6.7 trans lag/problems

[erabbit4192]

I have an 11.5 6.7 im having some pretty bad lag in between shifting gears its a manual trans. I know the trans can be retuned but I'm not sure to go about this or if this is even the issue. So anyone that can point me in the right direction I would appreciate it

I have an 11.5 6.7 im having some pretty bad lag in between shifting gears its a automatic trans. I know the trans can be retuned but I'm not sure to go about this or if this is even the issue. So anyone that can point me in the right direction I would appreciate it

Is it completely stock ?
Dpf still intact with no aftermarket tuner of any kind ?

It's an automatic don't know how the hell I got manual on there. But dpf and egr are deleted

i had that problem, take it in...they will replace the solenoid and reprogram the tranny. My tranny is great now.

Dealership replaced pump on mine, made no difference in the delayed shifting issue....

Yeah the "fixed" mine then it started acting up again. Went it at 99K miles and they put a brand new tranny in lol
