140h transmission issues

[Crunch1125@]

I have a cat 140h grader. First gear works every time. And 5 and 8 gear work most of the time. But sometimes you have to switch back to park and then to 5 or 8 for them to work. 2 gear bumps then goes to neautral most of the time. Sometimes nothing at all happens. But never works. I’ve swiped 2 and 8 solenoid around. And that didn’t do anything

I’ve swiped 2 and 8 solenoid around.

Swapped just the solenoids or the complete modulating valve assemblies.?

Got a machine Serial Number.?

Have you changed the oil and inspected the transmission suction screen recently.?

Do you have a diagram on where the screen is located ?

Not off-hand. Don't you have the basic Operation & Maintenance Manual for it.?
