Transmission Slipping Symptoms

Slipping means the transmission isn't transferring engine power to the wheels properly. Here are the symptoms and common causes.

Symptoms

• RPM flare when shifting — Engine revs up between gears; car feels sluggish
• Delayed engagement — Delay when shifting into Drive or Reverse
• Slips under acceleration — Engine revs but car doesn't accelerate
• Harsh or jerky shifts — Abrupt gear changes

Common Causes

• Low fluid — Check level first. Add correct fluid if low.
• Burnt fluid — Brown color, burnt smell. Overdue service. Drain and fill may help if caught early.
• Worn clutch packs (automatic) — Mechanical wear. Requires rebuild or replacement.
• Torque converter issues — Shudder, slip, or delayed engagement.

CVT-Specific

CVTs can shudder, whine, or slip if fluid is wrong or worn. Use only CVT-specific fluid. Wrong type can destroy the unit.
