The procedure for replacing your 4l60e shift solenoids is as follows (if you havent started the process yet): When replacing your shift solenoids, now would be the perfect time to replace your transmission pan and filter, especially if you havent changed your fluid recently, or are wanting a transmission pan with a drain plug for future convivence. 35380A 700R4 4L60E Transmission output speed sensor 1987-95. rref-Solenoid charts.indd 77ef-Solenoid charts.indd 77 11/5/06 4:32:43 PM/5/06 4:32:43 PM << /ASCII85EncodePages false /AutoPositionEPSFiles true When the mode switch is closed, auto mode will be used, regardless of what you do with the shift buttons. The image below shows the locations of various solenoids. DTC will set if one of the following conditions occurs for 5 seconds: *Control module commands solenoid on and voltage remains high (battery voltage) *Control module commands solenoid off and voltage remains low (zero volts)" But I wouldn't be surprised if there are other issues that can throw this code. The difference is the addition of the "Lockup Feel" solenoids (aka. These are: The wiring inside the 4L60E transmission looks like this: The corresponding AMPseal connections for the control/sense functions are: The CAN termination resistors are already in place on the MS-II controller and GPIO board. 491g Package List: 1 x A Shift Solenoid 1 x B Shift Solenoid 1 x 3-2 Downshift Solenoid 1 x EPC (Pressure Control) Solenoid 1 x TCC/PWM Solenoid When your 4l60es TCC solenoid begins to fail, there are a number of obvious signs. Find the best prices on all 4l60e shift solenoids. With this information in mind, it becomes apparent how a torque converter that was built perfectly to specification can fail due to being installed in an improperly modified transmission. However, when they go bad, you will notice very quickly. There are 2 shift solenoids in a 4l60e (1-2 and 2-3), and both control up and downshifts with fluid passing through them when commanded to do so by the computer. Figure 2 shows PWM progression during typical TCC application. Works at 16 ohms ONLY Come to my house and try it.
