aw4 only manual shift


Recommended Posts

  • 2 weeks later...

update now...  been busy ... then recovering...  Lift repair (replace 20 y.o. hydraulic hoses)

it's been years since i have been up and down a 12ft ladder so much....

 

so today I replaced the Neutral Safety Switch on the AW4,  with lift it was not "too" bad of a job.

 

Mixed results...  I do NOW have reverse lights, and no-start in 'gears', and start only in N or P ( did not have reverse lights initially):banana:

 

but..........  made zero difference in transmission  :confused::(

"still" tries to start in probably 3rd gear with selector in D,  and when i manually shift to 1, i get 1

 

was tired so walked away from it.  I think next is to go back a few posts and

 

Key ON  C234 not connected to TCU

Gearshift  "1" position

c234 D7-C8  voltage?

Gearshift  "D" position

C234 D7-C9   voltage?

 

tired today... will drop lower dash again tomorrow and test unless something else is suggested...

 i have since also installed new positive and negative battery leads and cleaned grounds.

True.

 

 

 

 

 

Seems like NSS needs some looking at.
