Has anyone done this?
I am trying to do the "Tim Holt" trans mods and I am wondering if I should follow the normal or heavy duty shift kit instructions also Tim said no drilling if I had the sonnax valves which I do.... Do I still have to grind the throttle valve and seperate all three valve body parts to do this?. My truck is sort of all over the driveway right now, the valve body is on the bench. YIKES!! I just need better instructions from someone who did it.

I'm not sure Tim visits this forum. You might want to post this over at Dieselram.com to get an answer straight from the source.

(I'll be curious to know the answer as I have been looking into this mod myself.)

Nevermind. I see you already have.

I worked as a Tech for 10 years but didn't do much other than servicing when it came to Auto Trans stuff. Valve bodies sure seem scary:D

O.K While I am here talking to myself, should I adjust the line pressure to the normal or HD directions in the kit?

More is always better.

Seriously, sounds like I should do the HD direction then. Any more opinions?
