ok guys. i dont know to much about gearing and gear ratios in a tranny so if i go from the 3.82 gears to a 4.05, am i even going to notice anything? the 3.82 is technically faster?

And my tranny just took a **** so if you have one for sale, let me know. LSD only please.

the lower the number the faster the theoretical top speed, but at the cost of acceleration. so if going from a 4.05 to a 3.82 you will accelerate slower, have a higher theoretical top speed, and rm while cruising at the same speed will be lower.

your better with the 4.05. it performs better and is stronger than the 3.82.

Isaac Lewis

ok. so im not losing any acceleration at all?

and do you have a tranny? haha

You would gain acceleration going to a 4.05, but lose top end speed.

I think I better start looking for a 4.05 LSD just in case, those things are going to be worth their weight in gold soon lol.

Isaac Lewis

ok. so when i go from 3.82 to 4.05, i wont need to change anything? it will just bolt right up?

Contact lnfwagonss if you want a trans built better he has a lot of options for you

Isaac Lewis

i would but it would probably cost me alot of money. i found a 4.05 LSD with 65k on it...got a great price. 450 plus a stock supercharger.

^ that is your best option but it won't be cheap. Jason would set you up with a nice trans but it won't be for $1000.

That's a great price for a 405 LSD

Isaac Lewis

exactly. and if i had all that dough to shell out i assume i would have a nice paying job and in that case, i would have done an F40 swap by now.

Isaac Lewis

it is a massive blessing....my cobalt is the only car i own and it basically HAS to be running for me to have a job. im using a coworkers car right now....

calo247

you have a LSJ right?, they came with the 4.05

Isaac Lewis

i do have an LSJ. i thought they came with the 3.82 or the 4.05? i thought they had both? am i wrong?

3.82 is in the ss/tc lnf
4.05 is in the ss/sc lsj

Isaac Lewis

here is the wikipedia link.

you have it backwords. lol. can i take a turbod tranny and put it in a supercharged car?

i have it backwards? ive owned a cobalt for nearly 10 years, and been part of the community the entire time. im also a certified transmission builder. a random wikipedia article written by someone who likely has never seen a cobalt must know better.

the article has it backwards. the lsj has a 4.05 and the lnf has the 3.82. gm changed to the 3.82 in the lnf because the engines torque curve works better with a taller gear ratio. the 3.82 is also weaker because it puts more load on 3rd gear, and thats the reason lnf guys put the 4.05 lsj trans in.

dont believe me? look at the tag on your transmission.

Hey. He linked to Wiki. It has to be right.

Isaac Lewis

well if im wrong im wrong. i dont know much more than the basics on these cars. and what LNF's have the 4.45 then? is that a gear swap from another GM or something? here is a pic of the tag.

Sharkey

the 4.45 ratio came from a saturn l series, the cobalt never came with them.

Isaac Lewis

i see i see. well thanks for the INFO....damn you wikipedia. damn you!!!!!

And unfortunately that trans doesn't bolt up to our cars so the gears need to be swapped to our cases.

But in all seriousness, sharkey knows his stuff

I know Wikipedia isn't a viable source, but I'm still kind of surprised it's so blatantly wrong haha.

Good ol uni profs, "you can't use Wikipedia as source, but I will in my slides".

The Cobalt SS page on Wiki reads like a seventh grade book report.
