Hard Shifts into 3rd gear and into OD- E4OD

[mthayer]

I got a hard shift from 3rd gear and on. Shifting into second is smooth, going into third its hard and then into overdrive. Doesnt seem to slip any. I can put the lucas tranny stop slip in it and it will clear up. Any suggestions, ideas? the OD light is now blinking, going to have a tranny shop run the codes on it but have to find some time to get over there. Strange that it was shifting hard today while I was pulling a backhoe and then after I drove about 70 miles with the backhoe on it started shifting smooth and then the OD light started blinking. Smooth shifting all the the way home after that. As Will Ferrell said in Blades of Glory, its Mind bottling.

Mine shifts hard into third when it is cold but seems to be smooth after it gets warm. I think i have read that this is an early sign of it going bad.
