What are they?

I'm having a slight power engagement delay, most noticeably when the engine is cold, the truck seems to hang a bit high in the RPM's on the shifts, and doesn't drop down into a lower gear on decel when I feel it should.

The truck has felt this way since I put the Sonnax kit in and I'm wondering if I went just a little too far on the VB pressure adjustment screw. I haven't tripped a code or anything, but I just have a sneaking suspicion this might be it.

Also, if MonteC is out there, can I adjust this with an allen wrench without dropping the VB out? I think the nut is accessable, but I know its' right up by the rooster comb and might be a bit tight in there.

 

These are the same symptoms my truck has had for a while. Does it sometimes slam into gear, from takeoff, if you're not careful?

 

No Slamming, never had that issue. Just hangs a bit and holds a bit too long on Decel. I'm talking a very small amount, just noticeable if you've been driving it a while.

 

Yes you can adjust the pressure while the VB is still in the transmission. Try it and see what happens. Id also torque the VB bolts (7/16) down to 130inlbs.
