Shudder in OD only

I am having a shudder in OD only going down the road. I checked the carrier bearing, and its good. I have heard of TC shudder. Is this what I am experiencing? It starts to shudder in the gear before OD, then it shifts and it really shudders esp in low RPMs. If I mash it and it shifts into passing gear, the shudder immediatly goes away. Any ideas?

sometimes even if you wiggle your u joints and they don't have play they may still be worn out and need to be changed.

Yep. It turned out to be a couple of injectors missing. When you put it under load, lugging it, it makes a shudder. Doesnt do it in the higher rpms cause its not lugging so much.

Were the injectors bad and have to be replaced or was it a wiring issue ???

Oddly enough I had the same problem with my 6.0 & I had 2 injectors that went bad and were collapsing at the lower rpm - when the trans went into OD.

I dont understand it - but replaced the 2 injectors and problem went away. That was 10,000 miles ago.
