A worn lockup relay valve sleeve due to continuous oscillation of the lockup relay valves can cause these complaints. Wear in the 1st land (see illustration) may cause a loss of Solenoid 3 signal pressure, which may prevent the valve from stroking fully into the TCC apply position. When the TCC is signaled ON, wear at the 2nd and/or 3rd lands may allow converter apply pressure to leak to exhaust, creating reduced apply pressure and cooler flow.
