Hard Shifting Fixed ( Verified Buyer )
5 out of 5 stars.
Tal (Georgia) | April 20th, 2026
My 07 Carrera S has been hard to shift in 1/2 gears since new. Adjusted shift lever, but the same. With this oil is totally fixed the problem. Now it’s very smooth and shifts into 1st and 2ned as it should.
Less Crunch
4 out of 5 stars.

1995 993 C2 37K miles manual. Noticed much improvement when starting out from a cold Minnesota winter. Eases into third gear much easier with much less crunch. As good as this oil is it's still oil and way overpriced,.
Nice improvement in shifting feel
5 out of 5 stars.
JPA (South Carolina) | July 4th, 2020
For my 2003 996 with 75k miles I updated to the 997 shifter console which gave a slightly shorter more precise throw and then after a few weeks changed to Mobil PTV 75W-90. The change in lube made as big an improvement in feel as the console change except the change was to the smoothness of the shifter movement. Now the car really shifts the way I want. Amazing was less than 3 liters of a different lube can make. Strongly recommended.
Smoother shifts, at least when warm
4 out of 5 stars.

This made the shifting better in by 997.1 C4S when the tranny is warm. Not as big an impact when cold as others have reported.

I have a 07 carrera that was hard to shift when cold. I tried several other sythetic 75w90 oils and all were the same. my tech told me to try the factory PTX and it was amazing. Cold crunch when shifting is gone, smother all around. with I had done it years ago. well worth the extra cost to get it right.
Amazing performance, overpriced .
4 out of 5 stars.
Nis (Socal) | April 20th, 2016
The ptx is an amazing product. Best tranny oil for porsche but way too expensive. Initially I thought it was a gallon based on the pic, boy was I wrong!!...had to reorder 2 more. The shifting is much smoother now because of the ptx but it's price is outrageous $40/quart.
Works
5 out of 5 stars.

I bought 3 liters for my 2008 C4 manual to do general maintenance at 40k miles. Easy DIY task.
Fixes notchy shifting

2009 C2S 86K miles manual. I had the classic jamming going into 1st. This fixed it. My manual denotes changing this at 120K miles.... BS.... it should be changed earlier. I don't know why or what was wrong, but changing this out for what is recommended in my manual cures this ill.

Porsche Parts Warranty Information — Suncoast Porsche

Understanding your warranty coverage is important. Below is a complete overview of warranty terms for Genuine Porsche OEM parts, aftermarket parts, and closeout items purchased from Suncoast Porsche and SuncoastParts.com.

Warranty Coverage by Product Type

Genuine Porsche OEM Parts — 2-Year Warranty

All Genuine Porsche OEM parts purchased from Suncoast Porsche or SuncoastParts.com come with a 2-year, unlimited mileage, parts-only warranty beginning on the date of purchase.

If your parts are installed at an authorized Porsche Service Center, both parts and labor warranty coverage may apply if the part is deemed defective within the 2-year warranty period. Coverage varies by location — please check with your local Porsche dealer prior to installation to confirm their specific warranty participation, as each Porsche Center is independently owned and operated.

Important warranty notes for online purchases:

  • Labor, diagnostic, and installation fees are not covered when parts are purchased online from SuncoastParts.com or Suncoast Porsche, unless the parts are installed by an authorized Porsche Service Center
  • Warranty claims must be processed in person at an authorized Porsche Service Center
  • Warranty service is honored at any authorized Porsche dealer in the United States, however some dealers may decline warranty claims for parts purchased online or from another dealership — always verify with your local dealer before installation
  • If a warranty claim is approved and the part was not installed by a Porsche Service Center, installation of the replacement part remains the customer's responsibility
  • Suncoast Porsche and SuncoastParts.com are not liable for any diagnostic, labor, or installation fees charged by another Porsche Service Center

Aftermarket & Performance Parts

Warranty coverage for aftermarket and performance parts varies by manufacturer. Most carry a 1-year limited warranty. Contact us for specific warranty details on any aftermarket product. Please note that diagnostic time and labor costs for warranty replacements are not covered.

Take-Off & Closeout Parts

All take-off and closeout parts are sold as-is with no warranty and are not eligible for return. Pricing on these items reflects their as-is condition.

What This Warranty Does Not Cover

The following situations and conditions are explicitly excluded from warranty coverage:

  • Improper Installation or Misuse — Damage resulting from incorrect installation, negligence, unauthorized alteration, or accident. This includes any use in racing, competition, or motorsport applications
  • Lack of Proper Maintenance — Damage caused by failure to follow the vehicle's recommended Maintenance Schedule, or failure to use the correct fluids, fuel, oil, or lubricants as specified in the Owner's Manual. Proof of proper maintenance is the owner's responsibility — retain all service receipts in case questions arise
  • Consequential or Economic Losses — Towing fees, rental vehicles, loss of use, loss of time, inconvenience, or any other indirect economic losses
  • Vehicles Outside the USA & Canada — Parts installed on vehicles registered or primarily operated outside of the United States or Canada are not covered under this warranty

How to Obtain Warranty Service

Installed by an Authorized Porsche Dealer

If your parts were originally installed by an authorized Porsche dealer, warranty repairs may be performed by that same dealer or any other authorized Porsche Service Center in the United States. Please allow a reasonable timeframe for repairs after delivering your vehicle to the dealership.

Installed by an Independent Repair Shop

Please be aware: All warranty claims must be inspected, performed, and documented by factory-trained Porsche technicians at an authorized Porsche dealership. Work performed at an independent repair shop does not qualify for warranty consideration. If warranty coverage is a priority, we strongly recommend having your parts installed at an authorized Porsche Service Center.

Documentation Requirements for Warranty Claims

To process a warranty claim, the servicing Porsche dealer will require:

  • Your original sales receipt or order confirmation from SuncoastParts.com or Suncoast Porsche
  • A completed warranty certificate
  • Proof of proper vehicle maintenance history (if applicable)

Suncoast Porsche retains sales records on file for two years. If you need a copy of your receipt, contact us and we will provide it promptly.

Additional Warranty Terms & Legal Disclaimers

This warranty provides you with specific legal rights. You may also have additional rights that vary by state.

Porsche does not authorize any individual or organization to create additional obligations or liabilities beyond those stated in this warranty. Any implied warranty of merchantability or fitness for a particular purpose is limited in duration to the term of this written warranty. The exclusive remedy under this warranty is the repair or replacement of the defective part.

Suncoast Porsche and SuncoastParts.com shall not be liable for any incidental or consequential damages arising from a breach of this written warranty or any implied warranty.

Some states do not permit limitations on implied warranty duration or the exclusion of incidental or consequential damages — the above limitations may not apply in your state. Additionally, installation of certain parts or accessories may affect your Porsche New Vehicle Warranty. Please consult your authorized Porsche dealer for full terms, or contact us with any questions.

IMPORTANT NOTE: Please consult a technician, owners manual, or workshop manual before selecting and using any of the oils or fluids shown. Shipping on these items is restricted to the lower 48 states.
