.
Mileage ? How long have you owned it ?

Well. That sure sounds like a CEL or trouble code shifting issue. Did you pull the codes or are you saying the CEL isn't lit ? Even if the CEL is off there could still be a stored code(s). I suggest you pull the codes again.

As suggested, pull those codes again , just to confirm the MAF is functioning correctly. Look for any possible air leaks at the elbow to the throttle body.
