Default What Axles to buy and transmission questions?

I have an 02 alh auto. I'm wondering what Axles are safe to buy. I don't have enough $ to go oem. Are there any other options that don't suck? Also, my transmission has been slipping every five days or so. Sometimes it slips going 1st to 2nd and sometimes in 4th. I got the P0740 code about a year ago and I haven't done anything because I just clear it and my rpms while cruising are normal. Why is it slipping on some days and then completely fine on others? Sometimes I will shut my car off when it happens and when I restart the transmission will shift properly. Is it worth it to buy new axles with a sucky transmission? Last question, will stiffer dogbone inserts make it easier for my transmission to shift? Thanks to anyone who can help answer these!

P.S. I'm looking on ECS and I see 2 non OEM companies that fit mine. GSP and OP PARTS. I also looked on NAPA and they have MaxDrive axles for pretty cheap. If any of those are good at all, let me know.

If you research this site it will not take you long to find automatic transmission woes and how bad that transmission is. Many people cure it with doing a 5 speed swap.

I would think spending money on axles with some gears in the grave and others on a banana peel is going to be money poorly spent. Are the axles bad? You can rebuild the original axles inexpensively.

Yeah I'm well aware of the 01m's repuatation but I was wondering if there is a specific reason that someone might know

Thought of it but I have always heard that that could cause more bad than good.

What's up with the axles? broken boots? The OEM axles are high quality and worth putting maintenance.

Driver side is ripped. Not horribly by any means considering there are no signs of problems yet, but I'm preparing for the worst. Also, I don't think it's worth it to put OEM in when the transmission is going out. OEM would set me back around $600+ and that's not too far away from what a 5 speed swap would cost me.

Inner boots are easy to replace. Boot kit is $25 per side. Outers are cheaper.

If the axles are not clicking and the grease still looks clean (not full of water and sand, etc.) then just put new CV boots on. If you need axles then check out Raxles Axles. Life time warranty and better than OEM.

But then why throw good money away if the trans is done? In my years of working on these things I have learned that by the time you notice something wrong (slipping, MIL for trans) the adaptive logic has been hiding the problem too long and the damage is done. Cost to fix, at this point, is usually always more than replace.

What would you do if tomorrow the trans said I've had enough I'm not moving this car one more inch? If you have other means of transportation do the 5 speed swap now and get it over with.
Your 01m has at least 230k on it. It doesn't owe you anything but could if it leaves you stranded far from home.

I should've been more clear. The transmission has around 100k on the rebuild. I bought it from a mechanic in my area who owns mk4's and he did the rebuild before I bought it. I still have him work on it and he has a full 5 speed swap at his disposal. Just need to talk pricing and labor. He said the only car he believes should get a manual swap is the alh autos.

That's a whole lifetime for that trans.

The 01M is a horrible, outdated transmission. I know because I drive one. However, mine has 185,000 original miles on it and still runs strong.

Lots of people are going to recommend a manual swap, which is definitely ideal, but these cars are getting so old that it's not even worth swapping them (buying a new manual car is nearly the cost if not cheaper than sourcing parts for the swap and labor). Thankfully, TDI ECUs have the option of switching over to manual mode, unlike the gassers.

So, if you have to stick with your 01m for the time being, it's not a big deal. They get a bad rap but they're not really as bad as some others. What they DEFINITELY are is temperamental when it comes to fluid and fluid level. Slipping in the trans can be caused by a worn valve body, worn clutches or too little transmission fluid. Fill level is CRITICAL in this trans for proper operation but they will run, albeit poorly, a whole quart short.

That being said, you can prevent complete failure of the trans if you take some precautions. The first step is to change the ATF and filter. This is well-documented and relatively simple procedure. You will need a few tools to do so, namely a fluid pump, torque wrench and an infrared thermometer. A proper fluid change and fluid level will likely make the trans shift better, however the change does not change ALL of the fluid in the transmission. You are replacing about 60% of it. Thus it takes several changes to get all of the bad, burnt old fluid out.

The other thing you should change is the differential oil. This is accessed on the top, back side of the trans underneath the speed sensor port.

As for your axle issues, stick with OEM axles. You don't need a new axle. Just pull off the existing axle and replace the boots on it. This is a messy job to DIY, and does require several specialized tools, so if it means taking it to a shop, so be it. But I did it myself in my garage, so you probably can too.
