When you’re shifting between ranges on your 6R and notice a puddle of transmission fluid under the range box, you’ve got a leaking gasket that needs attention. A worn transmission range box gasket lets precious fluid escape while letting dirt and moisture seep in—neither of which does your transmission any favors when you’ve got a long day of field work ahead.
What You’re Getting
- Precision-cut gasket that seals the range box housing completely
- OEM-quality materials that handle transmission fluid and temperature cycling
- Direct replacement design fits like the original factory part
- Durable construction that maintains its seal through thousands of shifts
Built for Real Farm Work
This gasket keeps your 6R series transmission sealed up tight, whether you’re running a 6140R on lighter tasks or pushing a 6215R through heavy field work. These tractors see everything from loader operations to heavy tillage, and that range box gets a workout shifting between field speeds and transport ranges all day long.
Made to Last
Farm transmissions deal with temperature swings from cold morning startups to running hot under load all afternoon. This gasket is built from materials that stay flexible in cold weather and won’t shrink or crack when things heat up, keeping that seal tight through countless heating and cooling cycles.
Installation Notes
Clean all the old gasket material off both surfaces before installing the new one—any leftover bits will cause leaks. A gasket scraper and some brake cleaner work well for this. Take your time torquing the bolts in sequence to avoid warping the housing, and let the sealant cure before adding fluid if you’re using any.
