[RED BRAWN SE CC]

Fri. morning I started up the Titan and placed it in drive. As I am drving down the street I dont feel the trans shifting. I look down and notice service engine soon light is on and see the AT light blinking. I turn it off and start it again. Light still on. Drive around the block and the trans starts shifting again. Took it to dealer Fri afternoon. Service rep just called back and said the MIL was due to 2 trans codes. Said the "thump" may be related. I did not ask what the codes were, sorry. Said he has to call the Nissan tech line on Monday. Will keep you posted.
