PSI and BAR Pressure Units
« on: July 18, 2015, 12:44:08 »
If I am wrong, please correct me, but this is what I came across: in quite a few places the manuals/posts say that the pressure in automatic gearbox at idle/fast idle with vacuum disconnected should be around 4 bar. In others around 40 psi.

I think the correct values are (please correct me if I am wrong!!!):
At solenoid center position, vacuum disconnected it should be 41.24psi or 2,9 kp/cm2 or 2,84bar
For kick down 65.41psi or 4,6 kp/cm2 or 4,5bar

The kp/cm2 values are from German BBB 27- 0/3 - I hope I read them correct.

I thought maybe it is useful to clean up the units a bit.
