I wanted to make a post where I could assemble the assorted things I've found regarding the Aisin TF-80SC Transmission and its valve body problems from MY 2006 to MY 2007. I developed it over in the XC90 forum and it's now ready for "prime time" here in the R forum where it will get more exposure.

Models affected:

2006-2007 Volvo S60R GT
2006-2007 Volvo V70R GT
2006-2007 Volvo XC90 V8 (All Trims)
2007 Volvo XC90 3.2L (All Trims)
2007 Volvo S80 V8 (All Trims)
2007 Volvo S80 3.2L (All Trims)

Transmission Wiki - "It is designed to handle a maximum of 440 N·m (324.5 ft·lbf) of torque."

The Technical Deficiency:

From this post some details about the problem:
What goes bad in the valve bodies is the bores in which the valves ride. They become worn out and cross leaks occur that no amount of reprogramming can compensate for. The TCM turns solenoids on and off to stroke valves to direct fluid to specific locations inside the transmission. When the valve bores are worn out that control of flow is no longer possible.

This thread, from user MnOpRacInG, shows a tear down of a failing valve body. The worn bores and valves are clearly visible, as demonstrated in the photos below:

Here's the TNN regarding the valve body:

(Dated: 11-09-2007)
TNN43-53-2007-11-09 Title: Valve Body: Customer Interest - A/T - Harsh Shifts/False Neutrals/Shift Flare
MODEL/YEAR:
2005- for XC90 V8
2006- for S60R/V70R
2007- for XC90 3.2 & S80

SUBJECT: TF80-SC, 6 Speed Automatic Transmission Fault Tracing Tips
REFERENCE: VIDA, TNN 40-02
Note: This TNN supersedes the previous 43-53, dated 12/21/2006. Information about speed sensor and valve body faults has been added. Please update your files.
This document summarizes customer complaints related to the 6 speed Automatic Transmission (TF80-SC) and should be used together with the information in VIDA.

Valve Body: The Valve Body should be replaced to address the following symptoms:
1. Customer complaints about 2-3 upshift quality. The shift may be described as harsh, or as a shudder. The symptom is usually more apparent during the first few minutes of driving after a cold start.
2. Customer complaints of shudder when slowing down, just before coming to a stop. The symptom may also be described as a harsh downshift just before coming to a stop.
3. Neutral condition in 4th, 5th & 6th gear; normal behavior in 1st, 2nd, 3rd & Reverse. One or more of the following DTCs (Diagnostic Trouble Codes) may be present in the TCM (Transmission Control Module): P073400, P073500, P072900, P089600.
4. Neutral condition in all gears except 5th & Reverse, usually with TCM P273300 set. DTCs for gear ratio(s) may also be set such as TCM P073000, P073100, P073200, or P073400.
5. Customer complaints of engine RPM flare at upshift or power-on downshift (kickdown) due to a worn modulator valve bore.

Note: Transmissions starting with serial number 06J and later already have the latest valve body which is designed to prevent these symptoms.

Replacement Steps (S60R/V70R):
Thanks Laird for the Walkthrough

"I removed the bumper cover, since that takes 5 minutes, this allows excellent access from below.
Remove air guide, both if you have them.
Remove the tranny coolant lines.
Remove the air-box, fake battery cover and IC to TB tube.
Remove front motor mount bolt (on top of mount)
Remove the pump on the frame rail by removing two bots and the whole bracket.
Put jack-stands under the rear sub-frame brackets and loosened the rear SF bolts.
Floor jack with a block of wood under the engine, bit of tension.
Removed front SF bolts to allow SF to sag out of the way.
Drain fluid (save or measure)
Remove VB cover (clean clean clean)
Take a few pictures, even though it'd be hard to screw up the wiring.
Don't lose the metal lock plate that goes with the top left sensor.
8 bolts (10nm) and you will get a fair amount of fluid when you remove the bottom two bolts and internal cover plate.
Clean tranny surface.
Install (the new one) and ensure that everything is hooked up and tight. Don't forget to get the shift arm and link hooked up on top.
Permatex (gasp) grey RTV $5.99 or the , "pick a manufacturer" RTV re-labeled as VOLVO, $$$$, your choice. Follow the directions. (Editor Note: Personally recommend Volvo Sealant)
Put everything else back together except what's in your way of refilling and wait 24 hours.
Fill and drive.
Smile at yourself in the mirror and/or pat yourself on the back."

Thanks Thommykent for sharing this photo of the connections:

(I would like input on the differences in how the job is done between models.)

How to find the transmission serial #:

On the R's, the transmission serial number can be found by looking behind the airbox below the intake tube. There's a metal tag on top of the transmission which has the serial number. It looks like this:


There's a similar metal tag on top of the transmission of the V8's. Here's a photo which shows the location. It's taken while standing next to the driver's side wheel well of the XC90:
Image Link Broken

Also, from this post you can find the transmission serial number on V8's by:

"With a good flashlight on a cold engine compartment, stick your head over the near side of the brake fluid reservoir and look straight down.
White sticker with the SN. Just toward the front of the sticker (toward front of car) is the metal plate with the same SN."

