Hi all,

 

I have the auto 3.0 v6 300zx 2+2 sports.

The problem i'm getting is it's not going into gear and i am having to click the hold button to make it change up.

Also it revs for no reason and the a/c and radio come on intermittently when going along.

 

Have had gear box recon; brand new internals and auto cooler

Throttle sensor done.

 

Been checked by auto electrician's;

Ztec uk Consult check, plus setup and crank angle sensor, tp sensor diagnostic

Autoelctix's unable to trace fault (tps checked, potentiometer and assorted wiring)

Fishbrothers; diagnostics, suspect either ecm or wiring fault

can not find prob

the gear box not talking to auto check do not know the term for this

the problem seems electrical but can not locate.

was going to try the wire looms but very pricey.

 

Any idea's?

When you had the throttle sensor replaced did they get the voltage right?

 

You have to loosen the screws and twist it to the right reading otherwise it causes all sorts of problems with the autobox changing to early and refusing to change gear etc.

 

I had exactly the same problem with my old TT auto

 

EDIT: looking at it if they did a conzult check they should have set the voltage correctly at the time hmmmm

 

Sounds like it could be the gearbox ecu could be at fault/wrong connections when the gearbox was re-built?

 

Did everything work before the bearbox was refurbished?

hi

thanks for reply

had gear box replaced when all other work had been done as

i was assured that it must be the problem/

spent 3000 thousand so far!

Do not no where to go next.

it was just the gears before the summer

now sorts probs with electrics.

had to disconnect the sound on alarm as that keep going off as well

as it is an intermittent fault do not know

and as the prob has got worse there must be some thing that connects

all these problems together?
