Just installed the MN12 into my T/A
 

just got done the tranny swap to the MN12, holy hell its nice.

before in 6th gear @ 2k i was at 78mph. now w/ the GTO tranny im at 68mph.

im rowing through the gears alot faster and more often now. i cant wait to see what it does at the track

here the specs of the 2 trannys

fbody z06/gto
1st - 2.66 2.97
2nd - 1.78 2.07
3rd - 1.30 1.43
4th - 1.00 1.00
5th - 0.74 0.84
6th - 0.50 0.56

and thats through the 4.10s lol im guessing it would b equivalent to about 4.30ish rear gear.

what do you think?

so 6th gear is like ... not useless??????

sweet deal man....

exactly.... lol

sorry i threw it in the wrong section.stupid newbs.

-brandon

looks like a nice streetable alternative to gearing the crap out of your car... hows does 4th gear feel? looks like a pretty big jump between 3rd to 4th

4th pulls real nice.

this should work out great for street/strip/road race setup that i have.

if atco is open next week ill be there seeing if i can hit a new best and get a 10sec time slip. we'll see

holy crap, youre gonna come out of the hole alot harder now! best of luck my friend!

is the MN12 any stronger than the standard f-body box? or is the difference ust the ratios?

yeah please tell me, because im tired of breaking transmissions!

its a lil stronger from what ive heard and also due to the ratios, which was the main reason for my choice,

Im just trying a new/different setup since im only 1 of a handful of ppl that have done it. and see what it yields

-brandon

i hear this trans shifts smoother... something about conical shaped gears?

yea its a lil smoother.

are you gonna be making it down to the south meet in 2 weeks? i saw you post in the eastern section. ill give you a ride sometime at a meet.

-brandon

i won't be able to make the meets because i work on saturdays. i'm gonna try and catch you one day at atco when it opens and i finish up my car. i just posted up in your thread on ls1tech.

yeah i saw. if the track prep is good ill be there trying, but if the traction is crap in the coming weeks, ill just be testing and get a feel for everything.

Let me know when you go, i could probably ride up with ya or meet ya at the track. i should have my trans in this month, if not- early next month. and i just have to make sure my AAA is renewed lol

sounds good, ill try to remember, most the time when i go im by myself that way theres no distractions. ill see what i can do