Mine was starting at T07D, but recently I'd used VIDA to check four ABS sensors' reading, and found out the rear right sensor reading was insane which was 6 digit shown.(ex:248954 km/h). I do experienced rough down shift from 2nd to 1st recently, not quite sure if the ABS false reading affected it, but will replace it to see what happen.

I will have to say that if you have a GT car and run a K&N filter I would dump it. Best thing I have done to help drivability and improved shifting in everyday driving. I also recommend using Maxlife ATF as a good all around trans fluid during a pump and dump

So, what's the generally best solution to this problem? Take it to a dealership who can look up the specific issue and do the fix, or is it preferable to go to a place the specializes in transmission repairs?

Anyone around DC/MD/VA had this work done with success at a reasonable cost?

If your transmission serial # is 07D, then you don't have this specific issue. That doesn't mean you have no transmission issue, it just means you don't have THIS one. Sounds like you need to keep going down the road of clearing your codes. If you are worried about transmission condition, a fluid flush is always a good idea.

If anyone has an R, regardless of transmission, they should dump the K&N. It provides no benefits and only potential issues (oil on MAF, less capable filtering, etc), but that's all for another post.

If your 07 has a serial # below 06J, then you need a new/rebuilt valve body. My advice would be to buy from one of the sources in the post. Maybe someone else can help direct where to go to have it done. It should be billed at just over 4 hours labor, so keep that in mind when considering pricing.

Outside the U.S., Rs go by MY 2003-2006. The U.S. has a unique way of branding MYs that puts them a year ahead. Volvo probably released the U.S. 2007 MY (2006 outside the U.S.) in late 2006 (which most U.S. brands do to make customers feel like they're getting next year's model early). So Volvo had already been making the U.S. 07 Rs months prior to that. I believe the last Rs were actually made in March 2007, and they contained some components of the "2008" MY, like steel control arms and a 3.5 mm jack in the center console.

For reference our 2007 v70r 2/07 06L has the steel control arms and the 3.5 mm jack. The steel control arms are shaped to give a little more steering lock which is still terrible.

My 2007 S80 V8 has a "delivery date" of Sept 11, 2007 and TF80-SC S/N: 07A3828059
Given this, I really doubt any 2008 models would be in the problem range, as the problem range ended well before my 2007 model...

2007 V70R
Production date: 03/07
Transmission: 06M

Replaced the VB at 43,000 miles a few months ago when I bought it.
The sliding valve bodies had a burnt oil haze-look to them.

Too much heat, or maybe lack of fluid through the the valve bodies. Hopefully a bad design they corrected with the new ones.

Do you have the CarFax that you could pull the production date from?

Interesting. 06M is after the 06J cutoff, so yours should have come with the "fixed" valve body.

Mine suffered from the nuetral rev upshift and crashing drownshifts. It was replaced with new OEM by Nordic in PDX when I purchased it. It was so bad during the week I had it I was only driving in manual-mode. At the shop there was a pile of old VB's that had been replaced and there was an 06 XC and VR there getting VB replacements. The ones I inspected (including mine) had the oil-burnt haze on the sliding valves. Ole at Nordic mentioned he no longer uses rebuilts for quality/reliability issues. This may be a business decision which I understand.

My guess is the problem is bigger than what was identified in the bulletin.

Also...
Volvo production tag: located on drivers side, rear door jamb. The month/year are on the placard (no day). Much more accurate than a delivery date.

Thanks for collecting the information.

I made a mistake that I correct later in the thread. The production of my 07SR was 07/2006, which makes sense because the delivery date was 01/2007. (I would think it takes an average of at least 6 months for U.S. delivery.)

I confused the date with March 2007, the latest production date of any R I know of.

This is very insightful information wrt the VB issue.

So for an 07 with 104k that I'm pretty sure just received its first transmission flush (filthy, but no noticeable metal bits or obvious signs of gear wear, according to my mech), did you notice any damage to the transmission, or would one be good just having the new VB installed?

After the VB replacement everything was fixed.
At 43k miles it was surpising the VB showed any symptoms. It recieved a drain and fill days before I drove it (before any VB symptoms) which obviously didn't help.

Personally if you are not experiencing any issues, I'd keep driving it, and change fluid every-other oil change for awhile.

Your first step should be to go peek at your serial #. It's REALLY easy on the R. At least then you'll know whether you are in the officially affected group.

Have you tried driving your 07 in GT mode? I've found I can avoid many of the issues by doing this. Might be worth a shot.

Yes, I know I'm in the affected group. My serial is posted above. I looked up the issue right after I bought my 07 last October because I noticed the f'd up shifting. It's interesting the issue is coming up again in this forum. Shouldn't this be something any Volvo dealership would know about and be prepared to fix? Argh.

I have driven in GT mode-sometimes switching to GT just because I can feel it idling in 4th when it should have shifted to 5th ten seconds prior-and will from now on mostly until I get the VB fixed.
