Warning lights

[250FRajcic]

a couple of days ago my engine check light and my check trans light came on at about the same time. Any ideas of what could be wrong? or is this just a mileage related issue where i should check both anyway? i have about 109,000 on it.

This is some of what the '99 VX repair manual says about the P1870 code-

The PCM monitors the difference in engine speed and transmission output speed. In D3 drive range with the TCC engaged, the engine speed should closely match transmission output speed. This DTC detects excessive TCC slip when the TCC is engaged. This is a type "B" DTC.

-Range switch malfunction could set a DTC P1870.
-A mechanical failure of the shift solenoids, TCC solenoid, or TCC PWM solenoid could set a DTC P1870.
-Internal transmission failures may set a DTC P1870.
-An intermittent or incorrect engine speed signal may set a DTC P1870.

The PCM will turn off the CEL and CTL after three consecutive ignition cycles without a failure reported.

There is a TSB for DTC P1870-
