VR auto no 1st or 4th

[VN Commy]

Hey guys,

My VR auto has been unable to shift into gears 1 and 4. The wiki page for the 4L60E transmission (this is what the VR uses, right?) says the 1-2 shift solenoid is on for both these shifts so I assumed it was faulty. An 82 diagnostics error code (1-2 Shift Solenoid “A” Fault) seemed to confirm my assumption. After buying a new solenoid and installing it with new filter and ATF I was surprised to find the problem was not solved and the code 82 returned after an ECU reset. Can anyone confirm that the passenger side solenoid (of a right hand drive holden) is indeed the 1-2 (and drivers side the 2-3)?

Any other ideas on what could be wrong if I did change the correct solenoid? Yeah, I should have done them both but parts are expensive over here.. :| Holden wanted to sell me one for $250!

did the one you replace have the valve with a spring pushing it against the solenoid?
If it did then you replaced the correct one otherwise you have replaced the 2-3 solenoid instead

are the v6 auto solenoids the same as v8 auto solenoids?

 

[Trikky]

yep they are the same, also 1-2 and 2-3 are the same

Looking at the diagram below, the solenoid nearest the control valve body (big round looking thing at the back) is the 2-3 shift solenoid. The other one is the 1-2 shift solenoid. If you replaced the passenger side one, you replaced the wrong one.

Thanks for the help.

I replaced the drivers side solenoid today but still get a code 82 and no 1st or 4th. Any ideas what could fix it?

Is it common for the ECU to not send the signal to the solenoid or is it more likely a dodgy connection somewhere? What path does the wiring take to the transmission and where are the best places to check? Thanks in advance.

Check/replace fuse F12 in the main fuse panel assembly (behind cover on lower RHS of instrument panel).

Fuse F12 was still good. Are there some wires I can test to see if the fault is in the trans or the ECU?

 

[Trikky]

cannot say I have heard of an ECU causing this fault, when you replaced the solenoid did the clip on the plug break at all?
I would most likely suspect that you have an issue with the wiring in the auto as it gets effected by the heat etc and becomes very brittle
