wont shift in to overdrive

[JT1007]

I just replaced the left front axle. It was bad to being with. Got stuck in 2ft of snow drove home in 4 weel high in 2nd gear. Now there is a ticking some were in the front that was not there before. The differential was bone dry. It will not shift in to overdrive it goes through all the gears very fast. Any sugstions?

Do you have a flashing O/D light or a check engine light?

od lightflashing

the od light is flashing. when it wants to shift into od. not the check engin. when i restart the motor it's off

The flashing O/D light indicates a trouble code for the transmission. Find out what the code number is, and post it here.

Not every scanner is capable of reading manufacturer specific transmission codes.
