I don't think this is related specifically to the Pioneer. If you read the description it is for an 8 speed transmission not a 6 speed and if I am reading it correctly it is a diagnostic tool (OBD II) for determining what is wrong rather than a delimiter type of protection system.
When operation of a gear engaging mechanism fails in a double-clutch automatic transmission of this type, the large number of electromagnetic valves increases the number of conceivable failure sites and makes it impossible to identify the actual source from among the various possibilities. This has sometimes made it difficult to promptly implement remedial action.
and
Now to explain, reference numeral 1 designates a vehicle, and the vehicle 1 is equipped with an automatic transmission (sometimes called “transmission” hereinafter) T. The transmission T is a double-clutch (twin-clutch) transmission with 8 forward-speed gears and 1 reverse-speed gear and has P, R, N and D ranges, for example.
The description of the assembly/operations also mentions a torque converter, which the Honda automobile DCT has but unfortunately the Pioneer doesn't.
Hydraulic pressure sent to the fifth linear solenoid valve (LSE) 70j is pressure-regulated to control (supply) pressure of the torque converter 12 and outputted from the output port thereof, while hydraulic pressure sent to the sixth linear solenoid valve (LSF) 70k is applied to the spool of the line pressure-regulating valve 70d as a signal pressure, whereby the line pressure output from the output port of the line pressure-regulating valve 70d is pressure-regulated to a line command pressure.
Not to say this couldn't be adapted to the Pioneer. I just don't think that this is anything related to clutch slipping problems that some people are having on the Pioneer.
