Well, I've read the multiple threads on here about the intermitent T/C - hard shift - problem goes away after shutting vehicle off for a short time or replacing the intake and exhaust cam solenoids. I've replaced both of these this past week and still have the issue. I get no codes to pull, and the issue is so hit or miss, it's very hard to trace. I have checked all my fuses and the fuse block connections.

Any assistance would be appreciated.

 

What engine? 2.2 or 2.4.

 

No codes eh? Are you sure the code reader you are using is CAN-capable and is able to read the codes? If it is not CAN-compatible, it won't give you squat.

It might be worthwhile to drop by a Chevy dealer and see if they can get a reading with one of their units, which likely would be a more advanced unit that what we peons typically use.

 

The engine is a 2.4, this is in an 06 with 66,000 miles. I've tried the scanner that the local Monro Muffler uses and was not able to pull any codes. I will try the local dealer. Thanks.....

 

I have a 06 2lt 2.4with 60,000 miles my t/c light came on and the CEL showed exhaust cam solenoid code, I had the intake side replaced at 35,000. Anyway I replaced the exhaust soleniod and t/c light came on again for a few minutes off and on for a couple of days, but no CEL so I changed the oil as the solenoid is in in the oil passage area, after that it didn't come on again. So it worked for me.
