I took it to the local trans place and they said that just changing the PCS tsb 0O-07-30-002B doesn't usually fix the problem. They recommend following the new 2008 TSB 08-07-30-002 for reconditioning all the valves. None of the known codes listed in this bulletin show up in my computer, I only have the P1811 code. So I am wondering if they are just trying to take me for the extra money.
I have recently had the transmission flushed and the filter replaced. We add Sea Foam to the new fluid and its shifting a lot better, only a minor harsh shift now and then. The reason we did this is another trans shop told us that if the codes mentioned in tsb 08-07-30-002 are being stored, your trans is already on the way out the door so you will be sticking $750 (to have the valves reconditioned) into something you are going to have to replace anyway in the near future.
The first trans place is telling me if I don't have the valves reconditioned and just the PCS done, that I am going to ruin my transmission even if it feels like it is shifting ok. Bill will be $750, which of course I don't have.
Can anyone shed any light on whether they have done just the PCS and not had to have the valves reconditioned? Did you continue to have problems?
Also any thoughts on whether the first trans shop is feeding me a line or if there is some truth behind it? Since it is doing it between the same two gears and not through out the whole shift pattern, should I be looking at replacing the clutch assemblies and not the PCS or value reconditioning?
Thanks!!
Other than the usual Impala problems that everone else had in the past, I do like my red Implala.
I had experienced a transmission shift problem for the last couple months. I drive 45 miles one way to work all highway miles. I do drive easy on the accelerator. The problem is most noticable at the 45 MPH shift. The shift acts like it is having problems deciding what gear to go in. The RPM gauge will jump back and forth causing the car to lurch back and forth.
If I push the accelerator down a little bit, it will downshift, accelerate to a higher speed (50 MPH) and then shift just fine.
Sometimes this happens at the lower gear shift point around 30 MPH, but much more noticable at the higher gear change.
I checked the Trans fluid. Fluid looked clear and no burn smell.
It progressively got worse, and not wanting a problem like this to cause a major problem in the winter, I made some calls to several transmission places and to a dealership.
After explaining the problem to each one, no one will give you any idea of what the problem is. Just bring it in, they say.
So I took it to a local ATRA transmission shop that was reported to me as a reputable place to go. They have been in business more that 25 years. I was told that this was a common problem with the Impala, but sometimes it is a simple fix.
I left it with them to look at. Received a call about 2 hours later stating that it was more serious than they thought and would need $340.00 to tear it down to make a more thorough check on the transmission.
I asked what my worse case scenerio would be. They said they would not try to guess at this point. I approved the tear down.
Received a call a couple hours later and was told that the transmission needed to be rebuilt. Said the cost would be $2475.23 with tax.
The breakdown is rebuild transmiision = 1073.63, converter = 241.88, filter = 9.14, ATF = 24.50. Labor = 910.00, flush cooler = 65.00, tax = 151.07.
I asked if it would be cheaper to put in a brand new transmission. Was told that I would have the same problem again, because it would be the same transmission that I originally had. Said the rebuild will have better parts put inside than what the new one comes with. The rebuild comes with a one year warranty and is covered with any ATRA transmission place nationwide.
So, car is working fine, shifts well, the people at the shop were clean and polite. The shop was in good order. I do not know if this is a good price or not. Just wondering if anyone one knew.
I have read on this forum that several people have been having transmission problems also. I am 59 years old and never had a car with transmission problems until now. I do not abuse my cars and usually run them up to 200,000 miles plus before buying another.
This is frustrating and irratates me. I was driving a Chrysler LHS with 195,000 miles on it before I started to drive my wife's Impala. We were looking for another car for my wife, a Chevrolet car, Impala, Malibu or other to trade the LHS off or sale it outright as I usually do.
So what did we end up buying? A Honda for the wife and I am hoping I can drive the Impala another 100,000 miles. Then I have to drive the Honda. Come on GM! Whaaaa!

Who is up to joining me in class action against the 3rd party transmission supplier & perhaps GM?
I buy American products but with this performance I'm not sure how long I can hold out given the economy and the need to get good "lasting" value for hard earned money. Now is the time to demand better of our American companies before the remaining consumers bolt for foreign vehicles!
Also at 90 mph you aren't going to get good gas mileage anyway, so forget that.

Still... 17MPG... that sucks, I am pretty convinced I bought a car w/ no Overdrive.
The only issue is that when it's good and warmed up, the automatic transmission makes a low whining sound when its in 4th gear. If I downshift manually to 3rd the whine goes away. If I shift back to D, it starts whining again as soon as it upshifts into 4th.
It does not slip or seem to misbehave in any way, but I'm afraid to take it on long trips for fear that it's going to go out on me, and I'll be stuck with a 3 speed.
Any ideas? Or should I just drive it until something happens?
Thanks, B Dear
Does anyone have any suggestions?
now @ 75000 kilometers/45000 miles transmission periodically is slow shifting into reverse then engages hard and there seems to be a shift flutter from first to second you mention class action i would like more details before i have transmission inspected/diagnosed/repaired. please reply
Purchase dealership replaced the original tranny at 12K miles due to first gear slip.
Same initial slip problem became bad again at 49K. Took it to a different local dealership this time around and gm decided to replace the whole tranny again. (warranty is 100K on drive train in 07). Two days later same slipping from a stop. I took the car back and tech drove and recreated the problem. He said that the prior tranny was replaced due to a stripped 4th gear (not even the reason that I took the thing in).
One week later, gm is sending the now 4th tranny to be installed into this car. They tore down the new one (#3) and cannot find what part of the new one is failing. (I don't think it is the transmission, it seems like it must be something else - computer etc., but I am just guessing) Local dealer was supposedly working with gm's technical support to get this resolved. Will see what happens when #4 is installed.
Only other issue is ISS. I paid out of pocket to replace that when tranny #3 went in at 49K. ~$250 dealer did the work.

Please help!!!
I am suggesting we all do the same. If the new GM is going to emerge from bankruptcy on top, they must learn to address these problems and not ask us to accept them.

I too have read all the complaints and wonder what people are talking about. I guess yourself my father and I are lucky.

TECHNICAL
Subject:
4T65-E Launch Shudder on Acceleration, Lack of Power After 1-2 Upshift (Inspect and Replace 4th Clutch Piston and Friction Plates)
Models:
2006 Buick Allure (Canada Only), LaCrosse, Lucerne, Rendezvous, Terraza
2006 Chevrolet Impala, Malibu SS, Malibu Maxx SS, Monte Carlo, Uplander
2006 Pontiac Grand Prix, Montana SV6, G6 GTP
2006 Saturn Relay
with 4T65-E Automatic Transmission (RPOs MN7, M15, M76)
Condition
Some customers may comment on a low speed shudder upon acceleration, usually in the 0-32 km/h (0-20 mph) range. The customer may also comment on lack of power after a 1-2 gear upshift.
Cause
The cause of this condition may be due to a binding 4th clutch piston.
Correction
Inspect the 4th clutch piston, the seals and fiber plates. The plates may show signs of excessive heat in the center of the plate. The fiber plates may also show signs of heat in the adjacent area. Normal plates are heat treated and have a slightly dark appearance.
Replace the 4th clutch piston, seals and fiber plates as necessary. Refer to the Transmission/Transaxle section of SI.
