    Default Rut roh...is there a tranny expert in the house

    I have a 2001 3/4 ton 2wd gmc....it hasnt moved for a few weeks..last time I went boating. Sooo I decided to driver her 2 work today. Going out of my circle and the first to second shift was WAY firm....bam. They are all to firm but 1st to 2nd and 3rd to drive was the worse. Another thing that may or may not be related the truck never got above 180....seemded to me like all summer it ran about 195.....think I should be worried about the 180*. It was 32* this morning and it never got real toasty with the heater.

    btw my comute is 22 miles and 35 minutes long
    For what its worth...my trans temp gauge barely moved .

    get sume seafoam trans tune and pour into it, valves in the valvebody are sticking and ya need to head it off before it gets worse. be carefull parking em for 2wks this time of yr, i've done at least 2k worth or ratdamage repair in the last couple weeks, they're beginnin to look for a warm place to chill this winter lol. if it does do it again, also try turning the key off and back on again jus for shits and giggles, that yr model truck was prone to ignition switch issues.

    Dare to be different, if it turns out great you can claim you planned it that way.

    I will the seafoam trans tune stuff. Damn...I was bleeding dollars this morning. I was happy the truck was happy at lunch time.lol
    Edit: well that was interesting...I just called the tranny shop I have used on and off for decades to ask them how much to flush my tranny. He tells me they don't do that because if there are any metal fileings in the bottom of that pan that the flush could put them back into the system. Any thoughts on that? Then he tells me 125.00 to drop the pan and put a new filter/fluid in. That sounds a little steep doesn't it....heck I can do that....I guess I will tonite before it gets ant f'n colder.

    That sounds cheap to do a transmission service, we charge 150-180 depending on if you have 4l60e or 4l80e. and yes do not flush your transmission, have normal service done. If anything is com ing apart it will be in pan.

    educated guess of being a mechanic for ever now..lol

    your governer valve hung up and increased your line pressure to everything reason for hard shifts

    i work for a national know trans shop and as for flushin high milage cars with new fluid is a no no we use saved fluid from cars with low milage on them as that way there is still clutch fiber /particales in it and will prevent the slip that will come if using new fluid sometimes

    The gmc trucks with a little lower than average voltage will cause your tranny to act up. Scared me once too. Put in a new battery and was good to go.
