I have a 99 3500 dually. Its shifts perfect 99% of the time. Holds strong but call me crazy it seems to downshift everytime im turning left. Almost seems like the converter unlocks. Trans and converter have very little miles. Has anyone else had any problem like this?
 
Low fluid has been blamed for that in several instances. And, another time, it was a loose filter. Check fluid level in NEUTRAL, as without the TC full flow mod to the valve body, the level will show high in PARK. Give it a minute or so in NEUTRAL.

Ok. What is the full flow mod? And im pretty sure its full but will double check. Trans work isn't really my favorite thing
 
Nevermind the question about the full flow mod. Figured it out.
 
Less than a half a quart low but seems to do better.
 
Yeah, they get a bit picky. If it starts again, pull the pan, do a filter & fluid change & band adjustment. While there, put in a drain plug.

Thanks for the advice. My 98 I had had a deep pan with drain plug. Can't beat it. Real pain otherwise
