Signs Your Vehicle’s Transmission Needs Attention

  • Momentary delay in movement after placing the vehicle in gear

  • Long gear shifts, or gear slippage when attempting to accelerate
  • Vehicle surges while you are maintaining a constant speed

Know Your Vehicle’s Transmission Fluid Specification

Consult your owner’s manual for your vehicle’s specified automatic transmission fluid if the fluid level is low. PEAK Full Synthetic Multi-Vehicle ATF meets most popular vehicle ATF specifications. If the fluid level is acceptable, your vehicle may only need a transmission fluid flush but there may be more going on. PEAK recommends you see a transmission service professional ASAP.

PEAK’s general recommendation is to flush your transmission every 2 years or 30,000 miles.
