Oh that's right! You don't know about the S/C and the nitrous system I added!

Good point David. I've been through Gadget's site many times, as well as searching the forum. I understand what the end result of doing the upgrade is - I understand that it increases the fluid pressure in the tranny thus allowing for quicker/firmer shifts. The plates are also held together with more force for less slippage, and I think this is where the ability to handle more horsepower comes from.

My issue is not understanding what I'm paying upwards of $600 for (475 + express shipping two ways + tranny fluid). My only clue to this was a message that Chris (ravencr) once left here talking about IPT. He infers that the changes to the VB were springs and a larger jet to allow more fluid pressure. If that's what's going on for $600, then I'm really confused as to why there isn't a $100 kit that I can install myself. Again, _if_ that's all there is, then it seems that all the labor costs are on my side, so I can't see there being $400 worth of labor charges involved ($475-75).


Past that, here's my line of thinking as to why I'm asking this now...

I know that at some point I'll cave in and get a S/C - probably this summer. But, I'll hold true to my word and not do it unless I can afford to do the all the mods that are required to make it work right - i.e., fuel and the VB upgrade.

I understand the fuel issues, and I don't have a problem adding the cost of a fuel pump and injectors into my real cash outlay. So it's the cost of the VB that I'm trying to get my head around. I understand the requirement to have it done, I don't understand why it costs so much.


Thanks man.
