2001 jetta tdi automatic transmission will not shift into high ge

Once again, not enough information given. How many miles on unit? When you say does not downshift do you mean when you press hard on accelerator pedal, or when you slow down? When you say does not shift into overdrive do you mean high gear or torque converter does not lock? The cars are know for transmission problems and while sometimes you get lucky, usually they require a rebuild or replacement. How often do you replace the fluid and filter?

Ok , so you got home , parked it and when you started it up the next day and shifted it into reverse... backed out... and went to shift into drive , it stayed in reverse ?
Have you checked to see that the cable has not disjoined itself from the shifter to the trans.?
Are you able to engage Park?

2001 Volkswagen Jetta TDI

THE 5 SPEED AUTOMATIC TRANSMISSION

At the bottom of the automatic gearbox (tiptronic) you will find one threaded plug on below surface, (follow red arrow in the picture below). This is for emptying.




The oil level threaded plug is placed on the car front lateral automatic gearbox surface, (follow yellow arrow in the picture below).



The filling oil plug is placed on the upper automatic gearbox surface, (follow green arrow in the picture below).


Automatic Transmission Fluid (ATF) checking:
1. Requirements for check:
1.1. Vehicle standing on level surface.
1.2. Transmission must not be in fail-safe mode.
1.3. Shift lever in "P" position, parking brake applied.
1.4. Engine idling.
1.5. Air Conditioner and heater OFF.
1.6. ATF temperature must not exceed 104 Fahrenheit degree (40 Celsius degree) at start of test.
1.7. Automatic gearbox oil capacity: 2,5 liter. Only ATF with VW designation may be used. Do not use any lubricant additives.
1.8. Automatic Transmission Fluid ATF - part number: VW G 052 990 A2
1.9. An ATF level check when transmission oil temperature is too low results in overfilling, when too high results in underfilling.
2. CAUTION: Too much or too little ATF will affect the operation of the transmission. The ATF level must be checked at regular intervals.

Don't forget to rate my response. Thanks!

Automatic or manual? They use normal fluids, unlike Audi's (powersteering) where some needed the synthetic green stuff or else the seals would go. There are really good synthetic fluids available that are much better and last longer. Check out the VWvortex forum for lots of great VW info.

Transmission will not upshift I have a 2001 Jetta TDI - recently started the same problem. It is stays in one gear (the third) - Will give a reasonable speed of 65 miles but at high engine speed. I got a check engine light. I read the code using my OBDII tool and it shows as turbine input sensor malfunction. You can read my post for more details

Have you checked your transmission fluid?

check it out for oil level is correct, see for oil viscocity condition if require please change it, most of the automatic transmission come with power transmission oil or the TQ oil, see any electrical failure b'cause the auto transmission work with certain electrical relay circuit which are connect to the ECU check for it working is proper or fail to work, if possible see for the nearest VW, AUDI, SKODA authorised dealer or service centre for solution this problem see you soon...!

the transmission works properly after restarting so mechanically the transmission is fine
Run the fault codes to determine the problem area ( TR, TCM, VSS ,solenoids and servos) check for wiring harness problems and water in the connections

Unless you have a check engine light on or other electrical warning for the transmission chances are the transmission is failing and needs an overhaul.
