ISSUE
Some 2005-2010 vehicles equipped with a 4R70/75E-W transmission 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. Additional symptoms of uncommanded TCC apply when coming to a stop (before the 2-1 downshift is commanded), are
engine stalling or lugging when engaging manual 2nd while at a stop and code P1742 may be present in continuous memory. However, the vehicle
should operate normally in park, reverse, neutral and manual 1st gear.
ACTION
Follow the Service Procedure for verification and repair.
SERVICE PROCEDURE
1. 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.
a. If TCC % = 0 and TC SLIP ACT = less than 20 RPM then inspect the number 7 check ball 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)
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 VEHICLE SPEED SENSOR (VSS) READS 35 MPH (56

KM/H).
b. If you receive any other reading, this procedure does not apply; 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%.

Mercedes-Benz ML63 AMG Reliability - 2018 Ratings

New AMG SUV is the first full-size SUV which has that two way of building combined. 2 separate 1/4 mile records were made by two separate RENNtech cars at Palm Beach International Raceway on Wednesday night. The C350 took everything up a notch, but again not a night and day experience, while the C63 is otherworldly, its power devastating, adhesion and correlating road manners unfathomable for such a solid, substantial four-door sedan. I took my girlfriend to an Italian restaurant in Austin, Texas that we had both wanted to try for a while. While the show car does not look anything like the current Impreza, equally Subaru insists the concept鈥檚 styling forms only a guide to the production WRX. The interior of this car has been designed to have an elegant yet sporty look that matches perfectly with the vehicle鈥檚 overall appeal. To get the power onto the road, the rear tires are wider than the front ones on a mid-engined car - usually about 30% wider. Also look for a return of the hybrid S...
