i got of couple of questions. what does changing out my gears from my stock to say 4.10 or something to that nature? do i waste more gas or what do they excatly do? more performance? also what is this transgo shift kit everybody keeps getting? what does that do to? any help is greatly appreciated oh my car is 2000 v6 and i dont know what gears it has but its safe to say that they are stock.

4.10gears= quicker acceleration/less top speed
a shift kit makes the transmision have less lag between shifts and makes each shift firmer. you will probably get a chirp out of second gear. dont forget, these are only for automatics!!!

I wouldn't pick up a 4:10 gears unless I was turning it into a drag car. Thats a very very high ratio for a street v6. Auto 3.8 should be 3.08 gears(unless the y87 package) your best bet is going to be going with 3.42's

im sorry i should of mentioned it was an auto. so the gears will just give me quicker acceleration while the kit will smooth out my shifts. sounds good. where is a good place to get these items? and the 3.42's are better? i just want a little quicker acceleration off the line. thanks for all the help and quick reponses.

a good place to check out is ammperformance.com. he sells a lot of v6 f-body stuff and has a nasty little 3.4 camaro. talk to him if you need any parts.his name is josh

oh yeah, check your rpo codes for the gear ratio in your car. i think that it might be in you glove box, but it might be in a different spot than my car. the code for 3.42 gears is GU8. i am not sure but that should be the code.

4.10 gears are too tall for your application. I've got RPO GU6 (3.42 ratio) in my '97 RS. The Y87 option is nothing more than the Performance Handling Package (aka - bigger anti-sway bars).

4.10's are generally for pulling/towing. You'll have great 'off the line, but nothing at the end.' Your V6 would be well suited for 3.42's or maybe even 3.73's, but not 4.10's. You're not making enough low-end torque to warrant that high of a gear ratio.

Not only that, but your gas mileage will go out the window if you do any extended kind of driving.

If it was me, I'd run the 3.42's.

PS Have you thought about changing the servo in your 4L60E? Go to your trusty, local tranny shop.. tell them you want a fluid and filter change... AND you want to upgrade the servo to a "super servo". Basically, its the servo they put in the Corvette's. It will increase your band pressure giving you firmer, quicker shifts. Just a suggestion.

wow interesting fact there HPbyChevy. what do you recommend brand wise cause i remember my 93 shifted pretty smoothly and this 2000 is like driving in a standard. also can the dealership do this type of upgrade?? most of the tranny shops around here are just little holes in the wall and im threw with getting ripped off. thanks a whole bunch!

Umm.. the y87 package is a little more than jus some anti-sway bars. In fact this is from chevrolet.com

Performance Handling Package (RPO Y87) includes:

Zexel Torsen limited slip differential with 3.42:1 rear axle ratio for the optional automatic transmission or 3.23:1 ratio for the standard five-speed manual transmission, Dual exhaust outlets, and Sport-steering gear ratio (14.4:1)

So if he has a y87 he already had 3.42's and posi traction.

To the original poster, you still seem a little confused on the gears. 4.10's will give you a quicker acelleration but will cause your car to run at higher rpm's. This will result in your car hitting its speed limiter sooner, so you might want to think about getting a HPP3 or something else that will kill the speed limiter AND allow you to recalibrate your speedo. With the A4 I would suggest 3.42's or at the most 3.73's, unless you are just going to be racing all the time. For a daily driver though I would stick to nothing lower than 3.73's. (and remember in gears the higher the number the lower the gear) Also you asked about gas milage, the lower the gear the higher the rpm which means it will use more gas. Hopefully that will help out a little bit.

wow that summed that up. i think i will look for 3.42s since my car was like really stock v6. it only has ASR so i dont that i would have the higher gears. thanks a lot!

chesee48

yea from what i heard, get the 3.42's and u should be all good =)

i have 410s on my 98 auto and the work great if you don't mind bad gas mileage. and for them being to much for a v6 is BS because at the end of the 1/4 i run 3000rpm in 4th gear. ihave 3000rpm to go. my 60 foot time is 2.132. but if the speed limiter gets in the way or i would be running low 14s now.

Ive got a 99 V6 with intake mods, a flowmaster and some appearance things. Ive got 3.08 gears. I think if I was ever gonna change my gears, I would go ahead with 3.73. 4.10 is gonna be way too much for the street. I think 3.73 are good if you do some racing at the strip, yet you dont have to drive an hour to work everyday.

I love seeing guys pulling 6000 in fourth gear.... @ the Nascar speedways.

I think if your running 6000 rpm's in fourth gear, you've got problems... like the lower end laying on the pavement and the tranny fried like bacon. That stock-block V6 can't handle that kind of punishment for that many runs. And it makes no sense running that kind of gear set on the street. On the strip? Sure.

i think i will get 3.42's since i have the 3.08's. i just wanted a little quicker acceleration since most of the ricers here just like to race for like a couple of feet lol. whenever i try to launch my car feels like it is going to stall or something. what am i doing wrong? i keep the rpms around 1500 and my car is an automatic. whenever i am at a stand still it usually idles around 700. i think i am doing the power braking method?? i hold the brake down while keeping my foot on the gas till it reaches 1500. am i doing it wrong? any help is appreciated
