Houston, we have a problem!
I have an 2007 H2 SUT with~ 80K miles that I have own for about a year. It has been running fine untill about a week ago when it just would not shift past 3rd gear. It also has trouble shift from second to third also. To reach 60 mph, the engine RPM is almost 5K. AFAIK, there has been no modification or tuning done to the engine. Since I am not remotely anywhere as knowledgeable as a mechanic, I have no idea what's going on. Please help. Thanks in advance.
