Transmission solenoids

[asummers]

Does anyone know if the transmission solenoids are accessible, and maybe a do-it-yourself kind of job to replace?

My transmission warning came on two months ago, and my small shop Volvo mechanic read the codes on the tranny and told me the solenoids need replacing. He quoted me around $500. He cleared the codes, but now it is back.

Hey there...others have dealt with this but don't recall the exact fix, if there was one and if the solenoids can be bought individually. Seems they were in a rebuild kit. Maybe this link will help you: https://www.matthewsvolvosite.com/forums ... 11&t=15678 Also, try contacting Les & Reiley who was posting the questions and coming to some conclusions about how to go about dealing with their solenoid issue(s) if this is truly your issue as well.

Here's a quote from this 4T65E transmission site: http://www.tripleedgeperformance.com/4T ... n_Info.php

Solenoid and or Valve Body replacement:
This is a very commonly asked question..... How hard is it or is it something I can do in my garage? The answer will vary depending on mechainical skills and your tool supply! Because this is a front wheel drive transmission and the arrangement of the internals you CANNOT simply drop the bottom pan and access any of the solenoids or the valve body. In order to gain access to the solenoids and / or the valve body you must lower the transmission out the bottom of the vehicle. Every different vehicle line is arranged different so I cannot provied information that is specific to all models. You will need to have some sort of engine support device as the engine must be held up because you will be dropping down or removing the support cradle under the front of the vehicle which contains engine and transmission mounts that support the drivetrain. On some vehicles you must remove the cradle complete out from the vehicle while some you can just remove a section of the support cradle. You also may be required to completely remove the transmission from the vehicle while most you should be able to use your engine support and lower it down enough to remove the side cover of the transmission. You have to remove the side cover of the transmission to gain access to the solenoids and valve body. Often times you can reuse the side covert gasket, but if it is damaged you will need to replace this item and it is a dealer only part that is pretty costly, so be careful with the original! Before you remove the side cover you will need to drain the transmission fluid. You will also need to remove the drivers side axle, unless you plan to just leave it hang from the axle but often there is not enough room to do this because of suspension components. Once the side cover is off you will have full access to inspect / replace the solenoids, pressure switch manifold, and pump/valve body assembly if needed. This is a very labor intensive job and a $50 solenoid can quickly turn into a $500-$1000 job depending on vehicle and shop labor rate, so even though it is hard to gulp a quote that you recieved from a shop it is certainly expected once you know why it is so much and the labor needed to do the repair. This is something that can be done with patience and the right tools and a good mechanical aptitude. Though an experienced trans shop or a tech can do this in roughly 4-8 hours I would plan a full day or two worth of down time. Even if everything comes apart smooth you can run into other problems along the way or find more problems than originally sought out. I hope this helps in the understanding of what is involved to make in car repairs, for specific vehicle information I would recommend contacting a local shop or finding a repair manual for your vehicle.

For a straightforward remove and install of this gearbox the Volvo time is 7.1 hours. More time will be needed to replace solenoids.

I have been posting on as many post as possible regarding transmission 4T65E GM. I have the "urgent transmission service required". (1999 Volvo S80 T6). First mistake was thinking the Volvo dealership would pull different codes than my obd2. Cost me a $104.00. They basically told me I need new transmission. The code was shift solenoid b. Please understand the shift solenoid is a electrical fault not a mechanical fault!! That means if your only getting an electrical fault you can change the solenoid and you should be fine. Find a reputable transmission shop to drop transmission in order to get to side panel. have them change both solenoid A and B. Make sure you also do the transmission service with a filter change. I paid $600 for the whole job. So far so good. Keep in mind I constantly changed my fluid every 20,000 miles since I bought the car at 65, 000 miles. I learned it had a dreaded Gm transmission. The transmission light came on at 187,000 miles. If your getting mechanical faults you need to have it rebuilt. Remember change your oil, transmission fluid, antifreeze and you'll get hundreds of thousands of miles out of your vehicle, at least European cars anyways!!!!

what about a "whining" noise each time the gears change? is that mechnical or when a solenoid goes bad? i got 1 code stating"3rd gear fault" or something like that.. cant remember exactly....
