Estimate of cost for a timing chain replacement - 2003 Ford ...

if it is running then the timing will be ok. If not check that the cam shaft is turning as it may be a broken timing belt. A definition of the problem is a better way to get the information for what is wrong.

If you go to most car parts stores they will pull the code for free.

Depends on whether the Thunderbird engine is a V-6. it is a 4.0 V-6.and what year. Take your head gasket off the Explorer engine and place it on the head off of the thunderbird head, if all the holes line up its possible, check and see if the valve train are the same. Are the head bolts in the same place. And as you know, you will have to buy new head bolts to install the heads if they work. They say not to use old head bolt twice. They have been stretched and could break.

I hope this has help you on your project. Good luck.

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.

They had a lot of problems with the Mass Air Flow sensors in those.

Has anyone checked fuel pressure with a gauge ?
Is the check engine light on ?

its the solenoid pack in the transmission, the bushings are clogged, its an easy fix, there are multiple how to videos on you tube

I have the same problem! I also have 2002 Ford Escape and the radio/CD player just stopped while I was driving. It comes on when I start the car but goes off as soon as I put it into gear. My cigarette lighter (where I plug in my phone) also appears to not be working. This just started yesterday, so I don't have a solution. We've had a lot of rain here and my car has been outside. I'm hoping that something may just need to dry out. I'll post if I find something out. Please post any information that you've found!
