I did learn that if you push hard enough, you'll get good results. The main portion of the solenoid consists of an electric magnet made up of a coil of wire. Seeing how Chernmax beef up his tranny a few times, these tranny just werent made to hold more power if you decide to add more mods to the car. They will be able to tell you exactly what is wrong after an inspection and give a straight answer on what needs to be repaired. I can do most of the work myself. If anything has any adjustments to it, please measure it before you disassamble it.

The three planetary gear sets provide five forward speeds and one reverse speed. Does it sound like my entire transmission needs to be replaced? There are many great YouTube videos on the subject but most miss out some of the finer points of the procedure. The main problem with this is not knowing how to check and fill this transmission. I belive what happens is the valve bodies get crap stuck where the fluids flows to each solenoids which would cause the jerk. It is a trans axle designed to be used in front wheel drive vehicles. Jerky when parked and shift through gears from P to R, then again to D.

I have ordred rebiult vb and that did not work as well, it did make it better and shift different but the problem is still there after it warms up. How do I really know if I really need a new valve body. At this point, personally I would take it to a transmission shop or a specific transmission specialist. That gets worse as time progresses. You may need to install an entirely new valve body soon. The neutral relay valve controls the route of fluid into the forward clutch circuit. .

Some people have had success with this, but more than likely for the S40 anyway you will probably need a new auto trans valve body. Took it for a quick spin and was great. Generally, cars exhibiting valve body and fluid related issues are well past the 10 year 100k mile mark. It idles at a 5 and stays there when im going 60mph. This kit makes a world of difference. Later cars that are experiencing shifting problems could benefit from simply flushing the fluid, or getting a software update. We have had incidents where the person rebuilding the transmission and the person installing the transmission not talk to each other.

The best thing you can do is to remove the valve body as carefully as possible so you don't damage the gaskets. I am slowly but surely running out of options before I might need to scrap the transmission and install a new one. In your normal mode, shifting and lock-up occur at lower speeds to increase fuel efficiency and reduce fuel consumption. Changed broken engine mounts some difference. The only other problem I have besides that is a leaky vacuum air pump.

I wonder if you know who makes the Transmission for our cars? I question you, these tranny can make more than 350-450 lb-ft by any upgrade? This is a very good idea to do at this point, as 144k is about 3 times longer than what I would recommend. Stop in today or fill out the form to the right! I actually purchased the kit and left it with the shop owner to look over to see if he felt comfortable installing it. You could make a larger threaded hole in the transmission—say M17 in the main transmission housing and a smaller hole- M12 or 13 in the filter plastic so that you could install a plug on the filter before reinstalling the larger bolt into the main housing. Seems to be valve body problems, i had the exact seem issues too, i overhauled my tranny and went with a re-manufactured valve body upgraded with sonnax parts that also comes with the over sized boost valve. My questions — 1 Is it better to buy a rebuilt or an after-market or a Volvo valve body? I am honestly scared with all this situation and already regret the money I spent on the Volvo.

I would like to make a formal complain about the whole situation and the potential deficiency of this vehicle. The problem manifests itself as a hesitation, and then a bang when the car finally finds a gear. If you are already having slippage or banging into gear, then you should look at these options for a rebuild. There are lots of check valves, check balls and small filters. They drove for 40 miles and did experience the symptoms. You can see it here: I was told that this kit repairs the problem all by itself, but I got a little anal and installed far more new parts into the valve body.

What you do see real well is what looks like a fill plug figure 2. Not the same part number, jus one number difference, but will it work on 04-05 cuz the 06 trans usually dont have tranny issues like the 2 previous years. I guess you could say I have a new found love for my 6th gen and look forward to the many upgrade I have planned. Did you clear your cookies? They allegedly did the job n he says it feels better but still has the hard shifts. Any thoughts before I take it in for inspection? One of my boys is having tranny issues n he brought the kit n a lot of shops r turning him down for installing the kit.

The fluid is not exactly cheap, but it is worth it, and even at this price we have trouble keeping it on the shelf due to the order volume. You can install it without doing that, and besides if you unbolt the valve body, you may have to buy an entire rebuild kit just to get the new valve body gaskets which are not sold separately. This transmission has been on the road close to 15 years now. This took about 2 hours because it was often just a trickle and sometimes was not pumping at all I was using clear hose to drain and I could see that the fluid was struggling to get up the hose and into my container marked at 2 litres. It is designed to lock the turbine and impeller together at highway speeds. There are a lot of people out there that have had the same problems. And just reply if you want to know anything else about it.

Failure of either of these gaskets or seals can be caused by a vehicle that sits for a long time. Hi Dave, the B4 Servo engages the 3rd gear shift, so if you are having issues with 1st gear as well… the poorly designed original servo cover may be contributing to the bad shift, but it might not be the entire reason. This sensor calculates vehicle road speed. I was informed that the transmission had been fully replaced; 2. I would recommend doing a few drain and fills with new transmission fluid, which is slightly more complicated than older cars due to the design. Because this is such a new vehicle, this sounds to me more like a software problem.
