ok i learned since my car doesn't have the 1st gear in my shifter that it has 273 gears and i found a T/A that should have 323 gears...so i was wondering if i did a swap would i notice a big difference in the cars speed and power?

 

Not alot..... A little bit quicker off the line... I would suggest 3.42s for a daily driver...

This is an automatic??

 

yes an automatic.... i have 94 camaro camaro z28...stock and i spun a bearing and i am pulling a motor out of a T/A so i was gonna take the rear end out too...it has the first gear so i figure it has the 323 gears...

 

I did that swap and wished I would have went to 3.42s

 

for as much as i'm paying for the rear end i looked up and i could by 373 gears for the same price....so i think ill just do that...

 

Check the glove box of the TA... Codes for rearend..
GU2 = 2.73
GU5 = 3.23
GU6 = 3.42

For an auto, daily driver, I suggest 3.42.... If a weekend warrior, then 3.73.. I use 3.42, because is less wear on the engine, trans, rearend, etc. at highway speeds...

 

GU5 = 3.23
GU6 = 3.42

Hi n2ceptor, I have a 94 z28 with a 2.73 and i recently buy a 3.42. What i need to install the 3.42?

 

You can cut the plastic stop off at the shifter to get into 1st gear. If you have not already. I cut mine off with a hack saw, it took 30 seconds.

I heard 93-94 F bodys had the 1st gear lock out, for some reason. Like noise or?

 

I would wait and find a 3.42 rear. I did the swap 2.73 to 3.42 when my car was an auto. Perfect for a DD.
