SOURCE: when do i change the transmission fluid 2005 monte carlo?

Well, I'm not really sure what the manufacturer's recommended interval is... But to be honest with you, once every 100000 kms, or 5-6 years is plenty for a transmission fluid/filter change is enough (yes, there is a filter inside the pan of the transmission, assuming it's an automatic). But, if you notice problems earlier (transmission starting to slip, fluid discoloration, or any other transmission related driveability issues) the first thing to do would be to do a transmission oil/filter change as soon as you can. Beware of these places that offer a transmission flush, that's about as useful as putting winter air in your tires, and costs money for nothing.

SOURCE: fuel pump

The fuel pump is located in the fuel tank and can be reached by removing the back seat.

Be careful when you are disconnecting all connectors and watch out for the pressure of the fuel pump.

Good luck.

Engine light code p0455 chev monte carlo


Hello,The problem is that the EVAP system is not able to achieve or maintain vacuum during the diagnostic testThe control module tests the evaporative emission (EVAP) system for a large leak. The control module monitors the fuel tank pressure (FTP) sensor signal to determine the EVAP system vacuum level. When the conditions for running the test are met, the control module commands the EVAP canister purge solenoid valve OPEN and the EVAP canister vent solenoid valve CLOSED . This allows engine vacuum to enter the EVAP system. At a calibrated time, or vacuum level, the control module commands the EVAP canister purge solenoid valve closed, sealing the system, and monitors the FTP sensor input in order to determine the EVAP system vacuum level. If the system is unable to achieve the calibrated vacuum level, or the vacuum level decreases too rapidly, the PCM will set the code you now have.So, you either have a stuck open purge valve, a stuck open vent valve, a false reading fuel tank pressure sensor, or a cracked/broken EVAP line.

Check and see if there is not a vacuum hose dislodged, the vacuum modulator may not be getting enough vacuum and causing the "hard shift" condition.

I have a 1999 monte carlo with a 3.8L V-6. The check engine light did not come on; however, it is not shifting into overdrive and shifting rough when hot. Any ideas?


Hello,
You are experiencing the most common signs of the end of the life of the 4T65 Transmission that is installed on your vehicle. There are many ways to prolong the life of the transmission, however since you've already lost overdrive chances are your transmission is passed the point of being saved. Most 4T65 transmissions begin to exhibit this above 120k miles give or take depending on driving habits. Some have had success with replacing the solenoids and valve body, however chances are your transmission is need of an entire replacement or rebuild.

    If the transmission wont engage in any gear,there is a internal fault and will have to be rebuilt or replaced.We installed a used transmission this past year in a 1998 monte carlo.These days its more cost wise to install a used unit rather than buying a new one.
