I have a 2008 ram 1500 4x4. It will not shift into 4th or OD. When I put it in drive it starts out like in 2 or 3rd gear. When I restart the truck and put it in drive then it drives normal. After driving it a few miles it drops back down to 3rd and wont shift into OD. CEL is on. What is the problem? Any thoughts?

4th is an OD; the RFE has two OD gears. 3rd is the 1:1, 4th is .75:1 & 5th is .67:1. What you have is a failure of the OD clutches. I would be willing to bet money when you pull the codes (why haven't you already?) you will have p0700, p0734 & p0735. If so, your choices are replacement trans or rebuild yours.

Ooohhhhh, you might be lucky then. Most people change the solenoid pack with this one and usually good to go afterwards.
