TransGo 4L80E High Temperature Sealing Ring Kit

TransGo 4L80E High Temperature Sealing Ring Kit

The TransGo 4L80E High Temperature Sealing Ring Kit is designed for 1991-2013 GM vehicles with 4L80E and 4L85E transmissions. It addresses issues like no lock-up, no 4th gear, direct clutch slip, harsh shifts, and slip codes that occur when the transmission fluid is hot.

OE sealing rings lose effectiveness after heat cycles, causing leaks and slippage. This kit includes high-temperature sealing rings and expanders that resist hardening, preventing leaks and restoring reliable performance.
