2003 H2 transmission


Our H2 is only 5 years old. We have it maintained every 3 months. What might have caused the transmission problem. I have to pay almost 3K to have it replaced.

    2005 H2 lost drive and reverse gear during acceleration.
    Could this be a solenoid problem or a pump failure?

    I think I have the same problem might have to replace the transmission. Infact I have really kept my H2 in a great condition with regular service etc... don't drive it much. I totally lost power and wont go from 1st or 2nd gear with high RPM. Any suggestions I am in europe we don't have a dealership in Romania.

What does a tuneup cost?


Why would you pay someone to replace an air filter?

There haven't been tune-ups in 25 years,only spark plugs
left from those days

You ask because you have never had that service your asking
about, done before on any vehicle?

I OWN A 2003 TOYOTA 4RUNNER WITH 60000 MILES. OVER THE LAST 6 MONTHS WE HAVE NOTICED WHAT SOUNDS LIKE A LOOSE BELT SOUND THAT LASTS FOR ABOUT 5 MINUTES AFTER THE VEHICLE IS STARTED. I TOOK THE CAR TO HAVE...


It is common practice to replace belts that are 3 years or older depending on the type belt it is. The stretch and break over time with heat and cooling that goes on. Some mechanics are not trained in the proper maintainance of belts and hoses You should be having the timing belt change to. I believe if it is the ribbed type belt it is supposed to be replaced at 60 thousand miles. If you don't and the belt fails it's a $3000.00 repair minimum so $200.00 IN maintiance is in my opinion worth it. And belts can just fail even new ones. However you could also have a Tensioner pulley bearing going out causing the problem so I suggest you try a different shop. Hope this helps and thanks for using fix-ya.

My 2003 h2 hummer will initally not shift from


Check the linkage that goes from the shift lever down to the transmission. It sounds like somewhere along the line, it has become disconnected or has broken.
if that parts are clean then It sounds like you have a shift control solenoid that has high resistance causing the hard shift you describe. Scan the PCM for trouble codes if none are present you could have a internal transmission problem.
