A transmission filter includes a baffle with a valve. The baffle defines front and rear openings. When a vehicle climbs or descends a hill, the valve moves in response to the weight of fluid on a higher side of the baffle. The valve prevents flow from the higher of the front and rear openings preventing air ingestion into the filter.

Transmission filter

A park-by-wire system uses a single spring to bias the system towards park and to permit a ratcheting feature which delays the engagement of park until vehicle speed drops below a threshold. A cam slides with respect to a rod. A stop on the rod limits travel in one direction. The spring biases the cam toward the stop but compresses as necessary to allow the cam to move during ratcheting operation. The spring reacts against the housing. Acting through the cam and the stop, the spring biases the rod toward the park position. The design limits the number of components that move during ratcheting operation. Specifically, the rod and actuator do not oscillate during ratcheting operation.

Transmission park mechanism

A transaxle for a vehicle has a case adapted to retain a transaxle oil. A chain transfers torque between transaxle gears, and a snubber is disposed along the tension side of the chain. The snubber comprises a molded base plate with a pair of mounting inserts extending transverse to the base plate to mount the snubber to a case of the transaxle. A snubber plate is integrally molded with the base plate and extends substantially transversely from a longitudinal side of the base plate to frame an edge of the chain. A ramp plate is integrally molded with the base plate and extends substantially transversely from the base plate and obliquely with respect to the snubber plate. A scoop is integrally molded with the base plate and extends from the ramp plate configured to transversely deflect a flow of transaxle oil directed to the scoop by the ramp plate.

A pump suction line assembly includes a sump including a wall formed with a bore and a seat, a tube including an inlet, an outlet, a length connecting the outlet and inlet, and a flange contacting the seat, a housing, a seal fitted in the bore and contacting the flange and the housing, and fasteners that compress the seal, secure the tube to the wall, and secure the sump to the housing.

Hydraulic suction line

The automatic transmission for motor vehicles includes a positive displacement pump, a sump hydraulically connected by a passage to the pump inlet, a line pressure control valve having a high pressure outlet, a passage carrying fluid from the control valve through a nozzle and an nozzle exit opening to the passage that connects the sump to the pump inlet. The high pressure passage has a cross section whose area decreases in the direction toward the pump inlet and terminates in a nozzle through which a high speed jet enters the low pressure passage through the nozzle exit opening.

In a hydraulic system for controlling the rate at which fluid flows to an oncoming clutch and for quickly disengaging the clutch, a source of pressurized fluid, a valve hydraulically connected to the fluid source including a spool for alternately opening and closing communication through the valve between the fluid source and the clutch, a seat located between the valve and the clutch, and a plate moveable by fluid flow in a first direction into contact with the seat and moveable by fluid flow in a second direction away from the seat, the plate having an orifice through which fluid enters the clutch when the plate contacts the seat, and openings through which fluid from the clutch passes when the plate is away from the seat. A tube, located between the plate and the clutch, includes a head adjacent the plate and is formed with the seat, and a shank having a passage hydraulically communicating with the clutch, the orifice being aligned with the passage when the plate contacts the seat.
