Where you located? Are you looking to get your full 2K back?

You really should post an ad in the Private For-Sale classifieds section of the forum - you'll have MUCH better visibility there. Just make sure to include your location, the price and a picture (they are the general rules for the "For Sale" section).

I have 158k miles on my '09 LTZ and I bought the car new. The original transmission still shifts perfect, no issues at all. I change fluid and filter every 45k miles. No flushing.

Following as well 2011 LS 165k Slip Bang shift

Car is new to me at 150k. Trans started doing the slip then grab shift from stop. Very intermittent but happens more consistent if roll and go (not a complete stop). I changed all the cars fluids as I want to know whats in it. Trans fluid was darker. Did the Doorman pan swap to add drain plug, new filter, added second magnet, re-filled with AC DELCO DEXRON VI. Two days later added one bottle of lucas trans fix (did not overfill it).

I have no code and it drives great on the highway. Should I have a shop scan it to make sure?

I am capable of replacing the solenoids and it seems like it can be done on the car. Seen a few kits on AMAZON. Any reccomendations?
Gotta have this car at least a few years as divorce really limits budget.... And its a good size/fit for me.

Thanks
William

No 1st hand experience with replacing the solenoids, but the TransGo shift kit was well worth the money. It doesn't make the car shift "harder", but shifts are much quicker than stock. A mild tune to increase the line pressure, change shift points and increase shift firmness also helps.

I saw that kit as well and watched a youtube about it.
On the Tune, can it be done thorough a scan tool at a shop? I do not have any scanner or tuner modules. I have seen mention of HP tune but I don't know what it is.

Slushboxes don't last forever. Between 150,000 and 200,000 miles is quite a lot. However you can probably get more life out of it if it's not slipping more than maybe 10% of the time.

These are symptoms of iron poisoned pressure control and shift solenoids. If you have the ability I recommend you change them.

Have you folks done the pan magnet TSB?

The other thing I'd recommend is a Magnefine transmission fluid filter in the return line from the transmission cooler loop in the radiator.
Change the transmission fluid and strainer in 1,000 mile intervals at least twice. This will get you down to a low concentration of 150,000 mile Dexron VI and get rid of a bunch of the filth as well.
Change the Magnefine filter every 1,000 miles three or four times to filter out the loose crud and catch any loose iron or til you get a reasonably clean filter then change it every engine oil change. This will filter the crud out of the transmission fluid without shaking a bunch of sludge loose like a machine would.

Pipe cutters will crack open spin on and inline oil filter cans without making a mess like die grinders or hacksaws. I picked up a Ridgid 4S at a yard sale for $20...

If it could I doubt a repair shop would.

Two popular tuners that can do this are:
Diablo Sport and HP Tuners

I have added the second magnet. Two new ones to be exact, onto my new Doorman pan with drain. I haven't done more fluid changes yet. Those tuner sites are a bit hard to understand. Can anyone who uses it share what they have? Estimated cost would be cool as well.

Cont... also, I went to the Transgo site and they only list 1997-2008 for the 4T65E... I checked Autozone and O'Reilly and they don't have anything. How do I know what to order/if it will fit?

edit... Website was weird, I downloaded the Transgo catalog and it says 1997-on. So I should be good.

Still looking at the tune option but...
Going to get the following from TransGo:
SK 4T65E
4T65-ACM

IF I ever drop the transmission I will also get 4T65-AFL. Will also replace valve body plates and solenoids. Only option after that is a rebuild or recon.

Thanks
William

Servicing your transmission on a regular basis helps. I change my filter and fluid every 40k miles. I never have any flush done, as it may force contaminants into the shift solenoids and cause problems like you describe. I have a 2009 LTZ with 180k miles which I bought new. Absolutely no transmission issues so far. It still shifts like new.

Slipping...

Sounds like his pump is shot. It's not as bad as you think. I don't believe in having a ratchet monkey do any service to your car if it's not necessary, especially transmission flushes. Half of the time even the filter screens they use are not as good as or even in spec with the OEM. I'd run her until the clutch pistons blow out their bore. I kind of like the chirp of clutches with their last 64th or two of meat on them, but I'm sick like that. A good guy can probably even get a set of clutches for it and smell his way through his spares and only charge you for the new ones he uses. Should come in under $900.

150,000 is a lot and line pressures should be checked, brown fluid does mean burnt clutches, but personally I would not screw with the t/b as a fix in that you would be lucky to get extra miles out of her with that. Get a new pump, get the planetary out, if it's not throwing codes, it should be good for another 45,000 after that. GL
