just confirmed on the tranny today! Finally got my email for the build sheet.

Now instead of the sluggish sound at 40ish it's at 50ish. Plus sometimes when I hit the gas harder than normal it takes a hard hit so to speak.

 

Does it run better if you step on the gas pretty hard??

 

When in motion yes. From stop it more or less feels likes the truck jumping. (Torque converter? )

 

Have you tried disconnecting the O2 sensor(s)?

 

That's this weekend hopefully. I've been spraying pb blaster on both them this week. To hopefully help.
