Transmission life expectancy

I have an '09 LTZ with 3.9 engine and 4 speed auto transmission. I am at 134k miles now, bought the car new. I have changed transmission fluid and filter every 45K miles so far. No issues with the transmission yet, but I am worried about longevity of these as they are not the most robust units out there. The car resale value has depreciated to the point where it is cheaper just to drive it until failure and then throw it away or maybe install a rebuilt transmission? How many miles can I expect out of the original transmission assuming fairly conservative driving habits?

Ive seen multiple units with 250k on them, and no signs of stopping. I have however also had to rebuild units with less than 10k miles. What youre doing seems to be working. Dont change, dont stress.

i have 160k on mine so far. i will note the past 5-10k have had a bit of an issue with the slip bump on take off randomly. seems to be more so when i do only city driving, after doing a 4 hour road trip it seems to happen less than it had in the past few weeks. i'm in the same boat, if it fails outright i will probably just have it rebuilt and continue driving it. no rust in the car and motor is solid. plus no payments/future challenger scat pack are the main reasons lol.

I have 123 000 kms on mine and it is slipping and banging into gear. I'm thinking of trying some Lucas tranny repair and see what happens?

Check DTCs to see if it has P1811 stored. its very possible you just need a pressure regulator solenoid

My '06 with 310K on it is having the tranny replaced this week. The past few months have noted slipping, and the torque converter is starting to exhibit signs of weakening / failure. The pressure solenoids have also been providing the clunky starts once in a while as well, but with 310K, these issues are to be expected. The new (used) unit with 57K on it, is being provided with a 3yr / unlimited mileage warranty, so I expect to have it go at least that long.

If more people serviced the trannies like you do, there would be longer life out of their transmissions. Good job. Though I'd recommend the flush every 30,000 miles. More frequently for people who own vehicles that have CVTs on their vehicles.

Don't flush the 4T65E. Just change the fluid.
If you don't have a Magnefine filter installed... replace the strainer.

Let's not forget the benefits of an auxiliary transmission cooler - they are NOT just for trailer towing or "severe duty vehicles" (e.g., police, fleet, or taxi). Excessive heat build-up is a major contributing factor to transmission failures.

Yup.
The stock radiator loop cooler will only pull the trans temp down to the engine coolant temp... at best... 210F is to darn high.
Ideally, for long life, you want to see trans temps in the 160-180F range.
