1994 Chevy s10 blazer tahoe Lt
 

Hi I'm new here. I have this vehicle that was given to me for transportation. Recently the ABS light came on followed by the speedometer not going over 50 then the trans mission started Erving out with no power. I thought it was the VSS so I had my 17 year old replace it. He also drained the transmission fluid and replaced the filter. The speedometer still stops at 50 Abs light still on and revs out sometimes but not always. I am a female who knows basics, but not an expert by any means. I'm on a limited budget but really need this truck to run any help would be greatly appreciated.

Find the Code first.
 

Try to get the code out. Than can be a Speed sensor problem. Some time ABS light code is for something not directly relate to the ABS unit.
