    throwing that code due to the tc not locking up properly as it's a 13 pin box with a 12 pin harness and pcm.

    now for the dodgy repair,

    1870 Fix - 4L60E "TCC Mod" 95/6 -> 94 also fixes P1870 - Chevrolet Impala SS Forum : Chevy Impala SS Forums

    97 4L60E bolt directly into a 95 car? - LS1TECH post #3 has images of where to mod
    also replace the 3-2 control solenoid and internal wiring harness (or bend the pins on the solenoid) and it'll work normal and stop throwing the code

    using a set of car ramps and give the trans a service (drain, new filter and fluid) and while you're doing that with the pan off tackle the fix, it shouldn't take more than an extra 20 mins if you're reasonably mechanically minded..
