Volvo only engages ODD GEARS..EVEN GEARS feels like NEUTRAL

Yes Guys
I will be driving BOBTAIL or a EMPTY FLATBED to get something on my way back.
I drove yesterday to HOME TERMINAL in 11th....cruise around 53/54 mph

Will probably drive through Sunday night

 

@77fib77 ...Prime?

 

Ok
As i said earlier the Air leak from 1st Tank ( out of 3) and the gear issue started simultaneously.

When driving ODD gears the air was building and leaking all along.

Now fixed the AIR LEAK and it stopped taking the EVEN gears too

 

I have the MANUAL OPTION but i drove it in AUTO MODE....somehow the truck has learned to skip the EVEN and keep itself in ODD gears

 

They have NARROWED it down to FORK HOUSING

 

Thanks
Yes it was FORK CONTROL HOUSING
All good now
Also changed CLUTCH/ACTUATOR/REAR MAIN SEAL/ SELENOID/small AIR LINE/PILOT BEARING....as we had to take down transmission
