Express 1/2 Ton Van V8-5.7L VIN R (1999)
After the test has run, the Tech 2 will display one of these screens.
Vehicles with a "test passed" result should experience an engine sag, stumble, or stall, this is due to the Tech 2 applying both TCC solenoids to full
capacity during the test. Vehicles with a "test failed" result should not experience an engine sag, stumble or stall. A "Test Failed" result would indicate
that there is most likely an internal transmission condition related to items that could cause a DTC P1870 to set. An indeterminate test would result in a
vehicle retest request.
Important:
If the vehicle has passed an initial test, but the vehicle is suspected to have an intermittent or indeterminate condition, it is recommended that the test
be run multiple times at higher transmission temperatures. Running this test multiple times will help technicians duplicate an intermittent DTC
P1870.
