Many people including Nissan techs do not understand this.... The 7AT transmission pump supplies trans fluid under pressure, to the torque converter piston/clutch to force it into the "off" position.

The 7AT transmission pump supplies trans fluid under pressure, to the torque converter piston/clutch to force it into the "off" position. So, to apply the converter clutch, the convert clutch solenoid just turns off the pressure to the piston, and the clutch comes on. If there is a malfunction of the converter clutch piston, piston seals or converter clutch control solenoid, the clutch may be "on" even at idle, causing the engine to stall when put into gear. It would drive like a newbe trying to drive a stick.... Doesn't happen often, but does happen as I have seen this condition before. |
