question about the g50-33 transmission.

Is the first gear removable, or integrated to the shaft.
How hard would it be to replace the ring,pinion gear to a 4.0?

That's out of a Swiss 993RS and has a little taller 3-6 than the the other 2 RS trans

All the g50-3x have the same loose 1,2, though only the idler on 1 is really loose as the 11 tooth drive is integral to the mainshaft

Hi Bill,
Thanks so much for the information. For some reason I thought the 1st gear was removable from the shaft allowing me at a later time to change if I wanted to. I guess thats only an aftermarket feature.

I was planning to buy the box, send it to someone to change out the 3/4/5.

I currently have the removable 2nd gear box, so i will probably sell it when i am done. Should be an easy sell.

I reviewed most options, but since the box needs a new lsd, rebuild, 3,4,5,6 gears this seems to be the most economical way to re-gear.

3 + 3 + 4 = 10 k (still have the nasty 1/2 drop)

After its all said and done it will still probably cost me 8k once all said and done.

you can change th 1st gear ratio by changing the idler gear. The 13 tooth drive is built into the main shaft, the 41 tooth idler is loose and can be changed, if you use say a 42 tooth the ratio goes from 3.154 to 3.231, but that is a bigger one 2 drop, the lowest stock 1-2 drop is w/ the stock /3x 1 & 2

all the /3x use a 13:41(3.154) 1st, 21:41 or 40:20(2.00) 2nd
