Late 4th gen 10 bolt rear end on early 4th gen? Was wondering if I could put a rear end from a 2002 WS6 TA onto a 1995 TA without any issues. Currently has 2.73 gears, the new one would be 3.73, which I read is ideal for auto transmissions. There's one available locally on craigslist, and quite cheap. Also, if I did the conversion, what would be recommended to do about the transmission and torque converter? It's just stock right now (auto), I believe it needs replaced anyway because the car doesn't have the power it should. The car actually has more power when it shifts gears than when it is accelerating, it kind of lurches forward. It also feels terrible shifting at high RPMs, and shifting may be slightly delayed or late, it feels that way when accelerating from a low speed after braking, kind of "clunks".
Was looking at http://www.transamworld.com/2002-breakdown.htm
Did the 2002 manual trans even come with 3.73?

The gearing is 3.42. if you get the whole rear end with brake rotors calipers and brake lines with the e brake lines then it will bolt right up. just check drive shaft length. a sensor on top of the center section will have to be swaped from your rear end as well. Just remember the rear brakes on the 2002 are different than the 95.

Would it be a worthwhile swap for $100, considering everything else is stock too?
I'm assuming the brakes are better on the 2002 anyway, would there be issues with the distribution of pressure from the master brake cylinder or something like that?

If you get it complete, there won't be any worries. They fit the same and the driveshaft is even the same length. All you end up needing is a simple change in the ECM for the new gear to make sure the speedo is correct. You could probably do the whole swap in an hour if you know what your doing.

I swapped my 95 rear end for a 02 ta rear It was a great deal I got 150$ for the rear had like 7500 miles on it got brakes and all a very easy install. just rewire it so it plugs in where your plug is very easy One of the best things I ever got for the money

Some cars came with four wheel ABS. It'll have a sensor at each axle bearing.
Also, there's differences in the brake system. The brakes on the rear end need to match the master cylinder. As your vehicle is a '95, you should swap the '95 brakes to the '02 rear.

If you do this rear, it'd be a good idea to yank the axles and install some nice new bearings and seals.
How far are you gonna go with this car? If there's a fuel pump upgrade in your future, do it now as the rear needs to come down to drop the fuel tank.

It's not as simple as some people in this thread make it out to be. If the LS car had 4-channel ABS you won't have functioning ABS as the 95 only had 3 channel so you'd either have to accept that you won't have ABS or figure out another solution.
Additionally the LSX hubs are slightly LARGER so you will either need to grind down the wheel centers OR sand down the hubs themselves to get the wheels to fit.
Thirdly there are slight differences in the brake system due to the 4-channel ABS.
Everything else mentioned in this thread is correct though. Good luck.

While the rear axles are different between LT1 cars and LS1 cars, the front hubs are the same from '93 to '02. Moser lists Camaro/Firebird axles as a single number from '93 to '02, one for 3 channel ABS one for 4 channel.
I had used early wheels on my LS1 car without any fitment issues.

Thanks for all the info guys, but the seller sold it out from under me. Just have to wait for another to come along.
I did have my ABS disabled for awhile anyway, it was acting up. Changed all the rear bulbs and re-enabled it, works fine now, so it seems.

Sorry you lost it.
If this is a daily driver, I suggest you look for a 3.42 rear. There's little performance gain between it and a 3.73 but you will pay for it in fuel consumption.
About the brakes: The LT1 rear brakes have a spring loaded caliper and need a master cylinder with a residual pressure valve in it-much like a drum brake setup.
In fact, the MC for the F-body cars with rear drum brakes is the same as for the rear disc brakes.
Using a LT1 master cylinder with the later LS1 brakes and you'll have some pad drag. And, the brake pedal will also drop through a "dead spot" before it catches. I installed LT1 brakes on my '99 and ended up swapping in the LT1 master cylinder to make everything right again. It's not easy-one line to the ABS block has a different fitting on it.
