This article supersedes TSB 06-8-2 to update the Service Procedure and add Service Labor Times.
Some 2005-2006 vehicles with a 4R70/75E-W may experience an un-commanded torque converter clutch (TCC) apply or TCC partial apply immediately after the 1-2 shift. This may result in the perception that the vehicle lacks power or that the transmission is up-shifting too early. No DTCs are set during this condition.
Follow the Service Procedure for verification and repair.
Monitor (TCC %) solenoid command state - duty cycle and (TC SLIP ACT) torque converter clutch slippage - RPM, while in 2nd, 3rd or 4th gear with a TCC % reading 0.
If TCC % = 0 and TC SLIP ACT = less than 20 RPM then inspect the number 7 check ball (Figure 1) in the main control valve body for damage. Replace as required following the appropriate Workshop Manual (WSM) under Disassembly and Assembly of Subassemblies - Main Control Valve Body.
Figure 1 - Article 06-22-7
NOTE: THIS PROCEDURE IS PERFORMED IN 2ND GEAR AUTO (NOT MANUAL 2) MONITOR (TC SLIP ACT) AFTER THE POWERTRAIN CONTROL MODULE (PCM) COMMANDS 2ND GEAR AND BEFORE THE VSS READS 35 MPH (56 KM/H).
If you receive any other reading, this TSB does not apply and follow normal diagnostic procedures as outlined in the appropriate WSM.
NOTE: IT IS NORMAL FOR THE PCM TO COMMAND 4TH GEAR AT SPEEDS AS LOW AS 19 MPH ( 30 KM/H) WITH LIGHT ACCELERATION WHEN THE THROTTLE POSITION IS LESS THEN 20%.
