XMSN Solenoid #1 Current (A) XMSN Charge Pressure (kPa) XMSN Valve #1 Pressure (kPa) XMSN Valve #2 Pressure (kPa)
Both clutch valves commanded OFF. ~ 0 A 2620 200 kPa (380 29 psi) ~ 0 kPa (~ 0 psi) ~ 0 kPa (~ 0 psi)
XMSN Clutch #1 commanded at 1100 kPa (160). ~ 1.0 A 2620 200 kPa (380 29 psi) 1100 200 kPa (160 29 psi) ~ 0 kPa (~ 0 psi)
XMSN Clutch #1 commanded at 2550 kPa (370). ~ 1.9 A 2620 200 kPa (380 29 psi) 2550 200 kPa (370 29 psi) ~ 0 kPa (~ 0 psi)
XMSN Clutch #2 commanded at 1100 kPa (160). ~ 1.0 A 2620 200 kPa (380 29 psi) ~ 0 kPa (~ 0 psi) 1100 200 kPa (160 29 psi)
XMSN Clutch #2 commanded at 2550 kPa (370). ~ 1.9 A 2620 200 kPa (380 29 psi) ~ 0 kPa (~ 0 psi) 2550 200 kPa (370 29 psi) Result 1: The XMSN clutch Solenoid #2 current is incorrect. Troubleshoot the XMSN harness and ECM.Result 2: The XMSN charge pressure is low during all portions of the clutch test procedure. Troubleshoot the XMSN charge pump and hydraulic circuit.Result 3:The XMSN clutch #2 pressure is incorrect. If unable to build clutch pressure, swap the clutch valves to see if the low pressure problem follows the valve. If it does, replace the valve corresponding to the low clutch pressure. If the issue does not follow the valve when swapped, remove the manifold and inspect the manifold seals. If the seals are good, contact product support for further troubleshooting information.Result 4: The XMSN clutch #2 valve pressure is correct. Pull the transmission suction screen. If considerable material is found, contact product support. Some metal shavings are expected with normal transmission operation.Note: If the clutch pressure test & visual inspection yield results within specification, contact product support for further information.E2302 Transmission Slip Detected in Second Reverse Range
Machine Response:Transmission unable to engage in high reverse Range from low reverse or unable to transmit the appropriate level of torque in high reverse Range.Note: Troubleshoot all related electrical diagnostics prior to starting this troubleshooting procedure. Related diagnostics include: (CID 1401) XMSN Solenoid #1. (CID 669) XMSN Input Speed Sensor (CID 2820) XMSN Planetary Speed Sensor (CID 585) XMSN Output Speed Sensor #1 (CID 673) XMSN Output Speed Sensor #2 (CID 2817) XMSN Synchro #1 Position Sensor
Check the coil resistance for Transmission Solenoid #1 If the coil resistance is out of specification, replace the coil. Otherwise, continue to the next step.

Confirm that both output speed sensors are properly seated in the XMSN case and the bolts are torqued to specification. Check the transmission clutch #1 valve for any
