Cold oil is thick, which requires the HPOP to work harder. I have not found a diesel truck that will run smooth when it is initially started up after sitting over night, in cool tempatures. It has been getting down to the 40's where I live lately. My truck runs rough for about 1-2minutes. Then it smooths out. How ever your Hpop may have occured damage when that oil line blew. Which may cause your rough idle.
For the O/D light flashing you will need to take it to a shop that does transmission work. They have the equipment to run the diagnostics on the transmission, it could be one of several sesnors, or it could be a seloniod in the valve body, it could be the TR Modual. The only way to find out is have a trans shop scan the transmission for trouble codes. Which a regular code scanner is unable to do.
