Leaking Transmission Fluid

Asked by Nov 06, 2012 at 02:19 PM about the 2004 Kia Spectra Base

Question type: Maintenance & Repair

I can see I am leaking transmission fluid (redish liquid) yet the transmission fluid level remains "full"?  I
had the transmission pan replaced a month ago. The check engine light is on (but in no relation to the
transmission fluid) with the following codes:
P0030 (H02S heater control circuit (bank 1 sensor 1)
P0134 (02 circuit no activity detected (bank 1 sensor 1)
P0121 Throttle/Pedal Position Sensor A Circuit Range/Performance
The car was recently at the dealership replacing the 02 Sensor and cat converter and I still get these
codes?  I have lost faith in going to the dealership.  I've continued to drive and the car runs well but
obviously if transmission fluid is leaking something is drastically wrong.  Please help!

P.S its an automatic


Leak more than likely from transmission pan gasket . they did not tied it or bad gasket.. need to be replace. After replacing the 02 Sensor and cat converter should be no P0030 and P0134 codes.


If you have power steering, Check the power steering fluid level. Some power steering fluids are also red.
