How do I reset adapts?
After
certain types of repairs like transmission replacement, or undoing a overzealous "kerma
mod", or TCM replacement it is necessary to reset adapts on your Vw's trans.
Use
vag-com or other full function OEM compatable scan tool. This shows how to reset adapts using Vag-com (VCDS).
First
start the software and go into Auto trans
section.
Then
click on "adaptation"...
Make
sure channell reads "00". If not enter it in there. Then click "read"....
The
fields at the top will then change to "Note: Save channel 00 resets all Factory
adapts". Click
save and adaptives will be reset.
Should I change my
fluid?
Yes. Vw calls the fluid
“lifetime fill” which is baloney.
Do you recommend a source
for the filter and gasket?
I
can provide the filter and gasket
Which oil would be best?
It’s
politically incorrect and opens up a whole bag of worms when you ask if it’s ok
to use a different fluid. For liability reasons I cannot tell you to use
anything but the OEM fluid. I can get sued for that and would loose in
court every time.
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. Also some folks on the internet have reported good success with Valvoline Max life Multi vehicle fluid.
Of
course G052-162-A2 is the correct fluid as required by the OEM, and for best
results you should use that. You can get an equivalent Pentosin or FEBI/Bilstein brand,
usually mail order, but it’s expensive also and after paying for shipping it
may be best just to buy at your local dealer. Use
any other fluid at your own risk.
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 vag-com?
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 vag-com to confirm you are triggering no transmission
trouble codes.
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 vag-com may speed this process.
01m 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.
01m & 096 Letter code
locations
A replacement trans
must have the same ratio’s as the original trans or the TCM will see the ratio
difference and trigger a trouble code.
If the TCM sees a wrong ratio it assumes the trans
is slipping. You must verify the ratio’s are the same by the letter code. See the picture above and below for letter
code locations.
But what if you bought the car and the DAPO
(dumb ass previous owner) put a trans in there and you
don’t know if it’s the right one? Well then you’ll need to look at the label
that is under the spare tire cover on later cars or under the back seat on
earlier cars. Notice that in both the pic above and the pic below both trans codes are CLK.
Here’s where the sticker is on later cars. Sometimes you’ll just find it lying in
there.
