The car is having a problem shifting from 1st to 2nd gear usually when the car is cold. Dealer quoted $4,000.00 for new trans, and a repair shop quoted $3,700.00. The car is currently at AAMCO who ran a diagnostic which came back with only the trip-tonic code which they said shouldn't be the issue. Currently they are running an electric diagnostic as they believe the problem could be something other than the transmission and possibly something electronic.

Any ideas of what could be wrong? I have searched the internet and it seems there are many people with the same problem, but doesn't provide a clear answer of what the issue is/was. Seems most people paid for a new transmission only to have the problem return or more transmission problems. Any help would be greatly appreciated.

Regards,
E

I have the same problem..
a 2002 VW Jetta 1.8 T with tip trans.

when its cold it gets stuck on 3rd gear wont shift
till i press the gas pedal and the RPM goes to 60..
i also took it to Amoco said it was trans. but then took it to a family mechanic and said its not the trans. its electrical. I can honestly say its electrical he had it in the shop for about 3 months though.. what a pain in the butt .. well the last part he changed that made the great impact were the transmission relays..(about may of 09) worked fine till now.. its back doing the same..
he said it has to be electrical because other wise the trans. wouldn't shift at all. and obviously when its warm or so it works just fine..
well mine sometimes on some turns it messes up .. might turn again and works fine.. might just loose sensor or so I do not know.
i had also asked a UTI student that works with AUDI and said could be the transmission fluid.. but darn VW has a sealed trans so you cant do it that easily....

well let me know if yours gets

fixed

I have the vehicle listed above GLS Wagon. Just a couple days ago, I was driving down the interstate for 50 miles at 75 MPH. Then, I took an exit and came to a complete stop. When I tried to accelerate, the transmission acted as though it was in neutral. I could manage to get it to shift rough when revved up to 4,000 RPM's. This mostly happens during daytime. If I drive it more than 100 miles, the symptom seems to get worse. When I park the car and let it sit for 30-45 minutes, it runs fine for another 50 or so miles. I have tried taking the car to a well-known mechanic but even he is unable to find the problem.

This is a hard one due to two a length of time it takes to occur. It may be something sticking inside the transmission. Try adding some Lucas transmission treatment and see if there works. If it doesn't help you will need to take you to a good VW transmission shop. Good luck

Hi,

I suspect that when the vehicle is warmed up and driven that far, there may be a loss of line pressure in the transmission, That can be caused by a couple things. First, make sure the transmission fluid is clean and full. If it is and there are no diagnostic trouble codes specific to the transmission issue, I would recommend checking transmission line pressure. You will need a pressure gauge and VAG software to make checks. Here are the directions of how it is done. The attached pictures will correlate with the directions.

Main pressure, checking

Conditions for performing check

- Diagnostic Trouble Code (DTC) memory checked
When the DTC memory is checked, the following display should appear:
"No DTC recognized!"
- ATF level OK

Special tools and equipment

- Remove bolt -arrow- for main pressure port. Always replace bolt.
- Connect pressure tester V.A.G 1702 and tighten thumb screw.
- Start engine.
- Bleed pressure tester V.A.G 1702. To do this, loosen thumb screw and tighten when bleeding is complete.
If V.A.G1551 is used:

- Remove Data Link Connector (DLC) cover -1-.
- With ignition switched off, connect V.A.G 1551 Scan Tool with diagnosis cable V.A.G 1551/3A.

If there are deviations from the prescribed values, the following could be the cause:

- Switch engine off.

- Press fuse together and pull off connector.
- Start engine.

If possible, the main pressure test should be performed on a rolling road.

If there are deviations from the prescribed values:
- After test is complete, disconnect pressure tester V.A.G 1702.
- Install new bolt for main pressure port and tighten to 15 Nm.
- Fit solenoid valve connector.
- Once connector has been fitted, check and erase DTC memory.
- If necessary, install sound insulation.

Let us know what you find and if the pressure specs are within the manufacturer's recommendations.

Take care,

I'm assuming it's an automatic?

40 = 4000 (1/min x 100) rpm (revolutions per minute)

4 speed automatic? 5 or 6 speed tiptronic? (Transmission code would help as well as a scan for fault codes).

Does it shift OK when in Manual mode?

Did you check / add fluid at the correct time? Needs to be checked while in park, running and between 35c to 45c.

Have you done basic settings via scan tool? Have you tried to re-code the control module to Economy mode (if 01M Tranny)?

Just some thoughts that might help the experts answer your concerns. Provided you reply back with more info.

Hello,

Recently had the water pump changed and watched how they did it as they were placing the timing belt back on, I heard it click once counter clockwise would this cause the transmission not to shift correctly. Causing the RPM to be off. Transmission filter and Fluid have been replaced.

An out time engine will cause the transmission not to shift correctly to include an engine needing a tune-up

If your timing belt is off, you WILL have a "camshaft position sensor allocation" or "range performance" code. If your MIL is off, your timing is on.

My friend drives a 2002 1.8t jetta. He has some aftermarket parts on it, blow off valve, front mount inner cooler, and the exhaust was welded back on, along with the cats and has a small leak. He had his error codes cleared, and now the car jolts. Like I said, the car ran great before this. Error codes cleared, and it jolts like it's having a hard time shifting. Please help!

Transmission problem
2003 Volkswagen Jetta 4 cyl Automatic 67,000 miles

My car has just recently started Bucking upon driving and the car will not go switch over to any of the other speeds it's a 5 speed automatic, but wont go to the other speeds while driving it. The last time I drove it, it seemed like it wouldn't automatically change gears then after about five minutes it did a litle shift as if if had just warmed up or something and it was driving ok then.

Can you help me

Check and test the throttle poisition and vehicle speed sensors if okay get the transmission checked out could be a problem with a shifting solenoid/s

Could this problem possibly be related to an oxygen sensor. Because a few months ago I had a different repair and the dealership said I needed an oxygen sensor, but I didn't have the money at the time.

Could be the O2 sensor not switching accordingly to provide the fuel demand during acceleration

Any codes in the computer?A hard shift usually means there is too much pressure. We need to check for codes and also perform a transmission pressure test.
