The SES light came on yesterday, on my daughter's 1997 Chevy S-10 Blazer 4x4.

I drove it over to autozone this morning, listening to the engine and trying to feel for anything that was out of the ordinary... I could tell there was any problems.

When the Autozone guy scanned the code, it came up with (1) code - P1870 - Transmission component slipping (Transmission is in 4th gear with TCC engaged and the ECM has detected excessive slippage when comparing the input shaft speed to the output shaft speed.

Probably cause
1. - Trailer towing may set code
2. - Check transmission fluid
3. - Internal transmission fault.

She had to go to work this morning, so I haven't been able to check the tranny fluid leve... I did ask her if she has been towing anything and she said no... so I am not sure what it could be.

It drives fine... the only thing she did say is that is shook a lil last night when she was sitting at a light, but that only happened once for her.

Any one have any suggestions?
