Andy, You were very helpful last week on my transmission question - 2001 V70 T5. I got it back from the transmission shop that I had taken it to (close to the shop that changed my fluids and wrecked 3rd gear) before I had connected with you. They rebuilt the transmission and they ordered a new valve body. In my exchange with you last week you indicated " a shop not familiar with Volvos wouldn't be able to reset the transmission fluid counters in the Transmission Control Module". Should I now take my car to my Volvo dealer to do a diagnostic"

Hello again, Yes, you will need either a dealership or a shop with Volvos VIDA software to reset the fluid counters and adaption values in the TCM. They will most likely charge name hour labor for this, so be prepared. Let me know if you have any other questions.

After two weeks of work I picked up the car a week ago and it was working well (only noticed thing was squeeky steering wheel). After 1 week of good driving I felt a slip accelerating and the "transmission service required" warning light come back on. It still drove fine but I went straight back to the transmission shop that repalced the valve body and rebuilt the transmission - i have not heard an update yet on the diagnostic. This is becoming a challenging and troubling effort.
This was after the dealer had it?
I hadn't taken it to the dealer as the shop indicated that they had already reset the fluid counters and adaption values in the TCM
Well if they rebuilt it, chances are something they did is what caused this current problem. Let me know what codes they get
I talked with them and they indicated that it is reading PCM Failure and needs a new module - and they are going to look for a guarenteed used one online. As I look online and read all the history on this 01 I start to worry that this may never get fixed.
I would strongly recommend a dealership diagnosis. There is no module called the PCM and furthermore, used modules won't work since they are programmed to the car. A transmission shop with a general scanner is not exactly qualified to diagnose that. Volvo has a new service program called Volvo Service for Life which gives customers up to one hour of diagnosis for free for any warning light, so if you have a dealership nearby, it wouldn't even cost to have it diagnosed.
,Andy,My 2001 V70 transmission challenges continue. I took it in to the Volvo dealer because of slipping between 3-4 and they reset adaptation and fluid change counter. Much improved but was still slipping/surging between 3-4th (they indicated possible damage or TCM issues)so I went back to the transmission shop that did the work and they rebuilt it. I picked it up on Thursday and the engine light flahed and stayed on shortly after driving away - it is steady light except it often flashes around 70mph on the highway for a while and occassionaly when starting out first thing while accelerating leaving the house in the morning. The transmission feels good now (no slipping 3-4) but is this a sign of issues still with the transmission? Suggestions? Thanks a lot,Mike
So now it's just the check engine light, correct?
Yes - that is it now. It is orange and stays on - it flashes around 70mph on the highway for a while and occassionaly when starting out first thing while accelerating leaving the house in the morning.
And flashing check engine light indicates a misfire damaging to the catalytic converter. This isn't directly related to the transmission, but they could have left something loose to cause a misfire. It could also be totally unrelated. Ignition coils are common on that model, it's possible one is on its way out. Without the trouble codes, I couldn't say for sure what's going on or if it's related to the transmission rebuild.
