<strong>Trans Am's and Formula's are the same when you are talking about gear sizes. They both come with either 273's or 323's.

I added a 3200 stall and ran last night and shaved my ET another .7 (13.49/12.73).

GU2 = 2.73
GU5 = 3.23

2. Did you install a "Trans-Go" or other aftermarket transmission valve body, or kit, to compensate for the increased line pressure to the transmission?

Wouldn't a torque converter DECREASE line pressure? You don't need a shift kit. I had a vig 3200 with 2.73 gears and it was fine.
And guess what, I didn't have to change carriers either. I went from a 2.73 to 3.42 using the stock shims. No noise. No carrier change. No hassle. And it costed me $300 installed. I had recently used LS1 Edit to correct the speedo, increase shift firmness, raise rev limiter and all that for $350. So, it costed me $650 altogether.
You can order a gear to fit 2 series carriers from www.mti.com

Re: TOTAL cost of gear install with everything included??? alright here is the deal...if u have 2.73's then it will be an extra 400 dollars for a bigger carrier to support the 3.23,3.42,3.73.or even 4.10's b/c the carries is too small for those bigger gears. i had 3.23's in my car so i didn't have to pay fot the carrier but i have a car that does have 2.73's and asked them about the cost and they told me extra 400 for a carrier. Just to let u know. and about a price without me having to buy a bigger carrier was a 660 total install for 3.73's in my daily driver with an auto.299 for the orginal gm gears from the dealer and 275 to instal them and the other little cash for the fluids and things.Pleased with all the great work of PYLE BROS. down in baytown. If u want gears this is the place to go..they do 4 cars a day...2 in the morning and 2 in the afternoon...u have to schedule either a 7:30 appintment and they finish around 12:00 or schedule at 1:00 and they will be done around 5. They did great work on mine and i scheduled for a friday at 1pm and i was out by around 4pm.Just let me know if u have any questions.

Re: TOTAL cost of gear install with everything included??? if u order the gears that fit the smaller carrier then they r not as strong and they WILL BREAK...just to let ya'll know..just spend the money now and get it done right. Makes sense smaller gears for smaller carrier=breaking or a bigger stronger gear for a bigger carrier=stronger gears and less likely to break but still possible.

Re: TOTAL cost of gear install with everything included??? The gears for a 2 series are not smaller or weaker. The ring gear is just thicker. Does that make it weaker <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

Re: TOTAL cost of gear install with everything included??? A higher stalling converter neither raises nor lowers the line pressure.
A shift kit, although desirable by some for the nice crisp shifts, is by no means necessary.
A tranny cooler, although advisable especially for really high stalls (read:4000 and above), is by no means absolutely necessary. Just so long as you can keep your tranny temps below about 210 degrees you're fine (and that's NOT hard to do with an efficient, moderately stalled converter.)
