Another A4 question
Another A4 question I was gonna post this in the other A4 thread but didnt want to jack it.
I have a 1995 Firebird Formula A4 with a posi 2.73 rear. I also have a Jet Stage 2 Power Module. I am under the impression that this a shift kit. My tranny in performance and regular mode both shift around 6,000 rpm. The only difference being that it shifts much harder when in performance mode. Especially when in first if you let it shift around around 4,000 rpm, it seems hardest. It will chirp tires as low as 3500rpm when shifting.
Anyway, is this the Jet 2 module or may my tranny have a shift kit in it?
Why don't i have 1st? I have noticed some people talk about shifting into 1st gear, I dont have one. Why? I have 2, 3 D. Is this normal? I have noticed on 3 different Camaros (all V6's same trans though) that they have 1, 2, D, OD.

With 2:73s GM had to block off 1st gear.. You have to cut a little chunk of plastic out to access first gear. On the firebird they have 2 modes for the tranny. The Camaro is always in "performance mode" and that is the best mode to be in. I dont know why exactly.
I was corrrect by shoebox. The Camaro is not always in performance mode. He says the tables are different and the Firebird's performance mode shifts harder.
So what piece of plastic do i cut? Why does it matter if i have 2.73s? I am not sure that they are even still in there. 1st gear shifts at about 47mph and 2nd shifts around 93. According to this chart http://www.f-body.org/gears/ I have somewhere in between. Will i have any ill effects if i remove this plastic piece?

My bad.. 
Shoebox is the man..
It had to do with noise in first gear (they have to below a certain DB).... no ill effects...The plastic is on the shift plate..(take it off and you should see it)

Don't know much about the jet stage 2 module so I can't help you there, sorry. You do have a 1st gear but gm made it seem like you don't. If you really want to use it which I don't know why cause you're not hauling anything with a sports car, right?
All's you have to do is remove the top portion of the center console, and towards the rear of the shifter (after second gear) there is clip there that keeps you from using 1st gear (break)/remove the clip and then you will be able to select 1st gear. Hope this helps.

The plastic was put there so you could not get manual Low with 2.73s. the reason was to get past a sound test. the 2.73s would not pass the decel sound test in 1st gear so they removed it 
BTW the Z28 is not it perf or non perf mode they flat out have different talbe but can be programed and wired for perf mode. My car has it

I'd just like to be able to stay in first gear. Alot of times from a roll i will need to shift into first. My trans wont shift in any above 30mph. I know my gear is longer than that so i figure i could safely downshift up to like 40mph. Hell my 2nd gear downshifts at 85mph. I can replace a tranny mount and i have an entire Posi 3.23 rear i got for $10 on ebay if my rear end brakes. Our timing chains dont snap do they? That's where i would be scared.
On the subject of timing chains, how does one breaking actually damage an engine? I mean i know the valve hit the pistons, believe i tore apart a mercedes 420 that was proof enough of that, but when the cam is release all of the valve are closed corect? I know on my TT DOHC engine all of the valves were closed when i removed the heads. Just something i had always wondered.
