Pronstar’s CA adventure

[brashears9567]

Yeah they’ll be paying.

But they first need to tear-down the tranny, diagnose and approve the repairs, before they approve the rentals.

In the interest of our sanity and keeping this trip moving, I’m not waiting around…

So I’ll be hitting them up about it toward the end of the week.

Sorry to hear about the bad luck. But lol at tear-down the tranny.

You should rent a Toyota Sienna XLE. You'll never buy another Suburban lol

You should charge your phone.

Damn it! Lol! I never would've thought to look at that.

It’s the 6L80 6-speed.
It basically replaced the 4L60.

It’s been around for a while and the main shortcoming - shitty torque converter - is front and center. It starts to go, fills the case with crap, clogs the pump then failure.

I posted about replacing it in my Silverado about a year ago. That truck is not under warranty, and once I noticed something was amiss, I put a new torque converter in, before I was on the hook for an new transmission.

The suburban is under warranty and I’ve been noticing some slippage, but all I could do is wait for it to fail.

The new 10 speed is always shifting or looking to shift. It's about fuel economy not performance so it's always in too high a gear and when you need to go to the lower gear it always acts suprised and takes forever it seems. I've had it in 2 trucks and my expedition and absolutely hate it. There isn't much of a choice as it's in everything across 2 manufacturers in trucks suvs and even the auto mustang I think. I couldn't even order a truck or expedition with a different transmission. Still, while I think they gotta fail early because of that it doesn't seem to be the case.

Sorry this happened to you. It sucks being away from home and the trip get interrupted like that.

That is the cell phone signal icon next to the wireless signal. At least it is on my phone.

I have a feeling the crappy tow/haul mode that I experienced, was due to the torque converter being on its way out.

Yeah this trip has been a doozy…I just want to get home if I’m honest.

 

[PDiddy]

Safe travels. Hope you get it all sorted out.

 

[Army 1911]

That wouldn't have happened if you were towing that boat with a Prius.

GM, ever chasing that supposed pinnacle level of low NVH, has calibrated the converter in that model to slip. Going from memory, so I might be wrong on the numbers, but I think it's up to 15 rpm for quite a bit of its operational range. The converter is loose enough to need the lockup clutch to keep it under 15. Add in towing, especially if you weren't using tow/haul mode? I think even in manual mode (which I don't know if the 'burbs have, won't guarantee lockup in anything but like 7th gear?

In reality the 6L80e/6L90e itself isn't horrible. The calibration and the required converter to support it, are hot garbage. If you swap in a Circle D converter and tune out the slip, you can run a LOT of power through them for a very long time.

So we made it down in Mission Beach.

Minivan packed tight, we left a bunch is stuff at Mrs P’s aunts house…no room.
We will grab it on the way back, when we swap the minivan for a suburban.

Weather is crappy, low 60’s.
but we got a good parking spot and life could be worse…

Why do they do that (the 15 RPM?) Just to make the shifts smoother and wear out the clutches?

Glad you made it, semi, safely.

Been there a crap load of times. You will get the worst sunburn of your life in cloud cover like that.

I’m pretty sure it slips 50rpm to smooth the operation when it drops cylinders for fuel efficiency.

I can’t find anything about lockup strategy otherwise, but I know it wouldn’t lock in 2nd…there’s a steep grade heading out of El Paso and I wasn’t able to hold 3rd…tranny temps spiked to 255 degree by the time I got to the top. I’m positive that hastened it’s demise…

Maybe it was trying to lock but was unable to.
But holding 3rd or 4th for most of the drive kept temps down to the 200-degree range.

My buddy’s squadron had a perpetual lease at a nice place about a block away from the coaster, pretty much where we are now.

I was living in Orange County but drove down often.

It was good times back then, lots of great memories.

Stetson loves the sand…Rowdy just wants to be warm while eating roast beef LOL

Is that a booboo on your big toe?

If you love tacos, check out Rubios. They have 2 in the Mission Bay area (at least they used to)

You're welcome.

I was wondering the same thing. Except my question would be...Why is your big toe painted red?
