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.

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."

Is the inside supposed to be this dry? I'm about to add half a quart to it. Yesterday I launched the car off a red light and the car completely slipped when it was trying to go from second to Third. I think I might be lower than I may think on fluid. Maybe the technician didn't put enough fluid.

Update, no issues so far after adding half a quart. Already put 150 miles on the car since adding fluid, id say its all good now, thank u/dougy!

I need to do this. I've got this problem as well as the Valve Body issue.
So the MAXLIFE ATF is ok to use in our R's?

excellent ...

Dougy quote of the day.

"first time it did it to me i knew that the engineer at Asin that could not figure out proper oil level is an imbecile"
The quote is for 06 and 07 6 speed auto trans that come without a dipstick.

Exactly what I always say when it comes to the "no dip stick decision" -_-

Is he any worse than the engineer at volvo that did the stress analysis for the 2.5's thin walled cylinders? lol :p

Definitely not. They never considered people modding these cars sadly.

[Volvo] never considered people modding these cars sadly.
This was a great thread. Getting a little off-topic here?

Sadly, the people modding these caRs never considered that Volvo (for whom I'm hardly a shill) had already modded these engines (and AWD) to darn near their safe limits when they were modded (hot-rodded) by the factory (incl special head gasket to deal with the increased pressures/temps, special water pump for running at higher RPMs, etc), such that they could last 'forever' if driven carefully (ie, keeping engine loads light and rpms below 3500 until fully up to temp, taking a cool-down lap before shutting down too hot, no neutral slams or clutch dumps, good synthetic oil, etc) by driveRs who appreciated what they had.

The engineers clearly thought about (and undoubtedly fought with beancounters) in order to make a reliable 120 hp/L, almost unheard of (especially in its day) for a de-smogged (ie, socially responsible) non-self-balancing (odd cylinder count) engine.

The Volvo engine engineers are certainly no worse than plain folks (owneRs) who just assume that whatever turbocharged engine output level that any factory churns out can always easily and safely be increased by simply turning up the intake (and cylinder) pressure (and temps)! (...then there are the really cRazy ones who go totally apesh!t and casually blithely replace rotating and rubber mounting components that were specially designed, at extra expense, just to enhance civility/refinement and longevity, to deal with 5-cylinder vibration issues ... so they over-stress the parts beyond their design ratings and then blame Volvo after the useR has broken theiR own caR.)

If someone bought a McLaren, should they assume that the factory engineers were 'fraidy wimps and that they are smarter than the factory engineers, and know more about making a car go faster AND making it last a long time? (heck, just exceed redline enough times...!) All systems have limits.

IMHO, Volvo engine (though definitely not any suspension!) engineers were good and brave to successfully push the limits of the(ir) design. It's easy for people (many of whom believe that if some is good, and more is better, that too much is just right) to exceed those limits, and then even easier for those same clowns to (mass-)blame Volvo engineers instead of themselves for having over-stressed their own caRs...

Sorry, but your point isn't clear to me.... Are you assuming that caR owners are naive enough to believe that our modifications don't compromise reliability? I suspect we're all well aware and the push for greater enjoyment is worth to compromise.

I agree with both of you, but what I'm saying is, they could've made the original 2.3 block a little more dense and had bigger cyl walls to help the 2.5 block. Isn't the newer 2.3 block different than the older 90s 2.3?

:hijack: Let's bring it back around, friends.



But seriously, let's try and keep it on track please.

Ok... Back to the VB

I just found out my trans oil pan has a leak. So when you get VB replaced, be aware how critical it is to keep the sealing surfaces clean on re-assembly. It's very easy to get a small amount of oil on the surface. A shop recommended letting it drain overnight so it stays clean (no drips) when installing the pan.

$500 to get this fixed.
