Abstract
PURPOSE: To prevent the upshift to the 4th speed in an automatic transmission by allowing the oil connected to the oil chamber to fix the 3rd-4th shift valve to the 3rd speed and the oil line supplied with oil pressure when the manufal valve is shifted to the 3rd range to communicate with each other through the 2nd-3rd shift valve.
CONSTITUTION: In an oil pressure controller for a four-speed automatic transmission, an oil line 114 connected to an oil chamber 243 to fix a 3rd-4th shift valve 240 to the 3rd speed and an oil line 107 supplied with oil pressure when a manual valve 210 is shifted to the 3rd range are allowed to communicated with each other through a 2nd-3rd shift valve 230. With the manufal valve 210 shifted to the 3rd range, when a spool 232 of the valve 230 is on the 2nd speed side, oil lines 104 and 114 are allowed to communicated with each other and when the spool 232 is on the 3rd speed side, the oil lines 107 and 114 are allowed to communicated with each other. Accordingly, even when the spool 232 is not smoothly moved owing to malfunction of solenoid valves 320 and 330 or the like, the upshift to the 4th speed can be reliably prevented.
