Case IH Puma 165 X

Hello guys. I have a Case IH Puma 165 x, semi-powershift A1-A6,B1-B6,C1-C6.Tractor bought at 0hrs, now has 1000hrs. From the beginning the transmission jerks especially when downshifting!! 10 days ago I traveled a long road of 40 km and when I changed the gear to slow down the transmission was jerking very loudly with a sound, I thought the transmission was breaking. Now my question is it normal to a semi-ps to do like that? ps. others tractors (powershift) works great smoth change.

The transmission was successfully calibrated several times at the temperature of 60 degrees Celsius but without the desired results.

If bought from new and now with so few hours surely a question for your dealer.
If it calibrated ok it might be the accumulator on the transmission has failed

Accumulator, solenoid, speed sensor or the fact it's a CNH semi powershit

In New Holland language it's termed 'hope and pray command.'

If it were one of these problems, wouldn't it give an error code?

If a sensor or a solenoid was at fault you would probably get an error code and it wouldn't calibrate properly.
If the accumulator had gone you wouldn't get an error code.
Have read in the past that some people calibrate the gearbox 3 or 4 times in a row and this supposedly helps the harsh changes a bit more than just a one off calibration

No not always will an error code be set a solenoid can stick with no error, and a speed sensor can read but not correctly.
This is correct about calibrating more than once, but even better if you have access to dealer level diagnostics or an h menu dongle is to completely erase the calibration memory in the trans controller then recalibrate

You probably won't see a error code on the display if the mid speed sensor is playing up, that would make it rough.

Also, if you had a solenoid breaking down I've had them cause the ECU to forget it's calibration.
