I do, that absolutely is clear.


I've asked them to send me the error codes they said they were seeing, as well as any graph outputs that would aid me in making a decision.

I also got a second opinion, and to change those two components, the cost was almost equal between the dealer and this other shop, which is apparently highly reputable. $5k is the amount.

FWIW, a new transmission is $13k, from the dealer. The transmission shop I spoke to that gave me the second opinion, stated that it's difficult if not impossible for THEM to do a rebuild because they just don't have the experience with it.
WOW! That is ridiculously expensive. I see your point now. The automakers have been working hard for years to fine tune the "bending over a barrel" process......it seems that with the current newer generations it is starting to be accomplished. I'll stick with slightly older stuff with a 6 speed. I'm stuck with an 8 speed too, but thankfully it has been quite robust.

Best of luck buddy.

Wow...well, they don't call it the stealership for nothing...Too bad you're not in Vegas otherwise I'd offer to overhaul your transmission for cost of parts just so I can learn them and put videos on my channel...I'd go through the entire valve body diagnosis procedure mentioned above then tear down / inspect the case so we know if there's any damage or wear to soft parts and to what extent, etc...

That's a very, very kind offer! Though I'm not sure how I'd do such a thing, unless I ship my truck to you. I can't afford to take a road trip at the moment, and am currently without a vehicle. Truly stuck in a pickle, so to speak. :(

Update: I found another very reputable transmission shop in the area. I actually spoke directly to the tech who does the transmission rebuilds. He imparted ALL the same knowledge that @NickTransmissions did, which was surprising. The unfortunate thing is that the cost of rebuilding the transmission, he said, is $11k, but that is an extreme last resort, and he would not recommend it unless his diagnostics show that it was required.

I'm going to take my truck away from the dealer, drop it off with him, and have him do a proper diagnosis. Again, fun thing is how he stated he would do diagnose the issue, valve body included, was exactly the same as @NickTransmissions said he would.

I forgot some more info. We spent some time and talked rebuild. He stated that if we were to do a rebuild, he would rebuild with UPGRADED AND HARDENED PARTS, so even if I were to go with a new transmission from the dealer, I'd be back at this point no matter what again. I thought that in and of itself was worth it.

$11,000 for a trans rebuild. God help us.
Tell me about it. This inflation crap is seriously getting out of hand.

It was very very refreshing to talk to an actual, knowledgeable person. We'll see exactly how this plays out. The tech said he should be able to give me a definitive diagnostic in no more than 2 days tops.

About 1/5-1/6 the median US salary just for a transmission rebuild. How much does a quality OEM or better rebuild kit cost? And how long to rebuild? Sure, pay the tech $200 an hour. How does that add up to $11,000? The local Chevrolet dealership hourly shop rate is $179.95.

I'll be sure to ask.

What about a junk yard trans from a low mile wrecked truck? Would that be a cheaper option?

Update: heard back from them. They said the torque converter needs to be replaced, but they will not do it unless they do a rebuild because the clutch pack has potentially sent worn material through the transmission.

The problem now is the price. They said they want $11k for the rebuild. I asked them to do a full breakdown of the components price and labor, because that cost is just freaking ridiculous. They will get back to me.

Just for kicks, I checked how much it would be to ship my truck to @NickTransmissions to take him up on his offer, and that itself is ridiculously cost prohibitive. $4k one way.

They got back to me again, and spoke to the tech. Once again, no details given. He stated that the only way to actually determine what is wrong with the transmission, is to take it apart. At that point, he would only do a rebuild, and would determine what is actually bad, so it would be less than $11k, but that is the figure he gives to start with.

I still feel it is inflated, and I am nowhere past where the dealer was with respect to actual diagnostics. I've checked around, and everywhere is priced ridiculously, or don't know this transmission well enough to even want to service it.

I have no good options now. Some advice or help would be great.

1. Pay $4k each way to have my truck shipped and have @NickTransmissions take a stab at it. Be without my truck for a very long time. $8k + parts.
2. Pay $2300 for VB, $2700 for TC if that doesn't work, and still might not fix the issue. This is the dealer.
3. Pay $11k for transmission rebuild. 3rd party.
4. Pay $12k for a new, factory transmission. Dealer.

The sad thing is that the most attractive option is to throw a valve body at it and see if it fixes the problem. $450 (after core return), fluid and a new filter.

FWIW I don't think @NickTransmissions would do the R&R; you'd need to have your tranny pulled and get it to him. He can clarify. Obviously shipping would be less $$ for just the tranny.

I may have missed it, but have you thought about picking up a used tranny to have rebuilt while you continue to drive yours? Just a thought for an option.

Spot on - I don't do any R&R, just bench builds.

Plus, @jyi786 would have to be in Vegas for me to work on the transmission since I don't do any out of state builds on transmissions that require any sort of fast adapt relearn or are still not familiar to me.

I did. I looked around and found some 10L80s, but shipping makes it not worth it at all.

@NickTransmissions, if the clutch pack in the TC was actually going bad, would/should I expect to find metal shavings in the pan on the magnet?
