This concern may be caused by a worn reverse boost valve and sleeve. Replacing the reverse boost valve and sleeve may be needed to repair this concern. PH Page 1 of 1
Transmission: Subject: Application: Issue Date: Technical Bulletin #1633 5L40/5L50 Shift Concerns & Quality After Repair or Software Update, Downshift Clunks Cadillac CTS, SRX, XLR, STS August 5L40/5L50 Shift Concerns & Quality After Repair or Software Update General Motors recommends clearing shift adapts and using the following relearn procedure in these situations: 1. Transmission replace or major overhaul 2. TCM replacement or reflash 3. Valve body replacement After any of the above repairs, the adaptive values have to be erased. These cells then need to be refilled to get an optimal shift quality. However, only coast downshifts will require special care as described below: Coast Downshift Adapt Procedure: Drive Range (D5) at normal transmission operating temperature. 1. 45 mph, light brake to a stop, about 13 seconds 2. 45 mph, moderate brake to a stop, about 6 seconds 3. 25 mph, coast to about 5 mph Repeat the above steps 3 times each.

#1634 Honda 5 Speed Kills the Engine in Drive, No Reverse Reverse Hydraulics Normal Operation During normal reverse operation shift valve A and the reverse control valve are in the shifted position. The reverse control valve opens line oil to the servo valve. This strokes the servo valve into the reverse position. Shift valve A allows line oil from the servo valve to apply the 5th clutch. BB Page 3 of 6
Honda 5 Speed Kills the Engine in Drive, No Reverse #1634 Reverse Hydraulics With Normally Open Solenoids (Wrong Parts Installed) When N.O. solenoids are installed oil is blocked from getting to the servo valve and the 5th clutch. In reverse the computer commands shift solenoid A ON and shift solenoid D ON. This will close the solenoids and the servo control valve and shift valve A will stay in the unshifted position.

#1634 Honda 5 Speed Kills the Engine in Drive, No Reverse Lockup Hydraulics Normal Operation During normal operation the lockup valves are in the unshifted postion. When lockup is commanded by the controller the solenoid opens and flows fluid to the lockup shift valve. BB Page 5 of 6
Honda 5 Speed Kills the Engine in Drive, No Reverse #1634 Lockup Hydraulics with a Normally Open Solenoid (Wrong Parts Installed) The normally open solenoid flows pressure to the lockup shift valve. This blocks converter charge oil from releasing the converter clutch. The applied converter clutch kills the engine when put into gear. BB Page 6 of 6

Normally low solenoids provide hydraulic pressure proportional to supplied current. A normally low solenoid will output very low pressure with low (50 ma) or no current, while it will supply high pressure with high current (850 ma). Normally high solenoids provide pressure inversely-proportional to supplied current. Normally high solenoids provide full output of pressure with low or no current (50 ma) and very low pressure with high current (850 ma). Refer to the illustration below for solenoid identification.

There are (2) types of solenoids, normally high and normally low solenoids. The solenoids can be replaced separately, but only with the same type of solenoid. The replacement solenoid band number must match the band number of the solenoid being replaced. The band number is printed on the side of the solenoid and will be a 2, 3, 4 or 5. JW Page 4 of 4
