In a '89 Chevy Beretta the trans axle fluid is more of an oil and can be purshase at a local dealer. Its a 60 wt. synthetic oil. The fill tube is located between the motor and firewall,just under steering column at trans axle housing towards bottom of motor. It requires a funnle with a long flexable tube.
Edit by Loosenut: If its a stick use Styncromesh 89/90 if its automatic use Dextron III
At the tip of the axle that goes into the transmission is a snap ring. Make sure this clip has the open end pointing down or you will have problems with insertion.
i would check the vacuum hose that goes to the vacuum modulator on the transmission the vacuum modulator probably has a hole in it and the fluid is going into the engine and being burned or check your coolant the radiator may have a hole in the transmission cooler inside the radiator so check your coolant and the vacuum hose for trans fluid good luck

It is on the back of the trans, where the passenger side axle goes in.
Back of the trans, in the housing that the passenger axle goes into.
the trans fluid on a auto trans goes through a tube in the radiator to cool the fluid if the tube has holes in it, it will leak trans fluid in to radiator. you need to replace radiator or have rebuilt.or you could put on a aux trans cooler and put plugs where the trans lines used to go.
Normally no, but It is possible, Top the fluid level off, an see if the problem goes away.
Be very careful NOT to put trans fluid in an engine ! - It goes down the tube that holds trans dipstick, into the transmission.
