Had the truck in the shop because of erratic oil pressure. Meaning it would drop to zero. The reflash for this didnt help so they ended up replacing the sending unit. I could go on about the first shop it was towed to but that would be irelevant. Ended up driving it away after one day and to it to a second shop 10 miles away. Thanks to Dave Fritzs website as far as listing the TSBs. I dont like to go into a dealer acting like a know it all but it sure is helpful having additional knowledge. Btw,the TSB # is 09-001-01
