Just for clarification in case anyone else needs the part,
the output speed sensor on the transmission is part #4799061AB.

 

did you change the part and fixed your problem?

 

Not yet - just ordered it this morning from a dealer down south - the dealer by me wanted double for it - getting the sensor for $28. I'll have it on Monday and get it done next week.

 

Problem solved! Changing both was the way to go.
Thanks again for all your help!

 

OK so about 2 weeks goes by with no lights coming on. Everything seems normal since changing the sensors, but now I have the ABS and Brake lights coming on. Sometimes they stay on together, sometimes its just the ABS light that stays and sometimes nothing. WTF? Does it sound like I need to replace the ABS Control Module?

 

It could be possible one of the sensors your replaced may be faulty. I look there first before digging into your ABS system.

Also, did you change your axle fluids as well as tranny fluids? It may be possible there may be comtaminants in the fluid wreaking havoc with the sensors.
