Automatic Transmission - VT25-E
Manual Transmission - Getrag 5 Speed

Stays in Reverse
Checks
Action
Manual valve (202)
Inspect for wear, sticking or binding. Replace the manual valve (202). Refer to Control Valve Body Assembly Disassemble .
Control solenoid valve assembly (201)
Inspect for contamination with debris. Replace or flush the control solenoid valve assembly (201). Refer to Control Valve Body Assembly Disassemble .

Your best bet , take it to a qualified repair shop .

I have been getting the code p0740 it says something about the torque converter clutch circuit. it doesn't seem to be going into over drive. dose anyone have any suggestions I can try.


On some cars, there is a TCC solenoid in the transmission which can be replaced by removing the bottom pan. In some cars this solenoid can't be accessed without major disassembly.

A/c is not working, was told it was a module or something on the heater box, would you know what they are talking about and how much to fix?


Without knowing any specifics, it sounds like it is the climate control box, which is a valve that diverts the air flow over the heater core to give you heat, then when you want air conditioning , a valve moves a baffle to divert the fan air to pass over the A/C evaporator coil located in the car cabin.

The bad news is all this climate control valves and mini radiators are underneath the dash and there is a lot of labor getting the stuff out, especially if it needs replaced. You might luck out and it is just a linkage rod became disconnected. But count on at least 500 bucks if there is disassembly needed

Locate vacuum modulator chevy trailblazor 2003


Please verify the year of your truck. A 2003 Chevy Trailblazer has a 4L60E transmission. This transmission does not have a vacuum modulator valve. The 4L60 uses a vacuum modulator valve but the last year for that transmission was 1992. The perpose of the modulating valve is to control/regulate line pressure. The line pressure in a 4L60E is computer controlled or controlled electrically.

I NEED TO REMOVE THE EGR VALVE


The Exhaust Gas Recirculation valve does just what the name implies: it diverts some exhau st gases back into the intake system at low engine speeds. This lowers combustion temperature to reduce NOx levels. It also reduces throttle response and bottom-end power.
Disabling the EGR valve is easy. Locate the valve and the EGR vacuum modulator valve (two gold-colored metal stampings, usually at the rear of the engine). The EGR valve has steel lines leading to it from the exhaust manifold. The EGR vacuum modulator has two vacuum lines between it and the intake manifold and a third vacuum (soft) line between the modulator and the EGR valve itself.
EGR Vacuum Modulator
EGR valve (arrow) is shown adjacent tosimilar EGR vacuum modulator valve. EGR valve is connected to exhaust manifold with steel lines. Modulator has vacuum lines only.
Disconnect the vacuum line between the valve and modulator and place any solid object of appropriate size (dowel, etc.) in the line, then reconnect the line. Or you can get a EGR block off plate

I need to change the transmission modulator valve on a 2003 Chevy Impala. I need help with the location of the valve and even steps on how to change it. Thanks


Hello, the 2003 impala's dont have a transmission modulator valve. this transmission is electronic controlled by the power train control module. the transmission uses a pressure control sol. inside the transmission instead of a vac. operated modulator valve. if you are having a late harsh shifting problem, this would be more in the area of a pressure control sol. at fault

I have a 1989 s-10.The parking brake light blinks six times,pauses then flashes again.I was wondering what trouble code that would be???Thanks.


RWAL Fault codes
Codes for Dodge RWAL, Ford RABS and GM RWAL applications are similar but have a few differences:
  1. Should not occur (replace the controller if it does)
  2. Open isolation valve circuit or defective ABS module
  3. Open dump valve circuit or defective ABS module
  4. Grounded or closed RABS or RWAL valve switch
  5. Excessive actuations of dump valve during ABS braking
  6. Erratic speed sensor signal
  7. Shorted isolation valve or defective ABS module
  8. Shorter dump valve or defective ABS module
  9. High resistance or open speed sensor circuit (resistance should be 1000 to 2500 ohms)
  10. Low speed sensor resistance (Dodge & Ford only)
  11. Open speed sensor circuit (GM only)
  12. Stop lamp switch circuit (Dodge & Ford)
  13. ABS module speed processor (Dodge & Ford only)
  14. ABS module program (Dodge & Ford only)
  15. ABS module RAM memory failure (Dodge & Ford)
To manually clear a stored fault code on GM and some Dodge trucks with RWAL, remove the ABS fuse or disconnect the battery for 5 seconds. Ford RABS codes will automatically clear when the ignition is turned to the off position.
