Another Noob need help. Transmission Controller


electronic transmission controller mercedes/chrysler/jeep. 722.6  5 speed

hi guys, huge fan of arduino , big day dreamer tired of day dreaming, bought mega 2560 bring dreams reality.

problem i've never programmed before.
did electronics/mechanical engineering in school before arduinos.

if topic has been covered before , can pointed right direction appreciate it.
i have 5 speed automatic transmission i'd control possible paddle shift mode.

it has total of 6 solenoids.
3 solenoids shift 1st 5th , 1st (1st-2nd/4th-5th uses same solenoid)
#4 solenoid torque converter clutch
#5 solenoid modulated pressure control
#6 solenoid shift pressure control
(solenoids here not in articular order)

i have played around with sketches , has basic understanding on i'm still learning other language aspect of sketches.

the shift pattern of transmission follows


gear                                | 40% duty cycle| 33%duty cycle
shifts | 1-2/4-4 | 2-3 | 3-4 | mod pc #5      | shift pc #6   | tcc |
 1st   ---   off  -- off - off  - pwm                off                 off
---------------------------------------------------------------------------------------------------------
shift ---   on   -- off - off  - pwm                pwm              off
--------------------------------------------------------------------------- ------------------------------
 2nd  ---   off   -- off - off  - pwm               off                pwm
----------------------------------------------------------------------------------------------------------
shift ---  off   --  on - off  - pwm                pwm               pwm
-----------------------------------------------------------------------------------------------------------
 3rd  ---   off  --  off - off  - pwm                off                pwm
-------------------------------------------------------------------------------------------------------------
shift ---  off  --  off -  on  - pwm                pwm               pwm
------------------------------------------------------------------------------------------------------------
 4th  ---  off  --   off - off  - pwm                off                pwm
-------------------------------------------------------------------------------------------------------------
shift ---  on  --  off  -  off - pwm                pwm               pwm
--------------------------------------------------------------------------------------------------------------
5th   ---  off  --  off  - off  - pwm               off                 pwm


i known on engineer things. did make complicated?

any input appreciated. thanks.

time start daydreaming , determine current necessary operate each solenoid. same type? have 1 wire , use transmission/engine other part of circuit, or have 2 wires?

does computer control system on car care if transmission solenoids disconnected? engine speed during down-shift operation?

so, guess not making complicated enough!
