Our kit contains all the fluids, filters, gaskets & seals you need to refresh your S550 Ford Mustang's drivetrain.

Top Tec ATF 1850:

Liqui Moly's latest generation of low-viscosity high performance automatic transmission fluid based on synthetic technology. With modern, powerful additive components. Guarantees outstanding aging and oxidation stability as well as ideal shifting under all operating conditions thanks to its extremely high viscosity index. Makes long oil change intervals possible.

Developed for 6, 8 and 10-speed automatic transmissions as well as differential electric drives which are installed in various vehicles from Cadillac, Chevrolet, Ford, GMC and Lincoln.

Ultra-Guard® LS:

BG Products Ultra-Guard LS is a revolutionary multi-purpose synthetic gear oil compatible with all car and truck applications calling for GL-5 gear oil, especially those requiring limited slip function. It has shown proven performance in Traction-Lok and Torsen differentials found in the S550 Mustang.

It is a fully synthetic API GL-5 rated gear lubricant blended to SAE 75W-90 viscosity to provide the the ultimate protection for driveline components. It is formulated for maintaining system cleanliness, increased thermal stability, improved seal performance, quieter operation, and unsurpassed protection against wear, pitting, and corrosion.

Universal MGC:

BG Products MGC (Multi Gear Concentrate) prevents chatter in plate and clutch limited slip differentials. It contains specialised ingredients that ensure smooth and quiet differential gear operation and fortify gear lubricant additives.

Limited slip differentials can experience a loud chatter while turning caused by too much friction between plates in the system. BG Products MGC enhances lubricant film strength, improves thermal stability, and improves extreme pressure characteristics of any gear oil.
