Question on transmission for 2004 Impala
I have a 2004 Impala base model, 3.4L V6. Love the car, great fuel econony, sooo comfortable on the highway, but, there seems to be a problem with the transmission. After driving for an hour or so, if I'm stuck in traffic particularly and am coasting between first and second gear, I find the transmission shifts every abrupty. The car literally jerks when it changes from first to second, and I also feel an abruptness to it when it downshifts from second to first. Doesn't seem to do it at high speeds, and it doesn't do it from cold start-off - its always like after an hour running. Have any of you Impala owners experienced this and can advise me what it is and what to do about it?
transmission is going bad. Have it replaced if you want it fixed. Otherwise ignore it, it could work another 100,000 miles before it stops working. you've checked your transmission fluid level right?
Yup, fluid levels are as they should be. You've experienced this? Absolutely no way around this?
Hi there I leave in Israel and I have a 2005 Impala bought 3 months ago. I noticed that when the geat is hot (hot I mean at working temperature) there are harsh shifts, especially noticed between 2-3 and 1-2 upward shifting. When the gear was cold shifts were all very smooth. I wasn't happy with those none-smooth shifts and I wanted to know if it means that the gear is in bad shape so I took the car to some repair shop that I know over here, just as I moved in and told the guy there about the problem, he answered immidiately that probably the pressure control solenoid in the gear is not working and should be replaced, he told me that a lot of Impalas suffer this problem (in Israel there is only the 00-05 version) and that the original GM solenoid is bad and the replacement one is made by Bosch. I replaced that solenoid in the repair shop and since then the gear shift are smooth as silk. :) You can get it here: http://cgi.ebay.com/ebaymotors/4T65E-EPC-Solenoid-Pressure-Control-2003-Up-GM-Volvo-_W0QQcmdZViewItemQQhashZitem4ced9b7b94QQitemZ330403904404QQptZMotorsQ5fCarQ5fTruckQ5fPartsQ5fAccessories There is also a transgo springs kit that is also related and deny such harsh shifts even if by chance the pressure solenoid isn't keeping pressure so correctly. http://cgi.ebay.com/ebaymotors/GM-4T65E-TRANSGO-SK-4T65E-SHIFT-KIT-T84165G-_W0QQcmdZViewItemQQhashZitem5641834bb9QQitemZ370466311097QQptZMotorsQ5fCarQ5fTruckQ5fPartsQ5fAccessories I know at least 3 other guys here with Impalas that had same problem, 2 replaced the solenoid and the 3rd guy replaced also the transgo kit. All are happy with the gear shifting. Replacing the solenoid is a lot of work, relatively but the trnasgo kit is easier. I suggest you to replace that solenoid first, it will probably solve your problem. Good luck
HI i have the same car as you and some what going Thur the same thing i have 215,000+ miles i been having it for 7 years now and this is the first problem i ever had from it do you think i should get a new transmission are get a new car. when it runs it runs then it seams like it jumps from D to N and stop pulling
To queenera9. Hi, I still have this car and I still have the problem. Other people on this forum here have suggested it is the pressure control solenoid. I've heard many people say this actually - I just haven't had it serviced yet. I have a friend who has a 2003 Impala same as mine and its doing the same thing to him. He has over 250,000km on his car and I asked him the question - he said he was told it was the solenoid, but his attitude is - I've driven it this far, just put up with it. I wouldn't say get rid of the car becuase of it, its still has a lot going for it. I'll probably get the solenoid fixed eventually when I can budget for it.
