Lockup Control I would like to add a switch* to my shifter handle that
will control lockup. I can envision it being pretty simple
(SPDT, center-off would let me force lock, force unlock
and let PCM control (Gnd, open, RED pin 42).
*or something more elaborate, controlled by one switch
Behind that, I have the notion to make some logic using
the 1-2 and 2-3 valve controls that would keep the TCC
from locking up when the gear selector is in D (only in
OD, making D a sorta-sport-mode). Probably series relay
logic with the TCC PCM output, using 12V reed relays.
Lastly, I would like to get the TCC to use 100% duty
cycle. I think slippage is the result of it *****-footing
the PWM and I want the TCC to hold hard under load.
Questions - can the TCC take a DC 12V (or whatever)
continuous? how bad would the apply shock be if the
PWM was 0-100% instead of ramped? Wondering if
just cutting the TCC PWM wire (RED 2) and tying TCC
PWM pin to (+12V)? would hurt the guts, or set fault
codes?
