Other powertrain problem on the 2005 Chevrolet Avalanche
Only 5 reports for this mode came with an odometer reading, which is too few for percentiles to mean anything. The page is here because someone linked to it; treat the figures as anecdotes, and see the full report for this year instead.
When other powertrain problem gets reported
There are 5 reports of other powertrain problem on the 2005 Chevrolet Avalanche, 5 with a mileage attached. That is too few to place the failure on the odometer with any confidence.
A part like this is normally expected to survive 92,000 miles. It is the 4th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 45,874 miles | — | — |
Read the 10th percentile as “one report in ten arrived this early”. Exact figures are shown in this table because it is the table of record; everywhere else on the site they are rounded to the precision the sample can carry.
What a percentile can and cannot tell you here
These five numbers describe the readings owners gave, in order. The median is the middle one: half the reports arrived below it. The 10th and 90th are the edges of the bulk of the distribution, and the distance between them is the part worth reading. A tight spread — say 70,000 to 95,000 miles — points at something that wears out on a schedule, and the schedule is knowable. A wide one, 20,000 to 190,000, points at a fault that hits some cars and never troubles others, which means the mileage on the listing in front of you tells you very little about your odds.
What these figures are not is a survival curve. Every reading here comes from a car whose owner filed a complaint, so the sample contains only failures: it cannot say what share of the fleet made it past 150,000 miles untouched, because those owners had nothing to report. Nor is the mileage the moment of failure — it is the odometer reading as recalled at the time of filing, which may be weeks later and is sometimes rounded to the nearest ten thousand by the person typing it.
Percentiles are shown at all only once 8 readings exist for the vehicle and mode. Below that the middle of a handful of numbers is noise wearing a decimal point, so the figures are withheld rather than dressed up.
What happens, and what it costs
Putting it right typically runs $400–$4,500 at an independent US shop. That range is an editorial estimate held in this site's failure-mode catalogue, not a figure from NHTSA, and it is a repair cost rather than a diagnosis cost.
The same failure on other years
The same failure is reported on 7 model years of this car. It shows up earliest on the 2003, at a median of 15,000 miles, and latest on the 2007 at 90,000 miles.
By volume the 2002 carries the most reports, with 11; the 2005 has 5. A mode that appears across most years of a model is usually a design choice rather than a bad batch.
If one year stands out to the left, that is the year to avoid; if the whole line sits at a similar mileage, this is wear rather than a defect in one production run.

What owners wrote
Verbatim from NHTSA complaint narratives, trimmed for length. The mileage is the one the owner gave.
7/13/03 - purchased new 2003 chevrolet avalanche vehicle from pierre chevrolet in lake city, washington 7/28/03 - reported sporadic loud clunk noises coming from transmission to service center of same dealer. Service center could not find problem and stated clunk noises were normal in this type vehicle. Noise problem continued and was reported but nothing was done and same service center normal clunk noise explanation was provided. 1/12/04 - took vehicle to todayschevrolet service center in bremerton, washington and insisted that clunk noise be thoroughly checked out. Received same "normal clunk noise explanation" and a manufacturer's bulletin numbered 01-07-30-42a stating the same. Could not complain no more. 4/12/05 - 21 months after the purchased of this new vehicle it had a total transmission breakdown in the middle of an intersection on a rural road. All gears except low gear went kaput. Because the breakdown occurred on a rural road where traffic is light, the breakdown did not caused a fire, property damage, deaths etc., but it had placed us in continual jeopardy. Although the transmission was totally rebuild, sporadic…
On january 8th 2012, while pulling out of the church lot we heard a clunk noise. The "transmission hot" display came on. We made it home at a slower rate of speed and eventually the light went out. I called gm customer service when I got home. They didn't have any suggestions, but just asked if I was towing something at the time and other questions to which the answer was no. I took my avalanche to the dealer the next day to get it checked. On the 9th, the service manager told me that 2nd and 4th gears were out. He said they would have to tear into it to find out if it could be repaired. I asked how much that was going to be and he said around $580.00. I let them tear into it starting on the 10th. Didn't hear anything on the 10th or 11th but on the 12th, the service manager said that the transmission was "pretty well cooked" and it would need replaced with a remanufactured transmission for $3200.00. He said the remanufactured one would come with a 3yr/100,000 mile warranty. I called back gm customer service back and left a message for them to call me. Based on everything I've read on the internet, it appears that this transmission…
Purchased may 31, 2005. 39 mileage. $43,000.00. 8 months later the transmission started jerking. We took it to the dealer 6+ times and they said they couldn't find anything. Now at 75,000 miles it won't drive in d it has to be in 3, 2, 1 to drive. I have read 100's of complaint about transmissions in 2000-2010 models. Gm needs to take care of their customer transmission problem or design a better transmission. *tr

How far this goes
This page is kept out of search results because 5 reports is not enough to publish percentiles from. It stays reachable because somebody looking at this exact car would rather see the reports than be told there are none.
Complaints are voluntary, so 5 is a floor and not a count of affected cars. Mileages are typed in by owners and cluster on round numbers. And the mode itself is assigned by software reading the complaint text, which is reliable in bulk and fallible one report at a time.
Questions this page answers
At what mileage does other powertrain problem happen on the 2005 Chevrolet Avalanche?
Across 5 owner reports that included an odometer reading, half were filed by 45,000 miles. A quarter were filed before — and a quarter after —. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is other powertrain problem on the 2005 Chevrolet Avalanche?
5 reports have been filed with NHTSA, about 0.1 per 1,000 vehicles. Complaints are voluntary, so this is a floor rather than a count of affected cars.
What this is and is not. These are the mileages at which owners chose to complain to a federal agency, which is not the same as the mileage at which the part fails on every car. It skews toward failures that happened outside warranty, cost real money, or frightened someone. It is still the only public dataset that carries failure mileage at all, and the shape of a few hundred readings is informative even when a single one is not.
