How do a buy a solenoid, harness filter, pan gasket or other part?

You can buy most small parts for 01m from me.  Just look at our shopping page and you can pay safely through paypal. shopping page

Should I change my fluid?

Yes. Volkswagen calls the fluid “lifetime fill” which is baloney.

Which trans oil would be best?

Of course for best results use the OEM fluid.  G052-162-A2 is the correct OEM fluid.    I can sell you OEM Pentosin or FEBI/Bilstein brand.  This is the exact right OEM fluid for 01m.  to buy fluid or any other 01m small parts click here ---->01m shopping page Use any other fluid at your own risk. But, I run Mobile 1 Multi-Vehicle in my own car. And I have several customers that have used Peak Multi-Vehicle in their car, and they report good success.  One of the oil companies sells a “global” fluid that formally listed g052162a2 in its spec sheet.  We’ve been offering that, as a cheaper option, and it’s been working perfectly. A customer pointed out that O’reilly auto parts had a “global” fluid that had the g052162a12 number right on the label.  (they have since changed the label and it no longer shows that).  We’ve used that also.   Also some folks on the internet have reported good success with Valvoline Max Life Multi-Vehicle fluid.   All these are RED fluids.   The simple fact that a fluid is red DOES NOT make it incompatible with o1m.

Should I do a flush? Will a flush cause my trans to fail?

Yes. You should do a flush. No one changes it since it’s “lifetime fill”, so it always looks bad. A flush will help clean it up. No, a flush will not cause your trans to fail. This is baloney and I get real tired of hearing this “urban myth” repeated.

How do I do a flush?

You would need to remove the cooler and hook special fittings with hoses on them to allow the Trans pump to push the fluid out, while you maintain the Trans full. Most people don’t want to buy the fittings so they just do a “drain and refill” again a couple days later.

How many quarts / liters do I need?

Fluid and filter change takes 4. I would have 1 or 2 extra on hand for valve body removal, because removing the valve body will allow “trapped” fluid out, and if the pan is off for long the torque converter will “drain” out a certain (unpredictable) amount. For the flush I use 9.

Should I graph the TCC with VCDS?

Graphing is for your peace of mind. Do it if you want to. This is the only way to verify your surge is a TCC problem and not an engine problem. You must scan the TCM with VCDS to confirm you are triggering no transmission trouble codes.

How Do I Reset Trans basic settings (reset adapts)?

Use VCDS or other full function OEM compatible scan tool. This shows how to reset transmission computer basic settings using VCDS.   taken from ross-tech site.  click here for more info-----> First, make sure there are no fault codes in the Auto Trans. Then, with the key in the on position, and engine OFF. Do not touch the accelerator pedal. [Select] [02 - Auto Trans] [Basic Settings - 04] Set Group to "000" [Go!] Press accelerator pedal all the way to the floor and count out loud 3 seconds. [Done, Go Back] Release the accelerator pedal.   It is normal for there to be no explicit instructions or changes on the screen when you do the above procedure. The transmission controller does not provide any feedback that it has been successfully performed.  For 09G transmissions, Basic Settings group 001 is used and the accelerator pedal is NOT touched.  

Should I do the Kerma Mod?

I've driven a few cars with the Kerma mod done with the adjustment rammed all the way in, and they drove terribly! Clunking and banging on up shifts and downshifts. I've also read of transmissions that had this mod running hotter. This happens because the higher pressures tend to move the pressure regulator valve farther into the bore which tends to cut off torque converter charge, which is the same oil as cooler flow. But, this mod seems to be necessary on cars that have performance upgrades, but there has to be some control. I recommend 4 clicks. This raises line pressure from about 55 to about 70. Do not ram the adjustment all the way in. I can undo the mod and adjust it 4 clicks. Your car may flare on shifts after undoing the Kerma mod, until the computer relearns. Resetting adapts with VCDS may speed this process.

O1M Sensor Locations

G68 Output speed sensor. It’s under the Left Side transmission mount. The bolts in that mount are stretch bolts so buy some new ones to replace them when you take them out. Notice that it unplugs over by the solenoid connector so most “checks” would be made over there. G38 Sun gear speed sensor. It may be called input speed sensor, but that’s not really its function. G22 Vehicle speed sensor. It’s used for cruise control and speedometer, but not for trans functions. F125 Multifunction Range sensor. This provides input to the TCM to let it know what position you've placed the shifter. It also provides reverse lights and starting only in neutral and park.
