If its for the transmission you have to check it while he car is running...if its for the oil you have to go it without it running and if its over the full mark on the oil you will need to drain some of it

Hello, I had replaced my transmission, But when i started slowing down just before i stop it would slam down into the gears


I take it you have an auto box? Have you checked the fluid level after driving for 20 mins to get the correct hot temp needed to check the box level marked hot on the dipstick.Do not use the cold level as this is the wrong way to check

IF the oil level is above the hot oil mark when cold then your problem is frothing of the oil from excessive oil . This causes a loss of pressure in the gearbox pump and the pressure is not there to activate the clutches and bands. Correct the oil level to where it should be and if the problem persists have a pressure test done on the gear box.

I HAVE A WARNING LIGHT ICON ON AT THE BOTTOM LEFT OF MY DASHBOARD IT LOOKS LIKE A CROWN OR A CIRCLE WITH SPACES IN BETWEEN. THE COLOR OF THE ICON IS ORANGE. ITS A LEXUS 1990 LS 400


I believe what this symbol is the radiator. It comes on when the coolant level is low. Take a look at your radiator coolant level and if low add some to the full mark. Do this when the engine is cold to avoid getting burned from hot water and steam.

My lexus ls400 was running hot and will not start


Check the oil for coolant cross mix (milky color on the lower part of the dip stick.
If your cengine has over 140,000 miles then it can be a blowing head gasket.
The only way to check it is via cooling system pressure test or dye test.

How do you check the auto trans fluid in 1995 ranger xlt 3.0l?


There are two's to check.
1st way is to check it when the reansmission is still cold, whild the engine is running and it's in park. Pull out the dip stick to the transmission which should have a red handle. Pull it out and clean it and push it back in and pull it out again, at the end of the dip stick there are markings which should say cold and hot. If your transmission is still cold do to your just started it. The oil level should at least be in the cold markings or just above. 
2nd way is the same as the first, just your transmission has been working. Say you have been driving and stop for gas and everything is hot and you check your transmission oil. The you'ld look to see if your transmission oil is up to the full mark where it say's hot. 
Note: It's better to check the fuild to the trasmission when it's hot, just becareful not to burn your self.
Check for oil level and texture of the oil. Oil should be free of bubbles and have a bright red in colour. If there are sign's of bubbles in the oil or the fuild is dark burgundy colour. it's time for a tansmission oil and filter change. Try not to do a transmission flush if you have over 80,000 miles. 
Good luck and hope this helps
