Once again this dang truck is frustrating the crap out of me, seems it can't go more than a week without wanting a new part. So problem seems to be a shift solenoid, it won't go from 2nd to 3rd. No codes at all.

 

Try to manually change the gear from th #1 to #2 to od to verify its a shift solenoid.

 

Is the od light flashing. And does the od light work?

 

 

Truck shifts 1-2 on the colum but not to 3. OD light works but is not flashing. I'll go through that chart to check everything I can

 

I don't understand how that would verify that it is a shift solenoid. Please educate me.

 

Since you know , why not help in your "normal" condescending way instead of being a jerk .

 

This way is more fun.

And maybe he knows something I don't and there is merit to what he's doing.

 

The OP still needs help . Levity aside .

 

Idk if this is normal or not but this morning I hoped into the truck to drive the 2 miles to work and it shifted into 3rd. I won't get a chance to look at the truck today, we are running eggnog and that means a 16 hour day. I'm already 30 minutes into pasteurizing whole milk. Tomorrow I may get a chance to look at it after court. It really sucks to be so broke you have to fix your own stuff, but then also be working 60-70 hours a week.

 

Yes he does. I saw several posts that list what he can check. I don't have anything to add to those, they covered the subject very well.

If the manual shift idea works, I'm all ears. But I can't see how manually shifting 1-2, then going back to automatic mode proves anything.

That leads me to guess that the leading candidate is a stuck 2-3 shift valve. But that's just a guess based on the fact that it did shift to 3rd one time.

 

When my avatar had an auto i did this constantly because my shift solenoid from second to third gear was stuck and by manually changing gear it by- passed the solenoid and it worked, I dont know if the e4OD is the same but it's worth a shot. Im by no means a trans expert its just something the op can try

 

When you move the shift handle from 2 to OD it puts the transmission back in auto mode. The shifts are controlled by the solenoids, so this does nothing to determine if the solenoid is the problem or not.

 

Like I mentioned Worked on my Z, I dont know if the e4od is the same but worth a shot
