Hi there,

I done a transfer case oil change recently after having vibration in issues, changing fluid didnt solve the vibrations so i installed ista and done a vtg calibration which took 2-3seconds and gave a message saying the readings where 0.4 in difference compared to old values,

Vibration is still there, only happens at very low speed 10-15mph.

My question is: does vtg calibration complete in a few seconds? Or ista made it look like it was calibrated but it actually wasnt?

And also what does a vtg calibration do?
Does it need to be done after changing tyres?

Thanks
