First, I'm not a Haggis Brera Tech. But I have worked on similar machines.
*** You should contact your vendor for service. The following is for information only. ****
* I believe this is a multiple selection machine. Meaning there is several selection buttons that can be pushed for the desired dose of coffee. Most of the machines of this type require a dose calibration for each selection. Check your manual for the selection on the "Long" dose. (FYI long is usually 1-1/2 oz dose compared to the standard 1 oz shot. Check the internet on how to make an Americano with this machine. It's usually 1 shot of espresso with hot water added to fill the rest of the mug.)
* you may also get help on you tube for this machine as lots of people have come across this machine.

If you have that spider fuel system, I always check that first. That system is noted for problems. Use a gage and check proper fuel pressure, 60--66 psi. After you get it started, It should run with less pressure.
How long since over-all tune-up? Any applicable trouble codes?
* You will need to program groups again.
* I'm surprised I did not record and upload a programing video *sigh*
Oh well, somebody did it already:(check at 3:57 on the following vid) https://www.youtube.com/watch?v=0-3SbS-PU4Y
* Set up each shot with a filled portafilter (for the appropriate dose setting. Single for single, double for double, etc.)
* Press and hold "Stop" button till it light (and/or beeps). Release stop button
* press and HOLD the appropriate dose button (within 5 seconds or it cancels out)
* Watch the coffee dose as it pours out into cup or a shot glass (for accuracy)
* Release the dose button just before it hits the desired amount. You may have to do this several times to practice.
* Continue with setting the dose on the other settings (long, double, etc.)
* Note; you can set the "least used group" as in a 3 or 4 group head machine with specialty doses. Like a triple if you have the proper portafilter for this shot. Or an "American" long shot (though I don't recommend running 6-8 oz of water through a single coffee dose. Though I have found some shops using drip coffee through a triple basket and very long dose to fill mugs. They didn't want to get a regular 12 cup brewer.)
* There are other dosing tricks like copy over to other groups. But I've found that setting each group and dose is good practice. (and I have to do it several times a day as a Espresso Tech.)

The factory setting should be 8. The higher numbers are finer. The + and - knob is the doser amount, the amount of coffee in a shot dose. Average is 7 gm, the middle. The highest is 14, I think. Generally, the highest dose shouldn't be used consistently because it can cause stress on the brew group. Just brew two shots.
I have a 1999 Ram B 1500 Van, auto transmission, 5.9 L engine.
Same problem, trans hesitates in 2-3 upshift, sometimes 1-2
to 2-3 upshift. Posts trouble code P1756 - Transmission Govenor pressure too low at below 15 to 20 Psi. Transmission pump shot or valve body leak stops trans from reaching proper pressure to shift, which is minimum 15 Psi.
Either trans is leaking in valve body, valve is stuck, shift solenoid on valve body is sticking, or pump is shot.
