3.23 lsd

[Blizzard242]

There's a guy on the ls1tech that has 3.23 stock rear end for sale from a 02 transAm. As long as it has ABS thats pretty much a direct swap right? Also.. Are LSD's stock in transAms?

Re: 3.23 lsd

You need to find out if it's a 3 or 4 channel ABS. If the car has traction control, then it is a 4 channel ABS, if it does not, then it is a 3 channel. The difference is the speed sensors on the rear. A 4 channel ABS (traction control) rear end will have two speed sensors on it. One at the end of each axle. A 3 channel ABS rear will only have one speed sensor, on top of the pumpkin in the center of the rear.

Yes, Torsen LSDs are stock in TAs.

...or, he can skip all that and just buy the differential and gears out of it...Of course, that depends on if the seller is willing to remove said components to sell seperately

I'd have to want to bring my car to a shop to have someone install it then too. And so far I've been doing everything myself.. unless I learn really quickly how to correctly install gears and I'm not too sure if that's gonna happen.

^all you would need is a $40 tool from an Autozone to handle it

I thought you always ranted about how it was difficult as hell and you need to be within 1 thousandths of an inch to install those? Or.. do the gears and lsd come out as a unit and whatever needs to be measured isn't necessary. I'm so bad with drivetrain stuff.

Alright, say it's that easy to do. And lets say the seller is willing to do as said. Would I need different axles? I just remember hearing something about spline count that could make a difference.

As for right now, im gonna go look up some info on rear ends so I might have better questions.

Re: 3.23 lsd

3 channel should be a direct swap no problems.

setting the pinion is something i'd have a shop do.

i also couldnt pry my open diff out when i tried.

if you just want to change from an open diff to an lsd, you can keep your same gears.

Yeah I was looking to add a little more to my gear ratio while I was at it. 3.08 is nice for mpg but thats not what I'm looking for. Economy is the last priority when it comes to this car. It's also not my DD though.

Oh BTW, do all traction control equipped cars come with a switch to turn it on or off? I just know that my brother had one in his 00 firebird and I don't have one in either of my camaro's. Just that nice little storage place where I collect change a misc receipts.

The reason I warn against it is because most members on this site oversimplify the process; they think they can just slap the gears into the differential housing without measuring a thing, and everything will be peachy. It is only in those situations, where the board member demonstrates that they can't tell an empty differential housing from a hole in the ground, that I tell them to not attempt a gear install on their own

I'm so bad with drivetrain stuff.

nevermind then..for you, you'd be better off swapping rear ends

no

F-body to f-body, it doesn't matter

yes

Re: 3.23 lsd

Heh, in my defense though.. the only reason why I'm bad with drivetrain stuff is because I've not had a chance to work with any of it yet. I'm hoping that I'll go.. oh.. this isn't so bad, when I open the differential cover. That's how everything else has been so far. :cool: I suppose I could try, especially if you might even have a little faith smokepanther. :D

Re: 3.23 lsd

would switching from a 3.08 to a 3.23 effect you mpg that much?

Re: 3.23 lsd

not a HUGE difference. a switch up to 3.42's or 3.73's would make a pretty good dent.

i'm contemplating finding a 3.08 or 2.73 rear, cuz my car is my DD, and whatever mpg i can get out of it will be worth it lol

Re: 3.23 lsd

hmmmm. i might just stick with my 3.08 and stick a lsd in that.............

Re: 3.23 lsd

True, going from a 3.08 to a 3.23 really won't make much difference at all. However, the Torsen LSD that is in the TA 3.23 rear end will not work with your 3.08 gears. You might as well just swap the whole rear and call it a day. My best time for a complete rear swap in an f-body is 47 mins ;)
