Looks like I'm going to keep the auto for at least a couple of years so I HAVE to upgrade the VB.

Forged gets $800 + shipping, SPG gets $1000 and includes overnight return shipping. (Stillen isn't an option)

Are they making the same mods? SPG says, "This VB upgrade includes all NEW enlarged solenoids, O-Rings, gaskets, plates, etc..Basically a whole new mechanical system for the VB". FI may be doing the same thing but don't mention it.

FI can get it done it 3 business days, SPG is talking about 4-10 days.

Certinely both companies are trust worthy.

What's the difference?

I can't speak for SGP but the Forged Performance VB upgrade is outstanding IMO. I had it done about 3 weeks ago. My shop sent the VB overnight on Thursday and had it back on Wednesday (Monday was a holiday). The shifts are very quick and pretty firm. The tires will chirp through 1-2 and 2-3 under even moderate acceleration. Highly recommend the Forged Performance upgrade.

How is the shift from 1st to 2nd under light throttle ? To hard ? clunk the rear end ?

That's good news. I don't think anybody that has a FI VB has commented at all.

Does it also shift comfortably when not pushing it?

I heard that the SGP and FI VB when they shift under normal driving in 1-2 you get the clamp noise. They say it happens becouse of the nature of the new vb

It is firm but not too hard. When in full auto mode it's not bad and does not clunk the rear end. Under manual mode, it depends on the RPMs at shift. I notice if I shift at or slightly under 3k RPMs the shift is smoother and not as jarring when over 3k. Hope that helps.

Under light throttle and in full auto mode the shifts are firm but not real hard. I do not consistently get the clunk in the 1-2 shift; just depends on the rpms at the shift.

At first it is a noticeable difference from stock. After 3 weeks now I have really gotten used to the new feel and the firmness. I was most concerned about downshifts at first. Occasionally I feel a hard downshift and often times I do not. For a performance feel I would highly highly recommend the upgrade.

With the SGP VB . You have to give it enough gas out of the hole so it doesnt hit to hard . If you baby it [ normal driving ] it clunks pretty hard . Ive got used it and try when possible to give it the right amount of gas .

IMO I hear they are both good but im undecided becouse once you mod the VB you it cant be modded again so if someone builds the full tranny they cant mod the VB again even though you can just change VB with someone that has it stock.

One question doesnt the VB mess up the tranny though since the shifts are harder.

BTW SGP posted in their website in the VB page that the Clutch packs should be done in two months i dont know how old this is but thats good news if its recent.


I wonder how much its all going to be.

I'm certainly no expert but I recall Sharif mentioned that it actually may extend the life of the clutchpacks.

I know it helps it but if im not mistaken i heard if your tranny is not in great shape it will start to gring it down.

I am looking at going with Forged I for my VB when I get it done...

Should a Torque Converter be done as well when you do the VB?
