Embodiment Construction

[0041] Such as Figure 3A and 3B As shown, what is shown in the figure is the TCC regulating valve assembly 10 consistent with the present invention. The TCC regulator valve assembly 10 includes a replacement modulating action valve 20 , a new modulating action valve sleeve 15 , and a replacement isolation valve 25 . The OEM isolation valve compression spring 106 and OEM retaining clip 117 can be reused in this invention. OEM end plug 115 (see Figure 1A ) are effectively integrated into the regulating action valve sleeve 15 of the present invention, therefore, the OEM end plug 115 can be discarded.

[0042] see Figure 4 , shown is an alternative modulating action valve 20 of the present invention, which includes a pair of control lands A42, B45, connected to each other by a connecting portion 43, possibly with a surrounding groove (not shown in shown in the figure) for easy identification. The spring positioning diameter 40 is coaxial with the control land 42 and is use...

Abstract

The invention discloses a torque converter clutch regulating valve assembly and a method for increasing hydraulic pressure by using the same. It consists of mainly two cooperating valves, a replacement modulating apply valve and a replacement isolation valve, in hydraulic communication with the main line pressure circuit and the torque converter clutch apply circuit. In one embodiment, the modulating action valve utilizes a modulating action valve sleeve which provides support for the modulating action valve to avoid edge loading. The improved control land on the modulating action valve has a reduced cross-sectional area to increase the effect of the pulse width modulated solenoid, which provides an output pressure in response to the solenoid coil in the pulse width modulated converter system. Applied duty cycle. In another embodiment, isolation valve sleeves are used when the isolation valve bore is so worn that it cannot be repaired by simply installing a replacement isolation valve.

Description

technical field [0001] This invention is related to the hydraulic circuit in the automatic transmission system, more specifically, it relates to a torque converter clutch (hereinafter referred to as "TCC") replacement regulator valve that can reduce the torque converter action and hydraulic loss in the release circuit, And here the torque converter apply and release circuit is used to drive the torque converter clutch. Background technique [0002] General Motors 4L60-E (hereinafter "GM") transmissions and other similar GM transmissions have mechanisms that "lock up" their torque converters to varying degrees depending on certain operating conditions. The purpose of the lock-up torque converter is to provide direct drive when the vehicle is running steadily at high speeds. Since there is always some slippage in the hydraulic coupling of the torque converter, some power will be lost and fuel economy will also be reduced. The lock-up torque converter improves fuel economy by...
