If the MIL is indicating, get a scan done to check for trouble codes.
Seems the transmission is not engaging correctly and there are many possible causes. Have you checked the transmisison fluid level and condition?
The sttuttering after 4000 rpm indicates the engine rpm cut has been activated. This is built into the engine computer to prevent overreving and engine damage. However at 4000 rpm it seems to be lower than most and this is usually due to trouble codes detected by the engine computer.
