Transmission and sensor issues finally solved without paying big money!

Post by UweCR » Thu Mar 30, 2017 9:23 pm

Hello Volvo Lovers

First of all, sorry for my english, its not my native language, but i thought it is a good idea to share my experiences as it might help some other Volvo owner who faces similar troubles

3 months ago i bought a 2008 XC70, who had some issues with the ABS, MAP Sensor and very weird shifting as soon the transmission reached a certain temperature.
Living in Costa Rica, with only one Volvo dealer, I thought that it would be a good idea to bring my car in to get a quote on the repairs. Well, long story short. He told me that the full repair would cost approx US$5,800, including a complete transmission overhaul, changing 3 sensors (front speed sensor left and right, MAP Sensor, inclusive software update.
Honestly i was shocked, as it didn't make sense to put so much money into the car. So I started investigating the issues, bought a "cloned" Dice, got Vida 2014 and did a intensive research on the errors
With the help of a local mechanic, Jorge from Grupo Autobahn, I was able to point the culprit parts. So i ordered 2 speed sensor and a MAP Sensor at Amazon, which cost me including shipping, customs and installation (Jorge did that) around $200
But the most critical issue was the transmission problems, one day, driving on the highway, the car shifted really heavily up and down and then "hung" at the second gear. Only turning the engine off for a few minutes resolved that issue, but switching gears got worse by the day.
So i asked around a found a "Specialist" for automatic transmissions who told me that some valves inside the transmission needed to be replaced, whcih would run around $1,600. Somehow i didn't trust that guy too much so we started looking deeper into this issue.
After a few days i realized that the car was shifting just fine until it reached a certain temperature, and i found a post here at the forum about a guy who had similar issues, resolving it by adding an additional oil cooler to his car.
So i thought, why not, somehow it makes sesnse, as oil can loose viscosity when it gets too hot and living in the tropics, warm weather is a daily thing here.

Long story short, i bought a oil cooler, incl installation kit on Amazon - around $50 - including shipping, customs and installation i paid another $200.

Obviously we had to flush the oil (Note that the volvo dealer here said that this should not be done and would destroy the transmission!!!!) and replace it with fresh Oil. I actually bought the Toyota brand, apparently its the same, but MUCH cheaper.

In total i spent less then $500 for all the repairs and finally are able to enjoy my car. No more check engine or other warning lights, shifting without any problems. All 100% perfect.

Bottomline. If i hadn't found this forum and got so many helpful advise here, I probably would have spent a couple of grands into all those issues, as i'm really not a car specialist.

So i would like to say THANK YOU to all the people at the forum who spend their time helping people like myself to get their Volvo's up and running and truly hope that my little story will help somebody who faces similar issues

Pura Vida

I'm wondering about flushing the trans. I'm buying an XC70 2008 with about 100k miles and noticed the trans had recently had a flush by a muffler shop. The selling dealer (not volvo) had it done. So I'm wondering if it had a shift problem or if this is common. I'm buying it remotely but will have Volvo dealer inspect before purchase. Regarding trans fluid, the latest fluid is low viscosity. And there is synthetic. The newer trans require the low viscosity but I think this is to reduce friction to meet mileage reqts so a higher viscosity fluid would probably work better. And this would explain the high temp shift problems. Anyone played around with different fluids? Or synthetic? Is it OK to flush it? Is there a drain plug? Dipstick?

It’s ok to flush it. Note that Volvo switched from JWS3309/Toyota type T-IV to Toyota AWS for the Aisin 80FC transmission sometime in 2011 so best to check with dealership to confirm which your car needs.

I took my 2012 Volvo XC70 T6 to an alleged Volvo specialist last summer. They tried to flush the transmission - but reported that they could not. The shop manager said they did not have the proper type of flushing machine. Then he said they put it in gear, while car was on the rack. He said the car would not push the fluid through, and they could not exchange all fluids. I thought, Volvo built some feature into the car that requires an owner to take it to a Volvo dealer ship.

I ended up draining 3 quarts from the drain plug on 3 different occasions over the next year. I replaced the fluid each time with Mobil 1 Full Synthetic. Now I have harsh shifting sometimes. The vehicle has only 58k miles.

The drain plugs and fill system is definitely odd. I assume Volvo does this to discourage DIY mechanics.

I'm not aware of your particular transmission, but you may want to search what is the exact fluid that it takes. Once with the correct fluid, if it still has problems, you may want to do a transmission reset see how it goes.

Here's just a post for P3 cars if you have the same transmission http://volvospeed.com/vs_forum/topic/17 ... uid-flush/

On the 2012 T6 you remove the Torx 40 center plug in drain plug and then remove the drainplug/level setting plug using a 17mm hex wrench. The fill plug is near the left front top corner of transmission and is visible next to the gear lever on transmssion. That plug is Torx 55. Install the drain and level setting plug but leave the torx 40 center plug out. Add 2 quarts of appropriate fluid and then start and add just under 2 more quarts. Run the engine with vehicle level for 10-12 minutes allowing the fluid to drip or run from plug. AT that time you should have fluid temp in more or less correct range and you install and tighten the Torx 40 center plug.
I'm not aware of Mobil 1 synthetic being available in the correct spec. The corrects spec for that year model is known by a few names like Aisin WS, Volvo JWS3324, and others. That trans still has cooler lines but these use a newer stye fitting and there is a thermostat that blocks fluid flow to cooler circuit until fluid gets to 125F or a bit higher. A lot of transmissions have these thermostats now. In really cold temps the fluid needs to get up to a warm temp for good transmission function and better MPG.
