Ford focus transmission starts slipping on od auto. 2003 ford focus 2.o litter 78,K miles is this normal failure on this type of vehicle?

have you told any of the tranny places of problem when they were replacing or working on vehicle ---has the tcm been tested ---and scan for any trouble codes

I would suspect the VSS - vehicle speed sensor is going bad . The C.C. to work needs a speed input an the shift points are also speed related ,plus some other thing's . To know for sure a qualified tech should hook of a factory or some other type professional scantool that can view sensor data parameters ,while driving the vehicle . Not auto zone scan .

Possible low fluid level causing the fluid to aerate. Check fluid level with vehicle running on level surface and add as required

replace clutch disc.

Transmission gear assembly and transmission needs inspection. Also check the transmission fluid level. Also is the fluid getting leaked or its low.

Transmission is slipping, It will have to be rebuilt

well,whoever did the transmission needs to look at it again.It sounds like a solenoid problem internally in the transmission.or a plug,wiring,or vacuum leak

there inside the tranny you have to remove the pan to see them but thats not going to be your problem go buy a can of TRANSX first!! and try that if that helps then you need to plan on rebuilding your tranny or replacing it

the OD light is flashing to let u know a fault has occurred in the transmission electronic controls or that it is slipping plus other issues, go to Kragen or Autozone and ask them to run a trouble code test, it is free, post the code back here for me to look at.
