Shifting problem with Volvo

I have 2007 780 volvo
I'm having same problem I clean everything couple of months ago then is was perfect but now same problem
So did you get fixed please let me know would really appreciate

 

i have the same issue. mine started doing this after i took the batteries out and replaced the middle air tank. now the tranny won't go into high gear and the air bags don't inflate

 

Need help with my d12d automatic gearbox.
The truck can start in R, N, A and M.
In short it starts in any gear.
What can be the problem.

 

I just posted a similar problem. The replies give me things to check.

 

So did any of you get the problem fixed? What was done to fix it?

 

Truck just died at the light rt 30e /205 towed it lets see whats wrong,im getting these codes 2008 d12 ultrashift

 

I started checking electrical connections for thetransmission. I eventually found frosty connections for theshifter pod behind the drivers seat. Clean and light lube with dielectric grease. I found water under the mat on drivers side, possibly from door weatherstripping that was not secure.Perhaps moisture relates to frosty connections... Severalthousand miles later problem has not reoccurred.

 

Truck worked fine after sitting overnight,but i insisted on replacing range splitter and after testing it showed that it was bad,strange how mechanic said he could not see stored codes
