Hard Shifts
Hey guys, I just picked up a pretty nice HHR Panel wagon to use for my business. I got a good deal on it, so I assumed I'd have to do some work/have some work done. It's pulling 3300RPM at 60MPH on the highway, so I'm assuming it's not shifting into 4th gear. It's also shifting hard into 2nd and less hard into 3rd. When you first drive it and it's cool, it shifts smooth into 2nd and 3rd.
No codes stored, no check engine light.
I've read about the solenoid causing issues, but being that 4th seems to be missing, do you guys thing it's even worth jacking with the solenoid? Or just drop it at the trans shop and bite the bullet?
Thank you!

Welcome
Question. Is the Check Engine Light on ? If so, pull the codes and see if it points to a trans problem. Post any code numbers here. Numbers only.
Also. Certain trouble codes will cause hard shifting. GM’s way of telling Joe consumer to get the car checked.

Hi Corey, to the forums!
Is the CheckEngineLight (CEL) illuminated? If so, post the alphanumeric codes here, don't bother with the descriptions, they are often misunderstood. You should be able to get the codes read at your chain auto parts store for free.

Sorry, no codes and no CEL. I meant to say that in the post.

No code, no light. Post updated with that info. My bad!

I'm going to get it up on my lift and check the fluid tomorrow. I've already been under it once and at 150k miles it's crazy that there aren't any leaks. No oil, no trans fluid, nothing.

Fixes start with cleaning the MAF sensor with specific MAF cleaner..
