Tech determined that 2 cylinder is misfiring. The only other problem I have besides that is a leaky vacuum air pump. Examine teeth on gears and their insertion holes into drums and such. My father is a Volvo Master Tech so we took it to the shop to reset the adaptives and installed the latest software. Will provide final update to see if this rectifies. Adam I think the acceleration issue and the downshifting issue are two separate things. If I do, then a rough shift happens.
Jack of all trades, master of none type deal. Also, has a very slight shudder when first accelerating. Complete with stopper cap and hang tab. The local Volvo dealership said I needed a new valve body. Just remember to accompany with a trans flush, and an ecu adaption afterwards. I did buy it used. I will definitely take it apart and take lots of pictures though.
A friend of mine just bouught a 2006 V70 with 160,000 miles. The pump is not located with pins but case halves are. I am considering helping her with a flush and drain and possibly the B4 kit. Each depression accurately dispenses 1 oz. For superior mobility it utilizes a manual pump, so compressed air or electricity is not required.
I guess because there are no codes, this may be a transmission issue but where to begin? The hydraulic valve solenoids that engage and disengage the gears have seals that leak over time, so it takes longer for them to fully engage. We replaced the valve body in our Saab 9-5 event support vehicle at around 170k same Aisin transmission. The delay is enough for a half engaged gear to bang into place. When I bought it, it was so smooth — no problems — and I loved it. It did seem to take care of it in about 3K.
The bad news is that each bang that is hard enough to perceive through the heavy sound and vibration dampened steel that your V70 is constructed of, is hard enough to potentially damage the transmission. That means there are tons of cars out there with ailing gearboxes in need of attention. I am thinking about changing trans oil again it was done 15,000 miles ago. Give that a shot, the fluid for your car is Part 93165147. Looks more like thin motor oil… Thank you, Steven Thanks for the kind words.
Is the wrong fluid in there? After that I kept getting a check engine light. But if I can go through and freshen the trans for a few hundred bucks, I'd rather do it now than after I've had a major failure. I recently bought an 06 S60R with only 64,000 miles. I am interested in hearing the results from the B4 kit. It engages with big bang. There is a great deal of attention and time that goes into each and every rebuild and there are also a few common failure areas, especially in the 99-02 models, and these are addressed and upgraded during the rebuild.
You should be able to find local mechanics and read reviews just by googling Volvo mechanics in your area. There should be a transmission section. When a valve body has a bad valve or a sticky solenoid, it will fail to adequately divert hydraulic pressure to fully engage the gear. The bang on hard ish stop ,feeling the car down shift has been going on since 90k. Honestly, while 65k is a great time to do a transmission service, it is very strange for it to be acting up so early in its life.
I can do most of the work myself. Flush the fluid with a and have the transmission control unit reset. Look for stress cracks, friction damage to pressure plates a small amount is normal , if it looks like a grinder was taken to it due to metal to metal contact from a worn clutch disk, replace it. However, none of these are considered end-all solutions, and eventually Volvo came up with a mechanical update to these transmissions. Because of the cost associated with a new valve body, if I were you I would give the B4 servo update a try because your car is relatively low mileage. And a few times it would not shift up if I have been driving for a while until I turn it off then turn it back on.
Only issue I have is shifting in D ir R first thing in the morning. I have a 2006 Volvo S60 with 114,000 miles which has given me virtually no transmission problems until now. Later cars that are experiencing shifting problems could benefit from simply flushing the fluid, or getting a software update. Read on if you choose, GotTransmissions. Generally, cars exhibiting valve body and fluid related issues are well past the 10 year 100k mile mark. The lever should move freely going into the transmission.
