The only other major issue is when in S and if you accellerate and let off the gas she won't shift and then out of the blue it slams into the next highest gear.

It's rare but that happens to me also. I believe it's only on the 3 to 4 upshift. Almost like it's searching...searching...searching...and then WHAM!

^ I found that a TCU reset is crucial after the VB install. I was experiencing a lot of strange things before my TCU was reset. When slowing down the trans would do funny things when shifting into first - sort of like the car didn't know what to do at that point. I was also one of those that was getting the 1 to 2 slam and, initially, a 5 to 4 slam (the 5 to 4 eventually smoothed out but the 1 to 2 never fixed itself). The 1 to 2 slam would occur in normal, sport and manual at very mild acceleration. It would rarely happen when cold but would always happen when the fluid was warm. It was the sort of shift that would snap your neck back and you'd expect to see parts in your rearview mirror. WOT shifts were always clean and crisp.

After my TCU reset at the dealer (<$60) the issues are gone. I noticed an immediate improvement when driving away from the dealer. Shifting is now quick and firm.

As you can see in this thread, ClimberD is a great vendor. He was always there whenever I had any questions.

ClimberD - I'll be sending my 2006 VB to you soon. Thanks for all you've done.

Have you gotten any feedback on power levels that people have been able to handle with your VB upgrade? I've been considering a VF52 upgrade with injectors and a fuel pump but I'd happily look at something bigger if others haven't had issues.

Great thread, ClimberD.
