Yup, Best deal is a 4.3 LSD from an n/a wit hsport package. kills ure gas mileage though.

today at work i changed my rear differential fluid just for the hell of it, damn when i pulled that plug it had so many metal shavings on it i didnt know what to do with myself. i cleaned the plug off and flushed maybe 5 quarts of GL-5 80w90 through it to clean it up, then filled it. the grinding quieted down but is still there, its more of a hum almost sounds like grinding rotors.. my diff is probably on its way out. do you think that the speedo cable broke? or the sending unit. also i noticed the rear end clunks when you put it into gear (its an auto) how do you run a diagnostic on the tranny?

also, everytime i put my key to the on position my horn goes off non stop, so i have to turn the key to ACC then back to on for it to stop.. any way to fix that?

9 times out of 10 it is the speedo cable rather than the sending unit.

Here is a link to a page that shows how to get diagnostics for the trans.

I've got no clue about the horn problem though.

Good luck trying to fix an auto tranny yourself unless you're a mechanic. It sounds like you need a diagnostic/full check up done. For the tranny inspection just head down to a local tranny shop and ask them to run a diagnostic on it. They will remove the pan and check everything. I had mine checked and found out mine needed a rebuild. My jaw hit the floor when he told me how much a rebuild would cost. It's just the same price to get a brand new one installed. Around $3000 CDN I was quoted. I'm still driving mine, it revs high and shifts hard when cold...but it doesn't grind or anything strange like that. Yours sounds serious whatever it is.

the error is Defective No1 speed sensor (in combination meter)-severed wire harness or short circuit. code 42.... i just checked it outside. i guess thats not a big deal and as far as the hummmmm goes, thats probably my differential.. tranny seems to shift ok, i heardyou can experience irratic shifting when not having a speedo cable... i really want to figure out the horn thing though.. thats driving me nuts. and i guess ill just have to get a new LSD. anyone know of a company that makes one for our cars besides OBX.. ill check up on a KAAz right now.. they might

but if anyone knows anything on the horn situation let me know

The clunking is probably related to your metal shavings in your diff. Transmission usually dont clunk, They make other parts clunk. The only real thing you have to look out for with an auto is if its getting hot, or it slips. Otherwise theres not much to break on them
