My parents have got a 2007 Saturn VUE AWD V6 with 17,000 miles on it. For the last couple months it's been making odd shakes and vibrations. They've taken it in a few times complaining of it but Saturn can't ever replicate the problem. It's gotten progressively worse over the last three or four months and finally, this past week, Saturn recognized there was an issue. They kept it for the day and decided that the torque converter is going bad and needs replaced. My question for you all is how much extra wear and tear has the transmission or powertrain had on it since the torque converter has been slipping for four months straight? Saturn is going to warranty it and repair it but how will longevity out of the transmission be over the life of the vehicle? It's extremely doubtful Saturn will do anything in that regard but the thought is, we can sell it while it's still worth something and get something else if it'll be an issue.

 

Thanks in advance, fellas.

I can see where it could effect the transmission, but I also think that the drive train will be fine if the torque converter is the problem. I don't think the TC slipping would create vibrating and shaking, I mean when it is disengaged you simply spin more RPM than when it is engaged. If it truely is slipping that is generating heat which isn't good. Really..who knows..only time will tell.

A bad TC can certainly cause a nasty vibration/shake. Haven't you heard about the Tundra's TC issues? They are replacing those faster than they can make'em.

True, I thought I read somewhere that he thought it was "slipping" His shuttering problem can come from several things, like overheated trans fluid, which is a possibility if the TC is slipping and making lots of heat, and a large cause of TC shutter is the TC lockup clutch having problems locking which is caused by low apply pressure which is supposedly an internal transmission problem, but that doesn't seem true if a new TC is the fix. IDK if the Tundra's just have junk converters or what :thumbs:

I just read an article dated late October of last year about the Tundra's problems. They were investigating the problem still, they knew the problem was the TC locking (or I should say attempting to lock) and having problems, but they didn't know where the problem came from. If the TC gets weak apply pressure the clutch is getting abnormal wear every time it tries to lock, which eventually would lead to a failed TC, so replacing it with a new TC would solve the problem..temporarily I guess. IDK, I drive a Silverado :thumbs: It's possible their TC plant made a bunch of junk converters.

Saturn is going to put in a new converter sometime next week and hopefully that'll take care of it. I question the longevity but I reckon my parents won't have it more than 5 years and the powertrain is covered until then anyway. Thanks for your input, guys.

      This is interesting. My quote tagged here is different from my original quote. After I’m driving them longer. That isn’t me. I don’t talk that way. I definitely wouldn’t express myself that way. Interesting.

      What have you done to your K2 today?

      I have the same running boards on my truck and I do agree they are bulky. I also find myself stepping over them when getting in and out of the truck. Besides providing protection to the rocker panels, they aren't very useful.  I will be replacing them soon with the Amp Powersteps.

      OCI, not when but why?

      By Grumpy Bear · Posted

      10 Ford and Chevy engines proven to reach 300,000 miles   You may note a common 3K OCI on this list of gas motors. I skipped over the diesels. Dh'O.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By jake111 · Posted

      Thanks newdude!  By the time manual selection is needed, I'm probably too much of a control-freak to depend on the transmission sensing braking to activate automatic downshifting.  I would be anticipating the situation and already be manually downshifting.   This truck replaced a 2004.5 LLY diesel with the Allison 5-speed.  Putting it in T/H made noticeable differences (when the torque converter locked, upshift points, downshift behavior).  On this 2024 gasser with the 10L1000 I haven't been able to detect much, if any, difference.  Ok, I can never tell now when the torque converter locks up.  But I also don't notice differences in shifting.  For downhills, I've probably already manually downshifted by then anyway.  Since it's also more awkward (than the 2004.5) to engage/disengage I don't even bother.  Or maybe it doesn't really matter with just a 3k lb. camper in the bed?   Thanks also for the list of reasons the charging system might select various voltages.  However, what I am seeing doesn't fall into any of those categories.  It very definitely, and very consistently, rises after coasting/braking.  Maybe not immediately, but not very long after coasting/braking.  Very consistently drops voltage when no longer coasting/braking.  It might also be interacting with the camper battery charging (I might disconnect the camper and see if it changes the charging behavior).  I also need to recheck turning on headlights for when I want to force it to charge the camper.   Another JR, in June I converted the camper to LiFePO4.  Since it's not a good idea to try to charge lithiums directly using truck, I installed a Victron Orion XS DC-DC charger (which BTW is AMAZING!!).  Being cheap, I only had to buy that one item (besides the battery, of course) to do the conversion.  The camper OEM 120v battery charger (only 19 years old and works perfectly) and the truck feed the input to the DC-DC charger (not at the same time).  But I didn't want the camper charger feeding back to the truck so I kept the old separator.  I considered replacing the separator with a 30amp diode but that means more work and might add another 1/2 volt drop.  One thing that surprised me was the voltage drop over the long 10awg wire run, so I can only charge smoothly at 8 amps (because the DC-DC charger is completely configurable).  Another reason I don't want an added voltage drop with the diode.  I might also be a little lazy but all this work is being done under the sink with a small cabinet opening.
