Frequently Asked Questions

What solenoid fits a Case 850H dozer transmission?

The transmission control valve solenoid matching Case number 349296A1 fits the 850H along with the 550E, 550G, 550H, 650G, 650H, 750H, and 1150H. Confirm your machine serial number and existing part number before ordering.

What are the signs of a bad transmission control solenoid on a Case dozer?

Common symptoms include erratic or delayed shifting, loss of forward or reverse, and gears that stick or fail to engage. A failed control valve solenoid can cause these issues. Matching the correct replacement part helps restore proper shift control.

Does this solenoid fit both the 550H and 650H dozers?

Yes, the control valve solenoid covers the 550H and 650H as well as several other Case dozer models. Because coverage spans multiple generations, verify the part number on your unit. Call the parts team at (800) 909-7060 if you need help confirming fitment.

Can I replace just the solenoid instead of the whole valve?

In many cases the transmission control valve solenoid is serviced as its own component. We carry the solenoid to match Case number 349296A1 for these dozer models. Match your existing part number to be sure it is the correct assembly for your machine.
