Description
When you’re deep in harvest or working against the weather, the last thing you need is your tractor slipping out of gear or losing power under load. Deep inside your powershift transmission, this piston seal maintains the hydraulic pressure that engages each clutch pack. When it starts to fail, you’ll notice gear slippage, slow shifting, or complete loss of certain ranges – problems that can bring your work to a standstill.
What You’re Getting
- Critical hydraulic seal that maintains clutch pack engagement pressure
- Heat-resistant materials designed specifically for transmission service
- Precision dimensions ensure proper sealing under extreme hydraulic pressures
- Advanced compound resists hardening from heat and transmission fluid exposure
- Direct replacement for worn seals in powershift clutch pistons
Built for Real Farm Work
This seal fits New Holland T6, T7, and TM series tractors with powershift transmissions – machines commonly used for row-crop farming, hay operations, and heavy field work where reliable shifting under load is essential. These tractors depend on precise hydraulic control to engage different clutch packs for seamless power delivery, whether you’re pulling a planter uphill or pushing through heavy ground with a disk.
Made to Last
Powershift transmissions create intense hydraulic pressures and high temperatures during clutch engagement. This seal uses materials specifically formulated to handle those conditions without becoming brittle or losing its sealing ability. The compound maintains flexibility even after thousands of engagement cycles, ensuring long-term reliability in demanding farm conditions.
Good to Know
This is a major transmission repair requiring complete disassembly – not something you tackle in the field. Take lots of pictures during teardown to document clutch pack stacking sequences, as incorrect assembly causes immediate failure. Keep everything absolutely clean during the rebuild, and plan to replace transmission fluid and filters while you’re in there. If one seal failed, others are likely close behind.
