Question 1

Which of the following components needs to be removed from the 6T40 transmission before the fluid baffle?

Accepted Answer

All of these components need to be removed to access the fluid baffle.

Question 2

When disassembling the 6T40 transmission, removal of which component will also require removal of the center support from the transmission?

Accepted Answer

Removal of the front planet carrier and two thrust bearings will also require removal of the center support from the transmission.

Question 3

What measurement should be performed to check whether the overdrive/direct clutch assembly is installed properly on a GM 6T40 transmission?

Accepted Answer

The distance from the top of the intermediate steel plate to the lip of the transmission case in three different places should be measured to check whether the overdrive/direct clutch assembly is installed properly on a GM 6T40 transmission.

Question 4

If a precision bar and depth gauge are being used to measure the distance between the long legs of the center support and the low/reverse piston of a GM 6T40 transmission, what must be done to get a correct calculation?

Accepted Answer

The thickness of the precision gauge must be subtracted from the measurement to account for the gauge's presence in the measurement path, ensuring an accurate calculation of the actual distance.

Question 5

The assembly of the forward clutch pack is being discussed. Technician A says that if the clutch pack clearance measures between 0.051" and 1.83", the clutch pack is installed correctly. Technician B says that if the clutch pack clearance is between 0.002 mm and 0.072 mm, the clutch pack is installed correctly. Who is correct?

Accepted Answer

Both Technician A and Technician B provide incorrect clearance measurements for the forward clutch pack. The correct clearance is typically much smaller than the values they mentioned.

Question 6

Final reassembly of the 6T40 transmission is being discussed. Technician A says that it is acceptable to reuse the transmission case gasket if it is not damaged. Technician B says that the transmission case gasket should always be replaced. Who is correct?

Accepted Answer

The answer of Final reassembly of the 6T40 transmission is...

Question 7

The GM 6T40 transmission was developed jointly between GM and Ford.

Accepted Answer

The answer of The GM 6T40 transmission was developed jointly...

Question 8

Technician A says that the 6T40 GM transmission uses DEXRON VI transmission fluid . Technician B says that the 6T40 GM transmission uses DEXRON IIE transmission fluid . Who is correct?

Accepted Answer

The 6T40 GM transmission uses DEXRON VI transmission fluid, making Technician A correct. DEXRON IIE is an older specification not used in this transmission.

Question 9

Technician A says that the Ford transmission fluid level can be inspected with a dipstick. Technician B says that the GM transmission can also be inspected with a dipstick. Who is correct?

Accepted Answer

The answer of Technician A says that the Ford transmission...

Question 10

The 6T40 transmission uses a temperature sensitive fluid control valve that allows fluid to return to the sump area until it reaches 60°F.

Accepted Answer

The 6T40 transmission does not specifically use a temperature-sensitive fluid control valve that operates at 60°F. This description does not accurately reflect the design or operation of the 6T40 transmission.

Question 11

Which of the following statements is NOT true regarding the 6T40 transmission?

Accepted Answer

The 6T40 transmission does not have six planetary gears; it typically has fewer.

Question 12

Technician A says that when a solenoid is faulty, the entire solenoid pack must be replaced. Technician B says when replacing the solenoid pack, a unique identification code must be programmed into the vehicle's PCM. Who is correct?

Accepted Answer

Both technicians are correct. A faulty solenoid often requires replacing the entire solenoid pack, and when replacing it, a unique identification code typically needs to be programmed into the vehicle's PCM to ensure proper operation.

Question 13

On a GM vehicle with a 6T40 transmission, the temperature of the transmission fluid can be displayed:

Accepted Answer

The transmission fluid temperature can be displayed with a scan tool or on the driver's information center.

Question 14

Technician A says that when testing the solenoids, they should be tested directly. Technician B says that the resistance of the solenoids varies with their temperature. Who is correct?

Accepted Answer

The resistance of the solenoids varies with their temperature.

Question 15

The 6T40 transmission disengages the forward clutch when the brake is applied.

Accepted Answer

The 6T40 transmission is designed to disengage the forward clutch when the brake is applied to prevent the vehicle from moving forward, ensuring safety and control.

Question 16

Technician A says that the shift solenoids A, B, C, and D are on and off solenoids. Technician B says that shift solenoid E is the only variable-force solenoid. Who is correct?

Accepted Answer

The answer of Technician A says that the shift solenoids...

Question 17

Identify the component of 6T40 transmission shown in the given figure

Accepted Answer

The answer of Identify the component of 6T40 transmission shown...

Question 18

Tech A states that the 6T40 is basically the same design as 6T45. Tech B states that the 6T40 is basically the same design as 6T50. Who is correct?

Accepted Answer

The answer of Tech A states that the 6T40 is...

Question 19

Identify the smaller version of 6T40 transmission.

Accepted Answer

The 6T35 is a smaller version of the 6T40 transmission, designed for smaller vehicles or those requiring less torque capacity.

Question 20

Tech A sates that 6T30 is the smaller version of 6T40. Tech B states that 6T50 is the smaller version of 6T40. Who is correct?

Accepted Answer

The 6T30 is indeed a smaller version of the 6T40 transmission, while the 6T50 is a larger version.
