that in USA is called OBD2, federal codes, P0 = fed
P07xx is transmission error specific
rpm MEANS ( GAUGE OR ENGINE RPM OR BOTH DO THAT)
SURE IT SHIFTS WRONG AFTER ALL THE TCM BRAIN IS BEING LIED TO.!!! ,,,,, 100% expected.
so no other DTC stored or shows up in Pending (a button)
to work on any car your self we first must know 2 things
what engine is there (size) and what transmission is there.
in fact they match up, by engine max torque spec.
also tell your country and cars are not the same all over earth
the shop manual (real) states P0715 is fix first DTC error and is true,
from the list. of all those.
input speed sensor
let me find this sensor on the box.
Sensor assembly - transmission turbine shaft speed (TSS)
there it is, replace it, if still fails ,do all transmission tests in the shop manual
this is the main pump cover and I think what this is
is pump speed, or TC input speed to box,
even the wire fell off or is rusty or looks bad.?????? looking is first.
