There is no dipstick on a '98 Oldsmobile Cutlass, so you must take it to a mechanic and have the transmission serviced after 100,000 miles (per the owner's manual). Poor design if you ask me.
There is a dipstick probably with a red cap on it that pulls out. Have the car on a level surface, engine at operating temperature. Pull stick out wipe it off and look on the stick for possible specifics. It may say "check when hot at idle in park" or " check while hot in neutral". etc. Insert back in and see where level is versus where it should be.
You add fluid at the same place you check it.
Pull out the transmission dipstick (red handle) just as you would for checking the motor oil, but with the engine running and the transmission in neutral or park.
dextron / mercon type 2
Add it the same place you check it, through the dipstick tube. Check the level with the transmission hot, in park, engine running, on level ground. Use only Dexron fluid. Do not overfill!!!!!
I got 2 gallons of transmission fluid... Use one gallon then keep checking the dip stick for the fluid to rise.
about 4 in the trans, about 5 in the lines.
Most likely brake fluid. Check the master cylinder level.
if your standing in front of the car with hood open you will see a t-handle marked transmission that is were you add fluid you will need a funnel to pore it in
And what is an Oldsmobile Sleep? Never heard of that model.
A 1992 Oldsmobile may not shift out of park because the transmission is stuck. Check to transmission fluid to ensure it is at the proper level.
trans fluid goes right in tube used to check fluid level
Check transmission fluid level Try changing transmission fluid and filter
