May 16, 2008 (5:02 am)
I own a 2005 Chevy impala , 62,000 miles .........Now normally tranny problems come far down the road but mine is sometimes jerks a stop sign and after you drive your car for awhile you know how your car feels . Well it just doesn`t wind out right , shifting is different . So do I get it fixed $$$ which I can`t afford because the warrenty ran out or trade it in ? Suggestions ..........or any one else with these problems..?

take your car to a transmission shop that does free roadtest and diagnosis. have the car scanned i'd be willing to bet you will come up with a code 1811 maximum shift adapts. you have a 4T65E transaxle in your car and its very prone to this code

So does this cost and arm & a leg or don`t you know . Is this common ? Yesterday it was shifting hard between 2nd & 3rd , sometime it does it and then you don`t see it for a day or two . Thanks Fordfan .........

Well , got the tranny flush finally done . Nothing found , also no codes and the car really haven`t done anything abnormal in 2 months . Did take it in to get the oil changed at a GM dealer and they told me some things were going bad . Got a second opinion and found out that two of the four thigs they said were bad really wasn`t . Doesn`t that make you feel good ........
#114 of 477 2001 with P1811 code and intermittent harsh shifting
Jul 15, 2008 (12:34 pm)
I have an 01 Impala (3.8 V6) with the same issue mentioned in this thread, hard shifts with a P1811 code stored. 112,000 hwy miles, always been babied. Mine acts up when the engine temp gets to one peg under half or above, but never goes above half. It acts up the most shifting from 2nd to 3rd. It is also intermittent...some days perfect, other days hard shifts.
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?

as much as i hate to inform you the trans shop is correct about the valves. adding additives to this trans will do more harm than good the 4T65E transaxle is prone to this code. the definition is maximum shift adapts reached..what this means is the pcm in the car has reached its limit to be able to adapt the trans shifting pattern to keep it smooth......... please visit www.sonnax.com go to transmission stuff and search for your transmission in the locator....4T65E you will find that sonnax sells a replacement valve for your trans that corrects this problem. along with many other valves that help to restore oil circuit integrity within the transmission.....all of todays transmissions have major valvebody problems. please feel free to drop by my carspace page and read my blogs on oil circuit integrity concerning todays transmissions...it might shed some light on your situation
#116 of 477 2001 Impala LS Transmission Rebuild
Sep 27, 2008 (7:07 pm)
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!

I've seen a lot of questions on here about the same problem but no one posted what they did to get it fixed... Can someone send a reply of how they fixed the problem and how the car is running now?
