    Default Trailblazer won't go.

    My wife called today. Anyone have any thoughts?

    She backed out of the driveway, went forward to the stop sign. Everything was fine. When it was clear, she stepped on the gas and the engine revved without going into gear and going forward. Then she took her foot on the gas (I guess) and tried it again and it started to go.

    Anyone have any thoughts? It's the second time this has happened in 1 week. I've not had this happen to me when I'm driving.

    I guess asking if tranny fluid is low would be a silly question?

    Ususally when tranny is that low, torgue converter makes a heck of a whining noise?

    ALSO, the Change Engine Oil soon light has some on.

    I'll look at the tranny fluid tonight.

    Looks like there are some issues with the Sun Gear over time. GM maybe has given some people a break on repairs.

    Check colour and smell on dip stick when she gets home...I don't like where this could be headed.

    Hmm, maybe a 4L60E issue on some of the 2002 TBs? I'm gonna flush the tranny fluid and check for metal grindings, etc. Looks like there are some reports of a sun shell spline being made of substandard materials in the 2002 model.

    I read that the GM repair instructions for the sun shell for the 2002 Trailblazer (GMC Envoy, Olds Bravada) basicly say that it can't take the transmission heat causing it to strip. From 2003 on, GM built the transmissions with a "more heat resistant material" which reduces the likelihood of this happening.

    I'm not certain that this is the cause, let me look into it and maybe it's just low on tranny fluid.

    You may want to reboot the ECM too. Unplug the battery and see if there is any change in the condition.

    The Transmission fluid was fairly low. I drove it around the block and let it idle in the garage for about 10 minutes, the tranny fluid read in the middle of the "cold" zone and was nowhere near the "hot" zone of the stick.

    How much fluid does this bad boy take? For tonight I'm going to add in maybe 1 qt of tranny fluid, but what's the capacity?

    That is not low enough to cause that kind of grief. Thats about 1/2qt down just add little bit at a time so as not to over fill. Than let idle and retest. I'm not sure how much tranny fluid they hold.
