I just got my truck re-tuned today for my new gears (4.56s AWESOME), and we noticed somehing while driving it around.. in 2nd gear around 4-5k rpms it bogs down and then picks right back up and keeps pulling hard tpo the shift point.

But there isn't anything that my tuner could see in the scan that would have caused it. but yet its still there.

He was thinking maybe a pressure problem with the transmission, and we did check it and it was probably about a qt over-full. Would that cause something like that to happen.

Or what do you think it is?

thanks alot

someone please move this to GM tuning section srry.

 

Just to give more detail. Does the engine actually bog or does it just stop pulling for a second?

 

I don't understand the difference, its like it loses power, drops down 3-400 rpm and then revs right back up.
