Hi, The main problem is an high pressure on the hydraulic system. After satarting the engine, the transmission oil filter case jump out due to high pressure on the hydraulic, without any movement of the machine.

Thanks.

Are you saying the top of the transmission filter lifts up and oil flows out when you start the engine.

Are the bolts stripped out. Check the threads in the trans filter housing. You may have to helicoil the filter housing. While you're working on the trans filters, you should pull your magnetic screen and clean it. If your filters have not been changed in a while, now would be a good time to do this as well. How much iron has been captured by the screen. Are your filters in tact or collapsed. Save the old filters so they can be examined for transmission material.

If your magnetic screen is fine and your filter housing is not stripped, come back for more info.

What have you checked?
Have you looked for any crimped lines or hoses or signs of blockage?

Mike,

No, I am saying housing down when pressure is high of the Transmission filter (No, Magnetic Screen) when engine start.

The Magnetic Screen is clean.

Old Magnet,

Yes , I checked are ok

The filter housing is normally a one piece unit with removable lid.
Are you saying the housing is separated or damaged?

I am not sure what your problem is from your description. Please describe your problem in more detail.

If you have a Torque Converter failure, it would force oil out of many places. If the relief valve on the filter housing head failed you will hear a whining sound. If your transmission filters are installed improperly, the filters will move around. Is the spring intact. Is the spacer installed between the filters.

Your transmission filter is not part of the main hydraulic system. It delivers oil to a separate transmission hydraulic pump. If you have a high pressure problem not related to the Converter, there are lots of other things to look at once I have a better idea of your problem.

Any chance you can post a picture of the problem area.

Here is the Hydraulic Schematic.....there is only one main pump and a combination scavange and recirc pump.

The filter housing has a differential pressure relief valve set at 25 psi.

Main pump hydraulic pressure is approx. 415 psi so it would seem very unlikely that hydraulic pressure would fracture the filter housing. If the pump/filter discharge became blocked pressure could get pretty high as there is no relief at that point.

Agree there is not a lot of info to go on.
If the filter housing is busted I'd be suspect of physical damage, not hydraulic. At least at this time.

Old Magnet,

I found separated.
