How do you replace a low reverse servo cover?
How do you replace a low reverse servo cover?
First remove the low-reverse servo cover and piston (C4 and C5 only). Inspect the piston for damage and a worn seal. Replace the low-reverse piston in any case. Remove the throttle valve (vacuum modulator), including the valve body control rod (pin) inside the case.
Can a pre 96 reverse servo be installed?
Installing the early Pre 96 type reverse servo assembly can reduce servo problems when max reverse pressure is within spec. • Some extreme usage vehicles, snow plows etc., may need a higher max pressure in reverse to keep the band from failing. If you have one these special situations give one of our techs a call.
When to test reverse low servo cavity in TransGo?
If there’s no hold back during the coast braking this indicates the complaint is associated to the reverse/low band & components. Pressure testing: We strongly recommend taking Line Pressure readings when diagnosing transmission problems, especially a slipping or no reverse concern.
What causes a reverse servo not to work?
If it exceeds 325psi this can lead to failed reverse components. Suspect a worn EPC boost bushing when max reverse pressure is too high. Installing the early Pre 96 type reverse servo assembly can reduce servo problems when max reverse pressure is within spec.
