Gearbox Oil

[Spirited]

Hi Guys,

I have just changed my gearbox oil and I now have a check engine light?

There was no check engine light previously before the transmission oil change, and I have refilled it to exactly 1.9L as specidied in the owners manual for manual 1ZZFE Corollas.

Must I reset the ECU? Add more fluid? I just can't understand what it could be?

There are no leaks and exactly 1.9L of Castrol Syntrax 75-90 Oil was put in, although 2L came out?

Please point me in the right direction, I have searched and am not sure which way to go.

Greatful for any input.

Sam.

is there a sensor that is sticking from the gearbox?

maybe the cable is loose, or the connections is not seated properly?

Tried checking the computer for what error code it's throwing out? That's usually the reason behind a CEL (Check Engine Light) being displayed.

Also, you shouldn't fill gearboxes with specific amounts of fluid - they're there only as a guidline. You fill the box until the fluid level reaches the fill-plug.

Hello,

I haven't checked the error code output as I don't have a OBDII or other required things to read it. Thankyou for the info regarding the level of the fluid in the gearbox, I will look more closely at it today.

Problem resolved. Engine check light came on due to me leaving a sensor unplugged near the throttle body when removing the filler bolt.

Thanks for the assistance.
