This Van starts to shift late at times, like if wide open throtel, but the TPS voltage and throtel % are OK. Had bad alternator which we replaced, thought this might be contributing to the problem but problem still there. No codes. Fills like if kickdown switch is stuck but I'm not sure it has one. Any ideas?

Have you performed the transmission reset? If not, try the following: 1. Turn on the ignition, without starting the engine.

2. Turn the ignition back to the off position.

3. Turn ignition on again without starting the engine and depress the accelerator all the way to the floor, holding the pedal there for a
minimum of ten seconds.

4. Release the accelerator pedal and then start the engine in the regular manner.

5. Drive the vehicle making sure that the transmission shifts through all four gears.

This model trans also needs regular (40K mile) changes of the filter and fluid - even per VWs specs.
Always use only the special oem ATF - golden in color. I've changed a couple that had high mileage without regular changes, and the shifting improved a lot. Here's a good kit with all you need:

The throttle is electronic - not cable driven - and the kickdown is adapted by doing basic settings on block 63 with VAG-COM, although the "reset" procedure mentioned may accomplish that also. There is no kickdown "switch" as such - the trans control just learns the correct reading of the pedal sensor in the basic setting procedure.

It would be nice if you provided the mileage of the vehicle, transmission service is definitely highly recommended as suggested and may improve shift quality and shift point.
Much nicer would be to have a scan tool to monitor the measuring value blocks to determine what is not working properly, torque converter speed, solenoids etc.

Sorry for the lack of info. It was late last night. The transmission has been rebuilt and has new fluid. Milage is 133K second transmission. When driving with the sanner I try to see all the blocks and they all seem to be normal. The PCM is comanding the particular gear is on. The problem is intermitant, it can be driving fine and then you feel a downshift when you decelerate and then it shift late. VSS and TPS and trans Temp. are normal. I have done the basic settings I'm thinking of buying the wiring diagrams to back-probe the TCM. I was not sure if this has been a problem with this Eurovans. Thanks for your response.

As far i remember those eurovan never had an issue with the TCM causing this problem. I replaced several TCM's but for internal sum check error which caused limp mode.

Interesting thing about your issue is if i understand correctly it shifting down by it self and if so it's usually caused by trans. fluid temp sensor, or overheating but you stated fluid temperature is just fine. What is your temperature reading while really hot?
Have you replaced transmission fluid cooler? was there any fault code in TCM? Could you monitor torque converter slippage and if so what's the reading in 3M, 3H, 4M and 4H ?

The problem was with my scanner. After using Ross-tech I noticed the transmission temp @133C but when checking with heat gun oil pan reads 111C. This transmission normal operating tempeature is between 110-120C. I,m in the process of replacing the internal harness even though is new. We have seen some internal harness failure. If this continues then I will go to the PCM directly.
It would be nice if VW would have a code for transmission overtemperature. Will post results.
Thanks

I thought there is a code, at 288F. Not sure if I made that up, or if my dull memory pulling that out of the cobwebs.

You can also try setting the tranny to sport mode and turn off DSP (via vagcom). This takes out the 'learning' aspect of the tranny and forces it to just obey rpm and load in order to shift.

Additionally, you can ohm out the pin for the temp resistor. Mine is out of range, so most likely the temp reading is off. Which way I don't know. I just know it ohms out about 40 ohms too low.

Updates for this van. We replaced the internal harness and we were not able to back-probe the TCM because of its location. The factory manual has the TCM picture located wrong, it shows the ECM location. The TCM is located right next to the drivers left foot.
Since we were not able to back-probe the TCM we decided to check it with a heat sensing gun and the results were as follows: Vag:51c heat gun:45C Vag:98C heat gun:81C Vag:127C heat gun:104C Vag:130C heat gun:107C Vag:132C heat gun114C. This leads me to think that the problem could be with the TCM program or the TCM. Does anybody know of a re-flash for this, or has seen this also? This overheating is a known problem with this O1P transmissions behind a 6Cyl, but I'm starting to think it may be a TCM related problem. Can anybody beriffy the same by using the data and heat gun in another EuroVan?

I'd expect the exterior of the pan or case to always be cooler than the fluid internal temperature, since heat transfer is from the fluid to the case. The offset wouldn't be constant at different temperatures and rates of heat generation, so I'm not sure your readings show that much of a problem with the VAG sensing.
I'll try monitoring the fluid temp on my 2001 to see what range I show.
As I recall the trans cooler may be in the loop where engine temp coolant goes to the cooler, then on to the radiator, as some have reported who added an external cooler to solve overheated trans. (Mainly on Riata.)

Regarding your auto. I had mine rebuilt at 128,000kms (its a 2000 TDi Transporter) and the rebuilt one has since done about 355,000kms and still going strong, which I contribute to 2 things, firstly to the external oil cooler (with large fan) which I fitted which also includes a temp. sensor and guage, and the second, which may be of interest to you, is that the guy who rebuilt my auto strongly suggested that I fit a later model (don't know the correct name) controller/computer that controls the gearbox. I was told that using the 2000 model one would result in significantly shorter life of the box. The new controller was quite differant to drive with, the changes were much quicker and more precise...... Now if I could just get hold of a wiring diag. of the Engine Management System, I might be able to get the motor back to a drivable state. Cheers...

We installed an external cooler but It would be nice to know what PCM you used, they are not cheap and dealer needs to program them to the new vehicle.

Did you get this problem fixed on th 01p? We have trans problem after reuild of hard 1-2 and 3-4. Works perfectly after relearn then act up after 10 miles of driving. No codes in computer memory.

Sory for the delay was out on vacation and just got in. Yes we did, the external cooler fixed the problem. When the transmission raches about 136C it goes into transmission hot mode, the reuslts is late harsh shifts, almost like TPS was stuck at wide open throtel. We also had no DTC's is your transmission shifting late? If so take a look at the temp.

I had a similar issue with my 1999 Eurovan. The transmission was shifting too late in 2nd and 3rd, at roughly 3500-4000 rpm intermittently. I read the post about doing the transmission reset above, tried it and now the car drives like butter. After a year of griping about that and talking to mechanics it was a big relief - because I know it was a poor feedback loop between the sensor under the accelerator and the TMU.

So - try it on yours - maybe you will get lucky.
