Antonio Davila • 29 September 2025

Los Angeles Porsche owner discovers transmission oil leak during routine inspection. Euro-Tech Motors' dealer-trained technicians identified the original transmission pan as the culprit and performed complete PDK service to prevent further damage.


Quick Summary


  • Issue: PDK transmission oil leak
  • Vehicle: 2014 Porsche 911 Carrera 4S
  • Problem: Original transmission pan with built-in filter failing
  • Solution: Complete PDK transmission service with new pan
  • Location: Los Angeles service by Porsche specialists


PDK transmission oil leaks in 2014 Porsche 911 models typically stem from the original transmission pan deteriorating over time. Euro-Tech Motors' ASE-certified technicians discovered this exact issue during a comprehensive inspection, noting that the transmission had never been serviced since leaving the factory. The very dark transmission fluid confirmed our diagnosis - this PDK system was overdue for professional attention.


5 Signs Your Porsche PDK Transmission Needs Service


  1. Visible oil spots under the vehicle- Fresh oil stains appearing where you park
  2. Dark, contaminated transmission fluid- Original fluid should be bright red when new
  3. Rough shifting or hesitation- PDK systems require clean fluid for smooth operation
  4. High mileage without service- Many 991 generation cars have never had PDK service
  5. Oil spread across undercarriage- Highway speeds can distribute leaked fluid widely


What Our Porsche Specialists Found


During our detailed inspection of this 92,684-mile 911, our technicians discovered:


  1. Original transmission pan with integral filter- Never serviced since factory assembly
  2. Severely contaminated transmission fluid- Dark, degraded oil affecting system performance
  3. Active leak spreading during driving- High-speed operation distributed oil across vehicle underside
  4. Multiple maintenance needs- Perfect opportunity for comprehensive service


Our Specialized 4-Step PDK Service Process


  1. Complete system diagnosis- Pressure testing and fluid analysis using dealer-quality equipment
  2. OEM parts installation- New transmission pan with integrated filter and multi-point socket bolts
  3. Proper fluid replacement- 7 quarts of specified PDK coupling fluid for optimal performance
  4. Comprehensive area cleaning- Thorough degreasing to identify any future leak sources


3 Ways to Prevent PDK Transmission Problems


  1. Follow factory service intervals- Don't wait for leaks to develop before servicing
  2. Use only specified fluids- PDK systems require precise fluid specifications
  3. Address leaks immediately- Small seeps become major problems without prompt attention
