TV-Boostvalve TH125

TV-Boostvalve TH125 Common problems in a THM 125-C transmission are burned clutches or bands, poor line rise response or delayed reverse engagement. These problems are frequently caused by a worn TV and reverse boost valve sleeve. The steel TV and reverse plungers continuously oscillate in the aluminum sleeve, which can cause wear resulting in oil cross leaking or exhausting. This oil loss can prevent the pressure regulator valve from reaching higher line pressure (maximum pump output) positions. The Sonnax replacement TV and reverse boost valve assembly 75918-01K eliminates these problems
