rear end question previous owner replaced the rear end in my car. 2000 TA with an M6. it's a 3-channel instead of 4 now. when the low traction light comes on (wet road, dirt/gravel on the pavement, etc.. when i start to go), the gas pedal becomes stiff as ****. is that normal? also, it doesn't have TCS, but would it still have posi-traction/ limited slip or whatever? lol i don't do burnouts. tires costs to much for me to do that on a regular basis, and i don't want to risk breaking the 10-bolt. probably only reason why i haven't put 4.10 gears in it yet.

can i have tcs even though it says it's off on the instrument cluster? the light almost always says tcs off and flicking the switch doesn't do anything. also, the light could be off, and then it'll just come on on it's own.
i still want to find out if it has limited slip and what gear ratio. i don't know what they changed when they threw the new rear on there. i know the gearing ain't the same. speedometer is off after i hit 55

If tcs is switching on and off by itself are you also getting the abs inop and/or brake lights? If so it means something is up with your wheel speed sensors, typically runout on the reluctor wheel(s) on the rear. Abs inop is dangerous, if you are getting it pull the big brake fuse until you can fix it.
If it is just tcs I can't say for sure, but 4ch to 3ch conversion is non-trivial...search on here to see what is involved. Were it done, I would think that you, shouldn't see that light come on at all.
Gear ratio is easy, put it on stands, put it in neutral and count the number of ds turns it takes to turn the wheel one revolution. To be sure on the LSD you can pull the cover and look at the diff. Yellow springs is the clutch type auburn, weird looking worm screws is a torsen, and of course open spiders is an open diff. If you don't care about type just spin the tires and see if both wheels lay rubber.
I'm in NH and I like it here a lot, people are nice, hunting is good. It reminds me of Arkansas were it a very wealthy state with awful food. I also love Arkansas, one of my favorite places...if I could make a living there its probably where I'd live.

I can't see your sig cause I'm on a mobile, where are you? I didn't know you were in Ar. I've spent a lot of time down around Fordyce, Benton county, and done a lot of rock climbing at Mt. Mag. And Sam's throne. I'm from OKC, family in Ark...nearly home to me
.
Have a look at your backing plates and see if you have a 2 wire sensor on each rear wheel. If you do, that's a 4 channel rear. If it is and you have a dial indicator with a lever arm you can pull the tire(s) and measure the runout on the reluctor wheel...you want it as low as you can get it. If it really is 3ch...previous owner may have done something weird, I'd have no idea what it could be though.
Afterthought: before dorking with the reluctors you might check for codes. I believe it will tell you which wheel is a problem. .that wheel could have a bad sensor too.

Cool man...you are in a pretty rural area huh? I've only driven through that part a couple of times.
Your problem is weird. It sounds like the tcs may be pushing on your foot but the abs inop isn't turning on...post up if you have a remedy, it would really help to know if your wheelspeed sensor wires are hooked up and to where. Like I said, he may have done something weird.
