Well, I got my MIB and 2600 stall installed, and all went well. Drove to philly, and back (around 500 mile trip) and started to notice a buzzing sound when engaging OD from park, and the opposite. Then the truck stumbled while doing it one time, and now it doesn't do it all the time, but just once in a while.

The 1-2 shift is nice n crisp, then 2-3, and 3-4 shifts are slowly getting worse and worse. I have only gone WOT 3 or 4 times, and 1-2 was decent, but nothing like the other 2 trucks i have ridden in with ftvb only.

The truck is back at the shop which did the build. I am pissed.

Do you have any ideas of what went wrong? Anyone?

 

Post / email to Gregg Evans in the Factory Tech forum in NLOC (if you haven't already)- he should have some direction for ya...

 

I second that, he is a good man and stands behind his work.

Sounds to me like something is assembled wrong in the Overdrive clutch, who did the build?
