So my trans is shifting into 2nd pretty fast from a stop and i also feel the converter locking up in 4th right after going into 4th gear. I changed the fluid/filter the other night and the pan was clean other than some slight material caught on the magnets. At 85k it was cleaner than what i thought i was going to see.

Can anyone chime in on how their trans shifts as mine shifts smooth otherwise but i feel there is an underlining issue. NO codes either

 

Super quick 1-2 shift is normal. I've read you can code it out via VAG-Com but I haven't done it nor am I aware of the validity of the statement. No clue on the 4th gear deal though.

 

thanks - glad to know the 1-2 shift is normal - now i gotta figure out why the conv is locking up so quickly when entering 4th gear.

i have a vagcom but i cant find a code # i can use to update the system - i tried resetting the adaptations but the values 000 & 063 per ross-tech arent working.

 

So i read through countless threads all over the web and found a bunch of codes for different options and tried a few. Some said the codes posted were year specific and the system for older vehicle wouldn't take them. I found that to be wrong as the codes i tried all worked but its hard to tell the differences are as i just tested each one on a 1/2 mile burst quickly last night - Maybe ill see how each one acts over a few days of trying them out. I will say that none of the codes made the shifting in D or tip firmer which is what i was hoping for.

***********USE AT YOUR OWN RISK************


This is not my work so dont yell at me if its wrong or damages your vehicle - its your choice if you decide to code the vehicle from the factory settings. if you have corrections or new info, please feel free to post them up.


New vs. Old strategy shifting
The next codes are apparently for B5 generation vehicles, i.e. earlier than 2001.5.

All engine/transmission codes without EPC AND ALSO for 6 cylinder TDI engines, EU-II (2.5 L/110 kW V6 TDI) with EPC. (EPC = 'Electronic Power Control' and is Volkswagen's term for "Drive By Wire")

Transmission Code 00000
Old Strategy or vehicles without Tiptronic

Transmission Code 00010
New Strategy

--------------------------------
The next codes are for B5.5 generation vehicles, 2001.5 and on.

All engine/transmission codes with EPC

Transmission Code 00000
unpermitted code

Transmission Code 00102
(New Strategy) USA All Wheel Drive (4Motion)

Transmission Code 00104
(New Strategy) USA Front Wheel Drive (FWD)

NOTE: My car (April 2002 build, 1.8T) has a different coding, and will not accept the 00104 stock coding. My coding is:
Transmission Code 01104
(New Strategy) USA Front Wheel Drive (FWD)

I suspect this is true of the 2003 models as well.

When you first access the transmission controller, check the coding to see what is "stock" for your vehicle, and record the information somewhere, so you can return it to "stock" if so desired.

-----------------------------
Here's how to engage "Old Strategy" (from the Bentley):

For test purposes, control modules with "new" strategy can be recoded to "old" strategy.

To do this, set the 4th position from the left of the code number to -2- (e.g. 00021).

After completing the test, ALWAYS recode to "new". To do this, set the 4th position from the left of the code number to -0- again.

This appears to be ONLY for the B5.5 cars, since the table above already shows the difference between Old and New strategy coding for the B5.

So, from the table above for B5.5 one derives:
Transmission Code 00122
(Old Strategy) USA All Wheel Drive (4Motion)

Transmission Code 00124
(Old Strategy) USA Front Wheel Drive (FWD)

Very late model Transmission Code 01124
(OldStrategy) USA Front Wheel Drive (FWD)

I I've never tested this on anything but my FWD 1.8t April 2002 build. Presumably, it would work on all others, as per the Bentley. You may need to code to 01122 for very late model 4Motion.

--------------------------
Sports Mode

Sports mode on a B5.5 is engaged by setting a different bit in the same place (4th digit from the left). The bit to set is the '1' bit.

Since the B5 is already using this bit for "new" vs "old" strategy, it doesn't appear to apply there. You will have to experiment on a B5 to figure out what is what, if anything.

From the table above for B5.5 one derives:
Transmission Code 00112
(New Strategy + Sports Mode) USA All Wheel Drive (4Motion)

Transmission Code 00114
(New Strategy + Sports Mode) USA Front Wheel Drive (FWD)

Very late model Transmission Code 01114
(New Strategy + Sports Mode) USA Front Wheel Drive (FWD)

POSSIBLE CODING Very late model Transmission Code 01112
(New Strategy + Sports Mode) USA All Wheel Drive (4Motion)

I don't know if this works on other years besides my own, or on 4Motion. I know it does work on an April 2002 FWD 1.8t

-----------------
Putting it All Together
Finally, you can engage both, like I did. (At least on a B5.5.)

From the table above for B5.5 one derives:
Transmission Code 00132
(Old Strategy + Sports Mode) USA All Wheel Drive (4Motion)

Transmission Code 00134
(Old Strategy + Sports Mode) USA Front Wheel Drive (FWD)

Very late model Transmission Code 01134
(Old Strategy + Sports Mode) USA Front Wheel Drive (FWD)

POSSIBLE CODING Very late model Transmission Code 01132
(Old Strategy + Sports Mode) USA All Wheel Drive (4Motion)
