Well I figured I'd add a thread to the list of all the other threads about this all over the internet.

Problems:
o Bad hesitation on shifts, especially 1-2
o Slam/bang shifts (x5) from start or low speed takeaway.
o General odd, malaise behavior overall

I've had the transmission serviced every 30k miles and was due for #3, but a recent fiasco with attempting to replace this car with another daily driver has left me with needing this car to provide me reliable transportation for at least the next year/15k miles.

So I took it to a local transmission shop to have the Sonnax Sure-Cure kit installed and potentially to have the entire transmission rebuilt if necessary. After test driving and pulling the pan, they opted only for doing the valve body overhaul.

The car now drives and shifts like I would expect it to, but never did.

Out the door price was $1,600 about $1k less than what I was expecting for a full on rebuild.

All of those problems can/usually are related to bad solenoids. My 04 did it all, I spent ~$215 including parts and it has ran great ever since. These trans are notorious for failure though.

I hope this is all I have to do. The only thing my trans does is hardshift occasionally.

Mine did that for years before it finally decided to crap itself. Just drive it until it becomes a burden, then seek the repair job.

Yeah, but simple solenoid change should be cheaper than a rebuild. Although it's had the same black fluid in it since 2008 when I got it so it's probably already toast. I wonder why these trans suck so much. Almost as bad as the Turbo 200. Crying or Very sad

Before 03...cheap parts such as non-heat treated output shaft. Before 00 the 4t60e was vacuum controled, 00 was the 1st year for electronic controlled 4t65e. My info may incorrect. However, by 06 the trans's should have been indestructable, but failures after 100k are I guess acceptable. However, as said above all you need is 200 bucks and some time.

It was $146 for labor. I had planned on doing it myself because there are plenty of how-tos out there but it got pretty bad before I had time to tear it all down. Occasional slow shift and then it started shifting really hard, shaking the whole car. Thats when I said to hell with it and brought it to my usual guy that does my inspections.

Mostly correct. I believe they started being electronically controlled in at least as soon as 97.

Not sure if the 4t65e was used in cars other than w-bodies, but at least for Grand Prix's, 97 GT's were still the 4t60, while the 97 GTP's had the 4t65eHD. All GP's after that used the 4t65e with the HD version in the GTP's.

In 03, the valve body was changed. Also, the 4th clutch shaft was hardened. (this is where I may be incorrect)

That's not too bad.

Yeah just the solenoids. I had them all replaced while it was apart. The bad solenoid(s) did not cause any DTC's so dont let the shop say that isnt the problem when it is very likely the problem. I would recommend bringing your own trans fluid to make sure the right kind is put back in. I would also have them do a transmission filter change but do NOT let them do a "pressure flush" on the transmission, only a drain, filter and refill.

I agree on both counts. My rebuild was acting up without throwing codes so the shop was hesitant to do anything until I forced them to watch videos of what it was doing. I also found out they put in some random universal fluid in the first rebuild that is not Dexron VI (they went with GM fluid this time around...).

If you only have 10k on the rebuild, it should still be under the warranty. Most places (at least around where I'm at) have an pretty good mileage warranty after a rebuild, I want to say 3 year unlimited mileage, but I could be wrong.
