Turns in the same direction as the input shaft B. Turns at the same speed as the input shaft (correct answer) C. Does not run D. Turns in the opposite direction as the input shaft. (not the answer) If direct and forward clutch packs in a common 3 speed automatic transmission are applied at the same time. What will the resulting condition be? - - A. Direct drive B. Low gear C. Reverse gear D. A jammed or locked up transmission, with no drive, forward or reverse. (not the awnser) In the picture below the mechanic is checking: - - A. Pump driven gear tip clearence B. Pump body to case seal C. Gear contact pattern D. Pump body to gear face clearance. (correct answer) Multiple-disc clutch packs in automatic transmissions are usually applied by: - - A. Hydraulic pressure on a piston. (correct answer) B. Spring pressure C. Govenor pressure D. Spring pressure and a roller clutch. (not the answer) MECHANIC MECHANIC Which of the following is likely to cause burned clutch plate bands? - - A. Internal leaks due to damaged seals. (correct answer) B. A defective governor. C. A leaking modulator. D. None of the above. Automatic transmission fluid that looks like a chocolate milkshake may indicate: - - A. A leaking radiator cooler. (correct answer) B. Too much automatic transmission fluid(overfilled). C. A sticking pressure relief valve. D. The fluid is aerated. (not the answer) A transaxel assembly: - -a. Always bolts directly to the differential. B. Is a transmission and differential assembly in one common case. (correct answer) C. Is exlusively front wheel drive. D. Has no vent. What would be the result if the sun gear was the input member, the carrier was held, and the ring gear was the output member? - - A. Direct drive B. Overdrive (not the answer) C. Torque reduction D. Reverse When checking a spool valve from the valve body, you notice it has very square ans sharp edges on its lands. What should you do? - - A. Gently chamfer the land edges with a fine sharpening stone. (not the answer) B. Nothing. This is a desirable condition. C. Replace the spool valve with a new one of the exact same part number. D. Smooth the edges with crocus cloth to restore a slight chamfer. High engine idle speed will likely cause: - - A. Harsh engagement from neutral to drive. B. Low line pressure and early upshifts. (possible correct answer) C. Direct upshift from first to third. D. All of the above. (not the answer) You have removed the transmission from a car and the torque converter. What should you do next? - - A. Measure and record input shaft endplay. (correct answer) B. Remove the pump. C. Measure clutch pack clearances. D. Inspect for planetary gear set wear. You are checking the fluid level in a transmission. Which of the following is correct? - - MECHANIC MECHANIC A. The level will be low when cold and rise when hot. (correct answer) B. The level will be high when cold and drop when hot. C. The level will not be affected by its temperature as long as the vehicle is parked on a level surface. (not the answer) D. The level may be low when cold on some vehicles and high on others. Incorrect adjustment of the linkage between the shift lever and the manual valve could cause: - - A. Slippage of clutches and bands B. Delayed clutch application. C. Early transmission failure. D. All of the above. (correct answer) A vehicle wont downshift into passing gear. The likely cause could be: - - A. The govenor valve is malfunctioning. B. A worn 2-3 shift rail. C. The throttle cable or linkage is out of adjustment. (correct answer) D. None of the above. Which of the following should be the average line pressure in drive at idle? - - A. 10-15 psi B. 50-70 psi (not the answer) C. 80-95 psi (possible correct answer) D. 125-140 psi As engine vacuum drops, the modulator pressure: - - A.
