I have a sneaking suspicion this might be my next ordeal .... :nonod:

This is technically the second time it let go.

 

About a year ago Justin picked up on some slippage and we started detuning to make it live. It didn't and I had the 4L70 rebuilt.

 

About two months ago it didn't give me a warning. I was pulling my trailer unloaded and 1-2 shift went Booooom. Felt like I had been rearended.

 

This time, I fixed it the right way. jakes Performance 4L80e. This should handle anything I'm throwing at it.

That's the very thing that's kept me from doing any mods to this thing, aside from a plug-in tuner, cat back, and cold-air intake. If I lose a tranny, this thing will be down a year before I scrape up the funds and time to do it.

 

As it is, at 86,5xx, I'm starting to notice a sluggish initial 1-2 shift with occasional slippage. Only a matter of time I guess. :shakehead:

Any increase in trans temp before the big boom?

The first time, yes. Two months ago, no. It seemed perfectly fine. No soft shifts. No apparent slipping. Just a boom. I suspect a sprag, but I didn't tear into it to find out. I was just done with the 70. Jakes had a good enough deal on the 80 that it wasn't worth the little saving to rebuild the 70 and still not have any where near the trans of the 80.

The 09 I had started slipping from the 1-2 shift around 30k miles. Dealer looked at it, claimed they fixed it, but it still slipped just not as bad. After that it went down the road.

GM should sell us trucks minus the driveline, like the over-the-road truckers do. We'd certainly get alot more life out of them, and alot less headaches!

I always thought it would be awesome to have a Silverado with a CAT in it. Haha!

Changed brakes on a 2007 range rover sport. Front brembos are easy

Called around some more about a new rear window. Cheapest I found was Safelite. $216.13 total. I don't have to do anything or go anywhere plus the window is already tinted privacy tint so I don't even have to get it tinted. I took that deal.

      What have you done to your K2 today?

      By UrbanRage · Posted

      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.

      Vehicle Payments

      By ChristopherDobson · Posted

      Monthly payment is only part of the equation. With today's prices and interest rates, I'd look at the total monthly cost: payment, insurance, registration, fuel, maintenance, and expected repairs. A vehicle that fits comfortably into your budget is usually the better choice than stretching for a higher trim. I've also kept my vehicles longer over the past few years. New cars have gotten expensive enough that driving one for 10+ years, while staying on top of maintenance, often ends up being the most cost-effective approach.

      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.

      cam upgrade in CA

      By davester · Posted

      apparently CA smog is (or at least was)  checking that the vehicle is using the oem and/or a ca smog approved tune, so I expect you'll fail inspection doing it.
