I have an 88 Ford Taurus L wagon and something like this is happening to me. The transmission is slipping in and out of overdrive and when it does the "check engine" like goes on briefly. I still have to have it looked at so I don't know about the code. But, my car did not just quit working right away. By the way, this problem just started last week and it does appear to be getting worse.
P1870 is Transmission Component Slipping. I have also heard of it referred to as The Code Of Death.
If your transmission is slipping when it is hot that could be a sign that you do not have adequate pressure in the transmission line. It could be because of wear, it's in need of service, or that it's low on fluid.

it starts slipping, highly recommend taking it to Ford service the sooner the better, less damage to the internal parts. Easy transmission for 2nd rate shops to mess up on.
There could be a number of reasons, from low transmission fluid, to a worn clutch, to internal problems. Since i don;t know what you have I would recommend taking it to a reputable service shop and letting them look at it.
you don`t...it is a sealed component that only requires service if there is a leak
P1870 is a transmission slipping code I think P0133 is the left front sensor (drivers side) but i will check on that. For the transmission code the first thing to do is service the transmission and check for debris in the pan....more than a "tablespoon" rebuild the transmission.... according to GM bulletin. Try the service and keep your fingers crossed
Changing the transmission fluid in your LS should be performed by a qualified service technician. There is a fairly comprehensive procedure for servicing the transmission and it requires that the fluid be checked hot and cold. Too much fluid in your transmission will cause it to jerk when putting in and out of gear, the shifts will be choppy and it may even feel like its slipping, and finally there is an overflow valve that will cause the excess transmission fluid to leak out and onto the floor beneath the transmission. A qualified service technician will know how much fluid is enough and how to get it out.
Trouble code P1870 means: Transaxle Component Slipping (4T60-E) Replace the sensor on the transaxle
