Transmission i have a 97 cadillac catera and i wan to know how to put the transmission oil in and stop it from leaking

You need to have your valve cover gasket replaced.

Your Catera has a sealed for life transmission so therefore on one of these models there is no dipstick and you cannot check the fluid level yourself. The dealer can check the level but that is only necessary if you have a leak. Use a premium grade oil and a quality filter such as AC/Delco, Wix, Purolator, or Bosch. The correct weight oil is listed in your owner's manual and possibly on the oil fill cap or dipstick.

The cats use hydraulic lifters. Just before your next oil change, or when you are down about a litre of oil, put a litre of transmission fluid (Dextron II) into the engine and drive it about 2to 300 miles and then change the oil and filter. You should hear the valve train noise dissappear within the 1st 20 or 30 miles.

Do not overfill!!!!!

This is assuming you have a plugged hydraulic lifter(s). If you have a worn cam or worn valve train, you need to remove the heads (both) and send them to a machine shop that does heads and re-install...new head gaskets, valve cover gaskets as well as any worn cams. valves etc....

Car really has to be worth it. At this point, if you love Cateras (I have 2 2001's), I would sell it the way it is and get a 00' or an 01'.

The 97' and 98's are not worth the trouble.......

Is it Oil,or Automatic transmission fluid?
I've changed several Catera Radiator's because the transmission cooler cracked inside of them!!
Better check the transmission fluid for engine coolant too,Coolant in the Automatic Transmission will kill it purdy Quick!

You will need a set of these...but just the smaller ones..thats for the oil drain plug..Now for the oil filter, you may need an oil filter wrench to take it off.Image Not Available

You might as well stop looking for a transmission fluid dipstick. Your Cadillac,like many newer vehicles, does not have one. Instead, there is a fluid levelinspection port, that in your case, is in the oil pan of the transmission. To correctly check the fluid level requires the engine to be running with the transmission at operating temperature, about a 15 mile drive. In addition, the vehicle has to be level. You can jack the vehicle up evenly on both ends, but a lift is the preferred way. The fluid should be even with the bottom of the threaded openingin the transmission pan when the plug is removed. A quart of tranny fluid with a screw on nozzle will help you add fluid as needed until it slightly flows back out of the threaded plug hole. Recheck the plug for any leaking of tranny fluid once you have completed adding fluid and reinstalled the inspection plug.

I haven't changed the fluid in a Catera, but all the auto trans cars I have, it's added through the dip stick tube.

try using a thicker oil like a 10 w40

alarm has set itself have to disarm it

First of all ensure that your car is leaking coolant fluid, and what is dripping is not just water condensation from the air conditioner.
If you have a coolant liquid leak, it can be from one of the ducts leading to radiator , from water pump or radiator itself. Check liquid levels, and if you have a leak have the car inspected by a qualified mechanic.
A broken water pump, for example, can cause your motor to blow in few miles.
