I been having some issues with the tf80 in my xc70, did some fill and drains and it got a lot better, but then i had some flares again specially 4-5th. it seems to happen when the tranny gets real hot, like 95c and around there. Im sure i should get a new VB but before i throw all that money in, im wondering if i should try adjust the c3 solenoid from sonax's writeup. cept for the flares my transmission behaves very good compared to the issues i been reading people having.

Not really anything to lose to try right?

Can i adjust it with the valvebody still in the transmission or do i have to take out the vb to adjust it?
Do i have to drop the crossmember down to get the cover off to get acess?

Looks like I'm right on the edge. Phew.

 

Hi,

Long time lurker but first time poster.

I was interested in finding out if anyone has experienced the valve body wear issue in a 2007 XC90 diesel with the 06K TF80SC transmission?

I note the cut-off seems to be 06J, but some V8s with the 06K transmission appear to be impacted?

My car is throwing an TCM0051 error: "Lock-up solenoid SLU stuck in position OFF". The issue seems to be triggered under load when warm e.g. driving up a hill. The transmission is occasionally flaring and hard shifting also. "Transmission Service Required" is displayed. Tried several drain and fills to no avail - behaviour/error code keeps appearing.

I'm about to purchase a new valve body but want to be fairly certain it will solve the issue given the expense! My only uncertainty is that my transmission is an 06K.

Any guidance appreciated.

PS. Pulled out my old valve body - it's marked 06X on the serial number. Not sure if it should correspond to the 06K?

Thanks
Ramilio

Looking for help figuring out TF-80SC TCM software versions! Does anyone know what the latest software number for the TCM is? You can find your software number(s) using VIDA (Diagnostics>Network>TCM). If anyone knows they had a software update (or haven't) and have the time to check their number I would greatly appreciate it. I have attached mine in the screenshot, I have two, does this mean I have at least 1 update (no idea).

I am having the common 3-2 clunk and rare 1-2/2-3 slam shift at low throttle. Trying to get into Rolling Motors to have the VB checked/replaced but he is booked up right now. Recommended I update the software myself, but it seems you can't check to see if the latest version is installed without paying for it first. So trying to avoid paying $1-200 for nothing. Many poeple in this thread have said "check to see if you have the latest software" is there an easy way to do this that I am missing?

VIDA will tell you if an update is available

 

I am running 2014D offline. I believe you need a paid subscription and the official version for VIDA to do anything update related. However I'm under the impression that with the subscription I would still have to pay for the software itself to check if I'm up to date. Are you saying that with only a subscription VIDA will check for the update for free?

Yes thats what I'm saying.

 

Yes thats what I'm saying.

Thanks, I will try that eventually if no one can provide an updated software number. Wasting $80 would still suck.

Well, even if there isn't an update, there will probably be updates for other modules, you can buy a total can and get the car up to date in every way possible

Update: The software number 0030759621 is what I assume to be updated one, and the former the original. No TCM updates with VIDA, just DDM and PDM which I passed on.

 

Hi,
I think that lots of problems are from too high oil temperature. at the same time, body valve wears and then dysfunctions.... So check continiously the oil temp with car scanner and bluetooth obd, and read this very interesting post: Alfa 159 Gearbox Cooler Modification - Jabawok Industries

 

curious to see what the thoughts are on my 2016 s60 3.0 with tf-80sc. getting flare after shifts when warm and occasional clunk into 1st gear. did a drain and fill but im going to do another one as I only did 6L drain and fill.

 

Question as to compatibility of swapping a 2007 TF80SC (from an S60R) into a 2006 V70R - any issues I should be aware of or is it simply plug & play? Thx in advance.

 

Should be plug and play

 

I have a chance to grab a Valve assembly from a 2010 XC60 with the TF-80 FWD Trans... Would anyone be able to confirm if this is a compatible Valve body unit?

I'm seeing conflicting reports, some saying that ALL the TF-80 Valve bodies are the same.

@10:35 says that there is 2 different types.

Any ideas as to when the different types might switch over?

Any insight is greatly appreciated

Donor trans tag info;

30783420
T09C3811545
Serial # 09C3811545

 

Ok, Since no one else replied, I'll update my findings, and hope it helps someone else.
No, they are not compatible, there are indeed 2 different units I'm aware of. The later model has a lip surrounding the side of the solenoids, and has a 12 bolt pan with some ridges on in.

The one's from the R's and earlier models of TF-80's has no lip around the solenoids, as well as having a flat faced 11 bolt pan.

 

Also found a useable unit from an;

07 XC90
VIN: YV4CZ982571406824
MFG: 04/07
Trans Serial: 07A3825527

 

^^^^thanks for posting this information - greatly appreciated. I have both a replacement auto and a full manual swap kit and am still on the fence as to which direction to go. Time (which I have very little of) may dictate my direction. Are you planning on swapping just the VB or the whole transmission? Pulling the engine to swap or working around it? Thx.

 

I’m swapping the VB to an updated unit, along with the TransGo kit. It was relatively painless to do, just had to be strategic about how to separate the sections. Removing/sliding the upper halves with the plates, flipping over, sliding the plate off then moving to the lower section and repeat. I found sliding the plates off the sections best to keep from pulling up pieces and have them drop out. Kits done, just awaiting new gasket set from Cobra.

I plan to RnR In-car, i can only comment taking the unit out of an xc90 as I haven’t actually done my VR yet.
I had to drop the subframe, and pull up on the engine (the supports were removed prior to by someone else) and clear the way in front of the pan. The trans oil lines were in the way, as well as a brace. Swivels and various extensions & wobbles helped a lot.

My issues aren’t bad, just under heavy foot its a bit hard when it shifts. So if I’m just cruising it doesn’t show much, but on downshift. I imagine a refreshed/healthy VB and a fluid flush should probably take care of my issues.

 

Hello. I have a problem with shudder / vibration when accelerating. My Car is Volvo XC90 3.2 with Aisin TF-80SC production date 48 week 2007. The problem occurs in 2-3-4 gear. The car was taken to a specialist who concluded after a test drive that it was the fault of the torque converter lockup. The torque converter was regenerated and the symptom remained the same or even stronger. Please give me some suggestions. Could this be VB fault?

 

Adding data to strange VB issues - I have XC70 2007 (from April 2007), TF-80C is 06M and have had the VB and turbine change previously on 2017. Now, TF failed again, where the oil is not red/brown or even black, but silver, full of metal particles..
Plan to swap to newer than 06M. Anything I should be aware of? Is there any model that I cannot swap to (perhaps some changes made in 2010-2011)?

 

Hello, could you tell me which solenoid f is on a TF 80 SC gearbox in a 2012 Volvo S60? Thanks.
