Overheating is a common problem in Honda/Acura vehicles equipped with four-speed, 3 shaft and 5-speed transmissions. This condition can be caused by a worn or stuck TC check valve, which reduces working pressure in the torque converter and leads to excess heat buildup and TCC troubles. In some cases the TC check valve bore can be heavily worn, requiring an O-ring seal for proper repair. Restore correct converter pressure and prevent overheating and valve hang-up by installing Sonnax O-ringed TC check valve kit 98892-29K.

Some OE castings are machined with an edge remaining at the relief ports; this kit can be used to salvage those castings as well.

  • O-Ring helps seal heavily worn bores
  • Sleeve provides additional valve support to reduce excess wear and sticking
  • Sleeve manufactured from highly wear-resistant aluminum
  • Drop-in Zip Valve™ parts install quickly and easily
