I just notice check engine light have kinda noticed at 55 will shift slightly diffrent . Is this an expencive proublem?
The code is for a faulty shift solenoid. A good transmission shop can give a price to fix this.
If the transmission is shifting differently, you may want to consult a transmission repair shop. They will tell you how much.
SOURCE: transmission
I recently ran into this same problem. My truck has 125,000 miles. The service engine light would come on from time to time. I did as you and got a P1870 code.
P1870
The transmission is in 4th gear with the TCC (torque converter clutch) engaged and the ECM has detected excessive slippage when comparing the input shaft speed to the output shaft speed.
Probable causes
In my particular case a fluid and filter change solved the problem. I do plan on dropping by the trans shop and let them do a complete service in the near future. (Fluid, filter, band adjust, and check pressure)
Good Luck.

The codes stored in the engine computer are needed to further diagnose this problem. To check the codes, go here!
Retrieve the codes in terminal A2. (and A6 if you have a non-turbo)
List the codes here and I can assist you further.

do the pin point tests, these start witjh running a trouble code test, autozone and kragen will do this for free, if u haven't had the trans apart then cross out any crossed wiring issues, but I do think you will find a problem with the 2-3 shift solenoid, either the solenoid has failed or the connector has a problem on the outside of the trans.

crank shaft sen. is easy enough to change.its mounted near timing chain cover,cam sen.is somewhat harder,its in the distributor,id doubt that both are defect
SOURCE: how do you reset the check engine light in a 2001
Reset the ECU / PCM for Check Engine light removing the neg battery cable for 5 minutes to reset the codes. If the warnin glight come on again, I suggest scanning you vehicle for details, one fault is in there.
Good luck (remember rated this help).
