Could be an issue with losing boost from your turbo. Can you hear your turbo spinning correctly? I know some TDIs have turbos that are a little easier to hear than other for no apparent reason. Are all your vaccuum lines in good shape? Are the hoses from the turbo to and from the intercooler in good shape? Maybe when something (vacuum hose, intercooler hose) gets warm enough it flexes and leaks. Right when this happens you should pull over (if possible) open the hood and have someone give it a little fuel. You might be able to hear a vacuum leak or an air leak in the intercooler piping. It could also be a bum sensor that sticks at a certain value and when you stopped and restarted you unstuck it.
You need to start eliminating items or find any other symptoms you can to help narrow this down. It is a loss of power right, and that's what is keeping it in the lower gear? Or does it seem more like it is just stuck in lower gear?

I have a Toyota Corolla 1,6 year 1984. Well maintained, services up to date. Will it be detrimental to engine if I drive steep hills with the car? I have to climb a steep hill to reach work.

not if you drive it accordingly
steep hills are best negotiated in low fears with plenty of rpm applied
for example on a steep grade with a manual 1st or 2nd or possibly 3rd and the rpm around 2000 constant will cause it no harm
automatics will go to first automatically so keep the rpm at that mark
engine damage is experienced when the gear selected is too high and the engine is placed under extreme load so down shift to allow the engine to work easily
When going down hill select first and only use the brakes to maintain the 2000 rpm range and allow the engine compression to hold the car speed back
the rule of thumb for experienced drivers is this
you select the same gear to go down that it took to come up

My 2000 dodge neon jerks when shifting to 2nd and 3rd gear and when going up a hill.

Check the vacuum modulator on the transmission for a cracked leaky vacuum hose.

99 dodge durango wont shift into 3rd gear

If it's in limp in mode it won't shift out of 2nd gear. Get the trouble codes read. The solenoid pack is a pretty common failure. But don't just throw parts at it. Get the codes first.

What causes engine vibration in 3rd and 4th gears?

When synchros go bad they will NOT cause a vibration. They will make a kerchunk noise when you try to shift to that gear. I know. I rebuilt my transmission (Type: W59) because of bad synchros in 2nd gear.

I would look for bad U-Joints, or a bad carrier bearing. This could also happen if you went to a tire size larger than 31x10.5. The 2.7L 3RZ doesn't produce enough HP to run 33's. It will bog down on a hill in 3rd. You could also have some bad half-shafts up front. If you keep the hubs locked they may be dragging you down.

Are your tires chopped?

My car has trouble shifting uphill and in low gears

When a car is going uphill, it has to use more power to get up the hill. Most automatic transmission cars will automatically detect this, and shift into a lower gear to get the car up the hill easier. As you get to the top or let off the gas, the car should than shift into a higher gear to maximize fuel efficiency. What does your transmission seem to do? Not want to go into a lower gear, are the RPMs jumping up and down before it shifts?

Hard shifting

probably just your transmission being old and wear and tear catching up to it. engine braking is a good thing in a manual but since automatics cant judge how far to let out a clutch mechanism that doesnt exist to make it smooth, it usually causes more wear and tear than its worth. maybe time for a transmission rebuild and time to leave engine braking to manual transmissions. $30 brake pads vs $2000 transmission. hope this helps ya

GMC Sonoma Automatic Transmission Problem

The transmission is this truck is a 4L60E. It is electronicly controled through several sensors. It will sense the load on the motor mainly through the TPS (throttle position sensor).It is not uncommon for you to have to really press the gas to make it down shift. Alot of the feeling depends on gear ratio in the rear end. The 4.3 is a very good engine, but it combined with a high gear rear end and overdrive may really seem under powered. You can put a programmer on it to change all the shift and power feel.If you are not having a hesitation issue then it will most likley not be the tps. You may just need a fuel and air filter, not knowing when it was last changed. The programmer is the best way to get the feeling you may be used to. Good Luck

Desciption of the gear positions on the automatic gear shift

The gearbox normally shifts like this in "D":

1st gear to 2nd gear

2nd gear to 3rd gear

3rd gear to OverDrive

If you have the selector in "2", it will not make the final 2 shifts. "2" is nice for descending very steepo hills slowly, and also is nice to use coming down hills when it is icy/snowy, the engine will slow down in "2", and you will not have to depress the brake pedal.
