My 2004 6.0 has been doing this for a while now. In the morning when the engine is still cold, once I get into overdrive on the freeway it starts bucking. The only way to get it to stop is to kick it down out of overdrive or wait for the engine to warm up. Once the engine is at regular temp. it completely goes away. I have tried oil and fuel additives to try to clean up the injectors but have seen no difference at all. Any thoughts would be greatly appreciated. I am stumped!!!

Good luck with this site.
I know the feeling. I had the same problem with my '05 years back. I thought it was the transmission at first. Had a fella tell me it was most likely stiction with the injectors. I used RevX <<<I'm sure if someone does respond to your post besides me that it will be turned into a additive argument. Anyhow...RevX worked for me and I have absolutely no association with the ppl.. Pour in the oil and noticeable difference in my experience within 4-5 miles of driving. I typically had to use it half way into miles of a oil change. I have since put in new injectors and the problem has been resolved. GL

Sounds good I have tried the Best Line additive and it has been around 2000 miles. I have not seen a difference at all. I'm afraid it may be time for new injectors. I was trying to avoid that. Thanks so much for the response, I really appreciate it.
