Engine Stalling On Engagement OR While Stopping

Engine Stalling

Engine Stalls While Stop


Ford/Mercury's Engine Stalling On Engagement/Stopping


Problem Mostly Noticed on  2005-’08 Ford Escape and Mercury Mariner ­vehicles equipped with a CD4E automatic transaxle and built from Aug. 1, 2004 through Feb. 15, 2007, may exhibit an engine stall when coming to a stop or when engaging the transmission into drive or ­reverse. 

This condition may be intermittent and often occurs after extended drives. There may be no diagnostic trouble codes stored. This may be caused by internal wear in the torque converter, which prevents it from unlocking.

How To Repair And Solve This Problem:

1. Inspect and repair all non-transaxle codes.

2. Monitor the PIDs (parameter identification) for TC_SLIPACT as the stall is occurring.

a. If the slip is greater than 20 rpm, the stalling is not transaxle related. Repair following PC/ED procedures for engine stalling condition.

b. If TC_SLIPACT is less than 20 rpm with the transmission in park or neutral, torque converter internal failure is the most likely cause, proceed to step 3.

3. Remove the transaxle assembly and check the rotation of the torque converter in the bell housing. A failed converter will be difficult to rotate.

4. Remove the torque converter, drain the automatic transmission fluid (ATF) and refill the CD4E transmission assembly using MERCON V ATF.

5. Install a new torque converter and reinstall the transaxle assembly.

6. Back-flush the transmission cooler system.

THIS SAME TYPE OF PROBLEM WAS ALSO NOTICED ON MAZDA'S

My 2005 Mazda Tribute is having a stalling problem. It is not consistent, but about every two or three days when I stop at a stop sign or traffic light the engine will die.

The idle air control valve needs to be replaced. Cleaning it will not fix this problem.

New Clutch Slips After Installation

Image
Adjustable Clutch Master Cylinders Clutch Slips If the clutch is cable operated then you might need to slacken the cable. Clutches are the opposite of brakes, as they wear brakes get slacker but clutches tighten up. If there's insufficient slack in the cable then this will prevent the clutch from fully engaging.  If it was slipping because you rode it, the plates would be glazed. Good plates would means that they did the job wrong. A greasy flywheel maybe. The pedal is stiffer because they used stronger springs when they did the job. If it's mechanical linkage, they might have left it too tight. poor job of replacing clutch assembly ,if  only replaced the disc and not resurfaced the flywheel and replace the pressure plate. Once they get glazed form slipping a new disc doesn't help very much. Look at your old receipt for the work, it should list the parts: clutch disc pressure plate pilot bearing throw-out bearing pressure plate job-out...resurface flywheel ...
