po741 error shifting problem
I have 1996 Sedan Deville with the Northstar engine. I have just devoloped a problem while driving on the highway. The transmission will suddenly feel like it went out of gear and slipped into neutral. This usually occurs after going over a hill. After about 3 seconds it will go back into gear and resume normally. It dosen't do it at every hill and is completly unpredictable. No code would register until recently. The only code that comes up is po741.
Any help or insight is greatly appreciated.
