Thanks for this information. Extremely useful! Going to switch my n92 solenoid today.
#1
2 N89 energized in 2nd and 4th to apply b2 brake
1 n88 feeds k1 clutch and b1 brake
5 n92 energized on each shift to cushion shifts
3 n90 feeds k3 clutch
4 n91 TCC solenoid7 n94 controls apply to b2 brake
6 n93 pressure control solenoid
Note: This pic can be confusing because the solenoids are not pictured and the valve body is upside down basically. It absolutly is labeled correctly and can show you where your solenoids are located you just have to look at it and pay attention, and compare it to your valve body.
Please dont post questions regarding problems with your car in this thread. If you have a question start a new thread.

Auto trans fluid change or flush will not make a trans fail. Stop spreading the wives tale/urban myth.

Firstly, a very big thank you for your contribution, you are a champ in my book!
The information on the 097 TCM pinouts and solenoids has helped me tremendously in understanding what to check/test for on my tranny.
Being a victim of water under the drivers side (RHD) carpet leading to TCM corrosion, I've been hunting around for 01M/01N TCM pinout diagram/explanation. My TCM Pin 25 corroded off completely.
Am now hoping that you or another member make the TCM pinout info on the (01M/01N) available just like you did for the 097.
Vag cable and 2nd-hand TCM on its way soon.
*I am a novice so please excuse me if I am crossing any lines or making mistakes in this forum dialog.*

I bought this 2002 Beetle for my daughter in Aug 2010 and it has 86K on it. It just started happening but it drives and changes through all the forward gears great, but there is no reverse. I am planning on taking the A/T pan to see if there is anything noticeable and to inspect the valve body and seals.
I know it is all electical and with the solenoid prices cheap I would like to buy solenoids and replace the solenoids that are responsible for the trans shifting into reverse to see if that helps. Nothing comes up on my OBDII scanner and I have a ohmeter/multi-tester I can use.
While this thread is helpful I can't tell which solenoids control reverse. Is it the same as 09A tiptronic trans, the solenoid #'s match, just not sure if they are the same for the piece of crap 01M trans. VW shows the 09A trans solenoids that control the reverse are: N88, N89, N92. Are they the same for the 01M trans?
I know from searching online it could be any of these areas:
1. Lip seal on the B1 clutch piston
2. Cracked reverse piston
3. Linkage bushing
4. Solenoid issue
5. Faulty reverse apply clutch
6. Faulty reverse brake clutch
7. Valve body
Thanks for any input and time put in to helping me. John

John, pull the shifter down to low at 20 MPH. If there is no engine braking, it's the B1 clutch/piston which is usually caused by bearing or gear metal tearing the piston. If there is braking, it's the B2 drum. Spring retainer comes apart, makes a big mess you'll find curlies in the pan. Either way, not a solenoid issue.

Rich, Here's a good one. A friend bought a piece of crap late 95 Jetta w/OBDII. Someone put a 096 in it and sold it. Of course it had a speed sensor code cause one's missing. I gave him one a he drilled the boss out and put it in even though I told him it won't work because the solenoid setup it different- #4 isn't a 5 ohm and it's not for the TCC. I don't see too many 096's anymore but if I'm not mistaken, the K3 is splined directly into the damper with no clutch as an AOD. I told him to just get the correct 01M but the car is barely worth it. I'm pretty sure sol#4 is used in 2nd & 4th. Did U ever hear of any way to rewire and maybe solder in a resistor to satisfy the computer?

Nice thought but no. OBDI & OBDII. PCM & TCM will not communicate.
