What is the code P1870?
What is the code P1870?
Diagnostic trouble code P1870 (Transmission Component Slippage) is a General Motors-specific code whose set parameters are determined by transmission type and engine size. The PCM monitors and compares engine speed to vehicle speed after the converter clutch has been commanded ON in either high gear or Overdrive.
What is the diagnostic code for transmission component slipping?
P0894 is a diagnostic trouble code (DTC) for “Transmission Component Slipping”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
When to use a p0894 transmission component slipping code?
This condition is usually accompanied by the distinctive odor of burnt friction material in the fluid. If the PCM detects a degree of transmission slippage that exceeds maximum allowable parameters, a code P0894 may be stored and a malfunction indicator lamp (MIL) illuminated.
What causes a slippage code on a PCM?
The PCM uses voltage input signals from the transmission input speed sensor and transmission output speed sensor to determine if the transmission is functioning efficiently and without slippage. As with many other automatic transmission malfunctions, a transmission slippage code may be caused by electrical or mechanical failure.
What causes a transmission slip on a 2006 Silverado?

Why does my transmission slip in and out of sync?
Slipping gears are usually due to normal wear and tear, which causes them to not engage properly and to slip in and out of sync. It is rare, but there might be a malfunctioning set of gears in the transmission, which is usually due to bad original manufacturing.
