Torque converter locks at 39 mph and no there is no adjustment. Seven years later if it disturbs you drive in "3" until you exceed 45 mph

When you are refering to your 2007 please let the readers know if it is a 2007 classic or the 2007(new body style).
My tranny problem was at 7k miles on my 07.

Suggestion - from now on, the 2007 "classic" should be referred to as a 2006-1/2. That way there is no confusion between it and the 2007 NBS.

my 2000 old style chevy pickup will shift out of OD on a slight hill then not shift back into OD. When this happens it will shift hard or jerk from 1-2-3.
 
What I did was add a qt. of Lucus transmission oil to help clean sticky valves. it did help, but it still does it every couple of months.
 
Just stop turn it off let it sit awhile and works ok.
????????????? who knows.

tansmission keeps popping out of gear as soon as it is shifted into gear shift light starts blinking and thats all it will do. Dealer spent 17 hrs labor and still couldn't diagnosis problem replaced tcm and shift solenoid. I have also had to replace neutral saftey switch twice truck has only 60,000 miles on it I would appericiate any feed back or similar problems solved.

1997 C1500 transmission slipping by jimm58

My 1997 C1500 trans has been slipping a bit for quite a while. I am trying to determine if it needs the VCM jumper kit to resolve the 4L60e slip problem. My VCM service number is 16229684, the service number of the fixed VCM is supposedly 16244210. Does this mean that I need to install the jumper kit (part # 12167310)? My transmission is exhibiting the symptoms of the TSB (00-07-30-026) that fixed the bad ground problem. Thanks, Jim

I have the 2007 1500 6.0 vortex max.
bought the truck july 5th was great for 3 or 4 weeks then
it started bucking or jerking going up grade, sometime at a stop light it would feel like someone hit me from the rear.
dealer says they can't find anything wrong.
also mpg dropped from 20 mpg to 16 mpg.
did your drop before your fix? and did your warrenty cover the fix?
