Condition
Some customers may comment that intermittently the vehicle may not go above 30 mph, may
be stuck in 2nd gear, will not upshift, MIL is on, and/or DTC P2821 set.
Cause
If you encounter a vehicle with the above concern, perform the diagnostic procedure for the
DTCs set in SI.
Correction:
If the diagnostics procedures have found no conditions that set the codes, inspect the Control Valve Body spacer plate Orifice #33 for
blockage.
Note : This spacer plate is between the trans assembly case and the valve body assembly, item #456, using SI #4368440.
If the orifice is blocked, replace the spacer plate with a new one.
NOTE: Since the hole is only 0.5 mm in diameter the best way to inspect is to shine a light from behind the spacer plate and look for
the light through the hole.
Engineering continues to investigate this concern and this P/I will be updated or advanced to a TSB, if needed.
