I would start with about 3 quarts and run the engine and drive a LITTLE and check the level..and slowly add more fluid to the transmission.
Overfilling can cause excess pressure and blow seals.
How many quarts of transmission fluid does a 2004 Taurus 3.0 OHV require when draining transmission and replacing filter
Aprox 4 1/2 qts.
transmission fluid
The transmission may need to be rebuilt. If it is automatic you can try dropping the transmission oil pan and replacing the filter and fluid.
Your transmission's filter may be clogged, you may be low on transmission fluid, or the transmission may need repair or replacement. If the transmission was full of fluid, I would suggest a transmission flush, or replacing the transmission filter and fluid. If this doesn't help the transmission may actually be damaged and may need repair or replacement.
A filter that filters the transmission fluid.
There is really no way to tell. Take the car to a shop and have them replace the transmission oil filter and fluid. Make sure to tell them you want the filter replaced because some places just suck out the oil and replace it without replacing the filter.
In any automatic transmission the fluid should be changed at the interval specified by the manufacturer. You should have the transmission oil filter replaced also at this time. Many shops will just suck out the old fluid and replace it with new without replacing the oil filter.
Fill the transmission filter with transmission fluid before you put the new transmission filter on. You probably will not need to add any transmission fluid.
Oil filter, yes. Transmission fluid filter, no.
While the original answer below is true, a 1994 Rodeo does have an transmission fluid dipstick. It is right behind the oil dipstick and is where transmission fluid it added. Many vehicles are being manufactured without a transmission dipstick. Transmissions are being held to a quality that has minimized the loss of transmission fluid to the point that manufacturers no longer feel that it is necessary to routinely check the fluid levels. The philosophy has changed. If you follow the manufacturers recommended service schedule the transmission fluid and filter will be serviced before you should need to be concerned about fluid levels. You can change the filter and fluid yourself by dropping the pan, removing and replacing the filter, replacing the pan and adding fluid through the side fill/test hole in the transmission.
6-7qts approx. fill
