Hey guys,

Was driving my Impala not more than 20 minutes and my Check Engine Light came on. Took it to AutoZone and got a P1870 (Manfacurer Control. Trnsmission).
Does this mean my Transmission is going out? Do I need to rebuild it or get another? Haven't hecked my fluid yet but the transmission over the past week seems to e slipping at tad bit.

2000 Chevrolet Impala 3.8L
Mileage: 148,000

 

I always come back for help here but NEVER get replies to my questions so I always have to take it myself to the dealer to find an answer. Why create a forum for this stuff when there is no one to help.

 

So did the dealership want to replace the transmission? Did they change the fluid and filter for a complete service? I don't think that the slipping and error code means that the transmissions needs to be replaced but without more into it is hard to make a judgement. Is the fluid dark or smell burnt?

 

i looked up that code.
has to do with the PCM detecting slipping.
It may also have to do with the valve body- Ive heard there was a redesign of the valve body.
Do a search online for the code- theres alot of info on it.
