T90 Transmission Parts

The T90 manual transmission is a classic three speed gearbox commonly found in early Jeep vehicles. Known for its simple design and dependable operation, the T90 remains a popular choice among restorers and off road enthusiasts who value durability, ease of service, and long term reliability. As these transmissions age, internal components can wear due to mileage, lack of lubrication, or demanding use. Advance Adapters offers a focused selection of replacement parts designed to support accurate rebuilding and dependable operation of the T90 transmission.

This category includes essential internal components needed for proper service and restoration, including:

• Cluster gears for the main gear train
  
  
• Input shafts with correct spline count and dimensions
  
  
• Small parts kits for complete rebuilds
  
  

The cluster gear is one of the most critical components inside the T90 transmission and is often one of the first to show wear. A worn cluster gear can lead to increased noise, rough shifting, and accelerated wear on mating gears. Replacing this component helps restore smooth operation and reduce drivetrain noise.

Input shafts transfer engine power into the transmission and must maintain proper spline engagement and alignment with the clutch system. Advance Adapters input shafts are manufactured to precise specifications to ensure correct fitment and reliable performance.

Small parts kits provide the hardware required for a complete rebuild, including bearings, thrust washers, snap rings, and other wear items. Using a matched kit helps ensure compatibility and reduces the risk of premature failure caused by mixing old and new components.

Whether you are restoring a vintage Jeep or maintaining a working vehicle, Advance Adapters provides the parts needed to rebuild the T90 transmission with confidence.
