06 5.9 / 48RE starts off in second gear
 

Hi,
I have searched a few threads, but haven't found anything conclusive regarding my issue. When I first start my truck cold, the transmission hits all gears. After it gets warm, it starts out in second, and sometimes will not even go into first even if downshifted manually. I just replaced both the transducer and governor pressure solenoid. I used the proper fluid (+4).. This never happened before I replaced the solenoid / transducer - I was having the 1-2-1 shift issue and that went away. After replacing the 2 items, the truck shifted as it should have for about 2 weeks, then started in with this issue.

Any ideas?

Thanks in advance!

Mike
