How dose a stall converter work in a ford with a c6 transmishion


The stall in a converter is when the internal parts of the converter lock and has the same rpm,s as the engine. Transferred to the transmission input shaft. Factory is 1000 to 1500 rpm stall. Put another way. You have a 1500 stall converter, when you floor the gas pedal and the rpm,s go to 1500 real fast, the rear tires will spin faster than the vehicle is going. Don't put a larger stall in a vehicle that isn't built to take the torque. Ie.. Upgraded engine, transmission and rear differential. Some thing will break.

Hi I have a 1994 v8 5.2L jeep grand cherokee with 285000km on the clock. The jeep starts every time first go and has no problem idling when started or at lights after been driven. The problem is when...


Sounds like clogged catalytic converter(s). You can either perform a 'back pressure' test to measure amount of back pressure in psi, ( 2.5 psi or more indicates restriction) OR, unbolt the pipes from the exh. manifold and road test and see if rpm / performance improves.

2002 ford escape v6 with trans code p1744 and 741


Unfortunately, the possible issues are numerous. The problem is most likely either your torque converter, or electrical issues with your transmission. Without knowing how the vehicle is acting, if it's drivable, when it trips the codes, etc, it makes it more difficult to accurately diagnose.

Here is what ford says about those codes...

SERVICE PROCEDURE
The torque converter clutch may not engage if one or more of the following conditions exist:
- Stuck converter regulator valve
- Stuck solenoid regulator valve
- Stuck bypass clutch control valve
- Stuck pressure failsafe valve
- Pump bore ring groove depth incorrect
- Worn pump shaft or damaged pump shaft seals
- Pump shaft internal sleeve loose (rattles)
- Turbine shaft seals damaged or missing
- Incorrect Torque Converter Clutch (TCC) solenoid
- TCC solenoid mechanically stuck or electrically inoperable
- Damaged internal wiring harness
- Incorrect gear ratio (wrong sprockets)
- Damaged or worn stator support
- Worn torque converter hub bushing
- Torque converter clutch worn or damaged
Use a scan tool to monitor the following PID's:
- TCC = Commanded duty cycle for TCC solenoid
- TCCMACT = Actual slip across the TCC, measured in RPM
- RPM = Actual engine speed
- TSS_SRC = Actual turbine shaft speed
- TCCRAT = Speed/Gear ratio of torque converter/transaxle

Hope this helps.

Why the rpm dose not go higher than 4000 rpm


The vehicle has a built in no load engine REV limiter to prevent damage to the engine from drivers who insist on "gunning the engine".
