What temp should transmission fluid be?

What temp should transmission fluid be?

between 175 and 225 degrees
According to TCI, the ideal operating temperature for automatic transmission fluid is between 175 and 225 degrees. At approximately 240 degrees, important additives in automatic transmission fluid (ATF) begin to cook.

What type fuel can be substituted for an aircraft if the recommended octane is not available?

What type fuel can be substituted for an aircraft if the recommended octane is not available? The next higher octane aviation gas.

What should the pressure be on a D8N transmission?

380 at low idle is ok, pump may be worn some. 430 at high idle is ok, a little low. Pump wear would show more from cold to hot oil. Cold pressure is higher and hot will be lower. This is ok, but further testing is needed to determine where you have problems.

Why is my D8N transmission not moving at low idle?

Pump pressure is too low at low idle. This could be from a restriction in the filter or strainer. Make sure filter is new and does not have metal in it. Remove main strainer with magnets and see how much metal is on it. If these are clean, the pump is worn out and should be repaired or replaced. Low pump pressure would cause low priority pressure.

Where is the priority valve on a D8N?

Priority valve is in the supply manifold seen at the rear cover, all other settings are inside the transmission control valve. catmastertech and 87 other Heavy Equipment Specialists are ready to help you

What should the oil temp be on a Duramax?

This is with a huge Killerbee oil cooler. Modern oil does get it’s life cut down 50% by high, 300 degree, temps. No oil company is going to give you their results and the transmission temp failure chart is there to sell coolers. You will have a small heart attack when you get the “Low oil pressure stop engine” DIC on a Duramax.

380 at low idle is ok, pump may be worn some. 430 at high idle is ok, a little low. Pump wear would show more from cold to hot oil. Cold pressure is higher and hot will be lower. This is ok, but further testing is needed to determine where you have problems.

What is the B & m transmission oil temperature gauge?

Printed in U.S.A.9500048-08 Your new B&M transmission oil temperature gauge will accurately monitor transmission oil temperature and warn you before excessive heat ruins transmission fluid or causes damage. High heat conditions are destructive of both transmission friction materials and transmission compo- nents.
