There is a round plastic container near the left hand side between engine and mud guard. Unscrew the top and you will find a dipstick that shows correct fluid level. Use transmission oil sold at garages etc. The brake fluid container is on the same side near the radiator.

You will need to take it to somebody that has a scan tool or a OBD 2 or better scanner. I think ammco, kragen, or autozone will hook up a scan tool and turn it off for free. check it out

Hi, you dont say how much oil is in the body but if its a high miler some residue is normal as it seems to make its way up via the vent tube.This can be cleaned out with a good throttle body cleaner. But remove the body from the intake system first as you dont want to dose the engine with this stuff as it will cause the engine to over run if too much is fed into the intake. Let it dry out before re starting the car. Be carefull.

Sounds like you have problems with a part called the valve body inside the transmission or other hydraulic control problems, i suspect you will need to overhaul the transmission to cure this.

You could have air in the clutch cylinder or there could be wear in your clutch master cylinder, You need to start by checking the fluid the the reservoir and then try bleeding the clutch, if this doesn't help then you will need a repalkcement master cylinder, It is recommended that you replace the slave cylinder at the same time as well as the flexible rubber hose.
