Here's a back pressure tester check it out http://www.amazon.com/Tool-Aid-33600-Exhaust-Pressure/dp/B0002SQW9S/ref=sr_1_1?ie=UTF8&s=automotive&qid=1300753341&sr=1-1.If you get a tester i can give you the instructions on how to test it.As far as your axle seal leaking there is only a few things it could be the axle seal itself the axle or the axle moving around too much.I have only seen a few leak and it's always just been the seal.You said something about they changed the axle did they change the axle because of the leak or after the new seal leaked?

They put in a new seal first. Then it leaked again so they changed both. Then they changed the seal again. Now its leaking again. It seams to have alot of movement in it. This is the forth time.

Like I said there is the seal the axle the case and the bearing that can cause excessive movement that can cause a leak.I would put some leak dye in the transmission and follow the leak back to it's source.

I will have to ask them about this. They say they can see it come from between the seal and shaft. If so, will I need to replace the bearing inside and how much work and money does this usally run. I dont think they could ruin that many seals. They been in buisness a long time and ive had good luck with them.

They should be able to figure it if they are that good and have been in business that long. They should be able to pull the seal and see if there is a lot of play where the axle goes in. To replace the bearing it's a lot of work and labor. Might be cheap to just find a used transmission if that's the case.

Do you know what years and models of cars the transmissions will interchange withmine? Just in case I have to get to that point. I really think it is to sloppy to seal up. Then I will have to price fixing or changeing it out. Thanks

Let me know if it get's down to replacing or fixing and we will go from there.I would have to search thru all the year's and match part number's etc. Which I don't mind doing for you I just don't want to have to do it for no reason.I could spend that time helping other user's with there car's. So keep me posted on what you find and I will be more then happy to help you out with that.

Drove the ls2 today. Seems to shift smoother than before. The rpm's going down the road seem to be less than before. Went to omaha and back and only got 24 mpg. The service engine light came on again. P0421 andp0431. Warm up catalyst efficiency below threshold bank 1 and 2. I guess more problems. My scanner does not give me misfires per cyl. On this car but the 99 sl1 I have it does. Dont under stand why it does that. Thanks

Are you sure you don't have a P0422 and a p0432?I can't find the one's you listed. Let me know.

That is what it says. They are in my chilton l series manual. And I did order a back pressure tester. Should get it this week. Thanks

I can't find the ones you posted but the code's P0422 and p0432 is the same code description warm up catalyst efficiency below threshold bank 1 and 2 I posted the code descriptions and the trouble tree's for you the first two posted ones is the code P0422 and the number 3 and 4 images is the code P0432. Let me know what you find.

The catalyst is a device used to control emission content. Although the catalyst is active as soon as exhaust gas is passed through it, this diagnostic will not run until the front and rear oxygen sensors are both in open loop. The oxygen storing capability of the catalyst is monitored by viewing the rear oxygen sensor's response to an oscillating air-fuel ratio. The ECM computes how a near-failure catalyst would cause a rear oxygen sensor to react to an oscillating air-fuel ratio. These values are compared with the actual rear oxygen sensor response. If the actual response deviates a calibrated amount from the computed values, this code will set.

DTC PARAMETERS
DTC P0422 will set when:

* Closed loop is enabled
* Engine Speed is between 1400 and 2200 rpm
* Catalyst temperature greater than 380°C (716°F)
* No front or rear, misfire, MAF, TP, purge solenoids codes set

DTC P0422 a (type B) DTC.

DIAGNOSTIC AIDS
Once set, this code should remain active. Under certain driving conditions the catalyst monitor test may pass. This condition may occur if driving the vehicle at highway speeds (high air flow) but if this code is set, and there are no exhaust leaks, the converter should be replaced. If a misfire code is detected, the catalyst monitor test will not run. Be sure to correct a misfire condition before replacing the converter.

Possible causes:

* Exhaust system leaks between front and rear sensors, or rear sensor leaking.
* Catalyst deteriorated due to excessive time operating vehicle with a catalyst damaging misfire.
* Contamination of converter due to incorrect sealant, fuel, or fuel additive.

So what is the pre-converter. Suppose I need to check the hole they put in the exhaust to check the back pressure at freeway muffler. Why would my scanner not show misfires on the ls2 but wil show them on the 99 sli. Ita auto x-ray 6000. On the front down pipe on the exhaust thereis a small rounded piece in the pipe, just down from the manifoldi dont no what it is or does. Is there anything else on my scanner to look for in the run data. Thanks I think I owe you more money.

The pre converter is that part right below the exhaust manifold that is attached to the exhaust manifold.I can't tell you why your 1999 SL1 shows miss fires per cylinder and your 2000 LS2 doesn't. So does your 2000 LS2 miss firing or have miss fire code's?I would follow the trouble tree's I posted there pretty straight forward they really don't have any scanner data to watch or look at. They just ask if you have a exhaust leak a miss fire etc. If you want to donate more feel free too.

We had a different scanner on it before and it showed misfires on 2 different cylinders. Plugs were good and tried different coil packs and it didnt change anything. I had it in the shop for that and it didnt help. Same shop as the leaky seal. No codes for that. May be I can him to try his scanner again. How do you donate more money? Thanks

Was it setting a code for the miss fire's?What cylinder's were miss firing?Are there still miss fire's?Does your engine burn oil?If so how much?I will find out how you can donate more money they change the whole site recently i'm still getting use to it.

You said there is no miss fire code's but is there miss fire's?Because it says to fix that before addressing the code's. If you have oil burning that can make cats go bad. Kinda funny how you have code's for both pre cats at the same time.
