Transmission temp hot message 2007 C70

Post by June » Mon Jul 15, 2019 12:51 pm

I had to pick my daughter's 2007 C70 up from south Florida and am stuck in central Florida in route home to Jacksonville. I see Volvo has not fixed the overheating issues with the Japanese transmission. My 1998 had same issue but had a dipstick to add fluid after a overheating. This one spit the fluid out the vent just like the 98 did, but I cannot find a dipstick and I don't think it takes Dextron like the 1998 did. I hate to call a wrecker and have to be banged around for 100 miles... any advice quickly of what to add and where would be appropriated. I am sitting at a truck stop now. June

I gave up on checking or adding fluid. I moved from the interstate where I'm going to want to run 90 like everyone else to a rural highway and it is still going. 55 with the cruise. The designer who keeps using these crap Asian transmissions should be SHOT!!! From 1998 to 2007 is a lot of years to fix the cooling system to allow these cars to exceed 80 without transmission fluid overheating. The S80 4T65 cooling system doesn't do this and has a dipstick tube right to easy reach... I wish this car had a manual transmission. Thanks all. Hope I make it home! June

Hope you made it home with no further issues with the transmission. How much did it spit out (the mess in the engine compartment? Sounds like it could be a fire hazard or at least toxic fumes going into the cabin. I bypass my 03 Odyssey's radiator with a large transmission cooler quite a few months ago.

I have not seen temperatures over 165 since the installation. Radiator is around 180. This is siting idle for a lengthy period after a long drive. It is a big cooler however and has slightly affected the AC condenser to dissipate heat. The cooler sits in front of the condenser and radiator so that area is no longer getting cooler ambient temperature.

There is a Transgo kit also. I installed a Transgo but different kit for my 2003 S80 T6. Very nice so far. Between the cooler and shift kit I think the transmission should last awhile unless it's been damaged already.

Thank you! I made it home. I am unsure if I damaged the transmission. I am quite disappointed with Volvo. You are right I will have to have the Hayden cooler added. That makes sense to me. What transmission does the 2007 C70 T5 have? I assume it takes the Type IV fluid? Does it have a dipstick? The owners manual is strangely silent about the transmission. Sitting today at that gas station I did consult the manual before asking for help.

Don't worry about your 2003 T6 transmission as both I have had have been rock solid! I am not impressed with the Asian transmission's inability to sustain greater than 80 MPH without spitting the fluid out the vent on top and shift flairs. I blamed the 1998 V70 issue to the AWD system causing stress heat. June

1) The Aisin AW AF33 is a 5-speed automatic transaxle developed and manufactured in Anjo, Japan by Aisin AW, a division of Aisin. It is designed to be used in transverse engine configurations in both FWD and AWD configurations.

The actual model codes are AW55-50SN (FWD) and AW55-51SN (AWD).
Fluid must meet the JWS 3309 specification . The fluid can be found under varying designations.
https://en.wikipedia.org/wiki/Aisin_AF33_transmission

-
2) IPD confirms the 2007 C70 T5 has the AW55-X SN

According to Transgo their shift kit fits the following: Wiki shows these also.
Fits Volvo 2001-2007 (AW55-50S/N ) Saab 2002-2007 (AW55-50S/N) Nissan 2004-2007 (RE5F22A) Saturn 2003-2004 (AF33-5)

3) This Youtube video shows the 2004 Maxima transmission being repaired. At 8:30 - 9:30 the pan and valve body looks like Volvo's (See link to Volvo's diagram below)


Volvo Transmission Diagram
https://www.volvopartswebstore.com/show ... Line=11324

4) JWS 3309 Get this while it's still cheap. It's made the 03 Odyssey reverse clunk/grind go away even after 235K on the OE transmission. Full flush on both the 03 Odyssey and 03 S80 T6 (w/ Transgo kit). Shifts are more positive on both.

Price: $52.53 & FREE Shipping
https://www.amazon.com/HAVOLINE-2265364 ... 184&sr=8-3

It looks like there is a good possibility that the transmission can be worked on by one of us (amateur DIY'er)?

Try a drain and fill first as my friend has a 2005 Maxima and everal years back did a drain and fill and it solved a rough shifting problem.

Lastly, the Volvo diagram does show a dipstick?

Thank you MoVolvos for the links. They have helped me. I see a dipstick and tube on that diagram. It must be in a tight spot on this car. My 98 had a stubby yellow dipstick that went straight into the case and was hard to get to, but useable.

I'll dig around more in the morning and find that dipstick! Ordering fluid is next. Thank you so much! June

You are welcome June and thanks for asking the questions. I learned just as much as you and I won't be afraid to buy a Volvo with the Aisin AW AF33 now seeing we can work on the valve body ourselves.

I am totally stumped! I cannot find the dipstick for this transmission. Interesting enough the car's window sticker lists the car as having a 6 speed automatic, but doesn't give the model number of the transmission. I found the sticker in with the manual.

I have noticed other problems like the lower door speakers and the speakers in the backseat don't work. Just the highs and subwoofer come on and I broke the door pull on the door panel closing the door. Also an exhaust leak is apparent and now the check engine light is on... This car is not built to the standard I am used to from Volvo. I am so glad I have heald on to my 04 S80! June

Oh No, I was leaning towards selling the 03 S80 T6 for one of these:

Last month the owner was willing to drive down for me to see it but... The ad was removed but then returned.
https://greensboro.craigslist.org/cto/d ... 93013.html

Was looking at XC90 exclusively but couldn't pass up the low mileage 03 S80 T6.
https://raleigh.craigslist.org/ctd/d/fu ... 78496.html

Pertaining to the transmission can you plug the VIN into eEuroparts website and see what transmission parts they are selling for it? I think IPD could also help figure it out if you call them.

BTW I have custody of the C70 for the next year as she cannot have a car on campus for her first year at her new university. Stupid rule if you ask me.

Anyway more idiocy and cheapness on Volvo's part. I thought I would check the fuses for the radio and several are listed but are not present in the listed fuse panel???? Also the under dash cover is a cheap piece of insulation on the 07 C70 yet nice plastic matching the dash on the 04 S80.

Note the fuse panel picture in the owners manual even shows the fuse numbers starting in the 30s in the panel but fuse numbers begin with 1... No mention of where #13 a 15A radio fuse is located. #13 in the engine bay fuse panel is a relay so not there and no other fuse panel is listed in the manual.

Nonexistent fuses, not findable transmission dipstick, cheap insulation where a solid plastic panel should be, a goofy spider radiator hose which took out the head gasket, and God knows what else is cheapened vs the P2 S80 and Volvo cars before. I will have to look more closely at the next service loaner to see if Geely has brought the quality back.

Keep your S80, the 2000 S70 is fine but the P80 is clunky compared to a P2 car and the 3.2 is underpowered in the XC90. June
