Impressive list

http://www.bonnevilleclub.com/techinfo/?article=54 RPO code list for ya

My tach reads about 2100 RPM @ 70mph. My final drive ratio as indicated by RPO codes is 3.33 (GX3). Yours sounds right to me.

You lucky bugger

GX3 - ratio, transaxle, final drive 3.33

yer tranny is VERY high geared so your revs will be high at high speeds...very good!!!

And for the record you dont have a Series 1 that started in 92, you have a LN3 3800 not the L27 (series 1)

Thanks Jim but I am a damsel in distress and need a little help still. I looked at the list and don't know how that tells me what the RPO code is.

RPO coding is the factory standard and options package that your car has. You have a GX3 RPO for the tranny. Its higher geared (higher then the SSEi) thats why you rev higher then normal at higher speeds.

cool! I knew she could fly. Thanks guys for the help!!!

Gearing doesn't mean higher rev'* at higher speeds. It just changes where the shift points are, so some speeds have higher RPM while so are lower.

i have a 2000 SSEI and the top speed in
1st is 52 mph at 5500 rpm
2nd is 98 mph at 5800 rpm
3rd is 126 mph at 4750 rpm
4th ?
74 mph is 2000 rpm in my car.
my car has a stock pcm.

UX1 says radio, am/fm stereo, weather, cassette, eq, etr, incls clock, what is the weather part of it???

What mods do you have? 3rd gear is limited to 109 at WOT in a stock 00 PCM. 4th is limited to 128.
