Question
Hi, I have had my check engine light on for about a month or so now. When it first came on I took it to Autozone where they do free diagnostics. The code came up P1870, which reads transmission component slipping. I immediately took it and got the transmission fluid flushed out and the light stayed on. The car is driving completely normal and I feel nothing wrong with the way the transmission is working. I got the fluid flushed at Jiffy Lube and they told me that they do not replace the filters that they just flush it and that cleans the filter. I am taking it to Ragsdale in a couple of weeks, but do you have any idea what this might be or how much it might cost me? I don't want to have to trade my car in. :(

Hi well the code is right -component slipping P1870
If the light is still on- it might just be a small thing or a weak spring or in the valve body.  as the light on the dash can even come on with some cars if the gas cap is too loose. so  it might just be a small thing or just a adj.
