Transmission Friction Element D Temperature Too High

Check these first

• Low or contaminated transmission fluid raising friction element D temperature
• Slipping clutch packs for friction element D building heat
• A restricted transmission fluid cooler or line
• A failed transmission fluid temperature sensor skewing the reading

What to do next

1. Read transmission fluid temperature and friction element D data on a scan tool
2. Check transmission fluid level and condition
3. Inspect the transmission fluid cooler and lines for restriction
4. Check for slipping on friction element D
5. Repair or replace friction element D if it is slipping
6. Clear the code and retest
