      R&R V8 Transmission? Step by Step?

      Hi guys. I'm usually hanging out at tbricks.

      So I just bought a 2006 XC90 with the V8. It has 104k miles on it and is in great condition inside and out. I bought it knowing it had tranny problems, and it turns out the front pump is bad. It whizzes in neutral and won't go forward or back. No pressure.

      So I've googled a bunch but I haven't found any helpful posts or walkthroughs of removing the TF80 from a V8 XC90. Does anybody have any helpful links? Are there even any photos of somebody pulling a TF80?

      Appreciate any help!


      Oh, and btw I got it so cheap that even with a transmission rebuild it will be a good deal still! I paid 2300.

      Removing the transmission is about the same work as removing the transfer case ...

      Support engine, disconnect exhaust, lower control arms, remove right driveshaft, steering rack, disconnect prop shaft and drop sub frame (biggie) ... not for the timid. Approximately 9 hrs to get to the transmission.

      You could also get a "subscription" to VIDA and print out the repair instructions. VIDA will usually come with DiCE units you can get on ebay, amazon, aliexpress.
      I've seen guys do as PAX5 and I've also seen some drop the whole engine with trans on the subframe and then proceed to "pluck" the transmission off the side.

      Dropping the entire engine requires that you also disconnect all of the fluid/fuel lines and wiring harness ... lots of work.

      But the advantage is that you can do all kinds of preventive maintenance, like spark plugs, serpentine belt and bearings, etc etc

      Hmmm. On one hand this truck is brand new to me. I need to stage zero the thing and this sounds appealing. On the other hand, I'll be doing all this in my driveway. Dropping the whole engine and subframe would be quite the balancing act.

      I have done transmissions and motor swaps before, but the AWD and sideways V8 changes things a little! lol

      If you have the time, the tools and the patience. you can do it. Volvo uses high quality fasteners, you'll enjoy taking them apart, but be prepared for some odd sizes, like 15mm and 18mm ... Exhaust studs and nuts will be frozen/rusted. You want to be careful removing them because the double cat is expensive. Replace all nuts and bolts that have torque settings with Volvo OE. There is no substitute and it is cheap insurance. You only want to do this once!

      Search/contact for "oneofakind" on this forum. He did it in his garage (starting at post #278 - http://forums.swedespeed.com/showthr...90-today/page8). His hoist is "available" ...

      Here's a quote from him:

You could raise the engine, but you'd have to remove any lines that aren't rubber. My opinion is that dropping the subframe will be easiest. If you have a lift and lifting table available, it would take much less time than what mine took. I was dealing with about 4 inches of clearance above my face, so dealing with 2 jacks, 6 stands, and 3 dozen tools ate up time like no other. Just make sure that you let the chemical gasket set up for 24 hours before you add fluid. You don't need it to push out and have to take the subframe off again.

      I only replaced the valve body though, I didn't pull the whole transmission. It may be a good starting place, but your symptoms sound way different from a failed VB. If you're going to be doing something this in depth, I would highly recommend you invest in a VIDA unit. I was going to make a write up for replacing the VB, but decided against it because you could get into some serious trouble if you missed a step or didn't understand a step perfectly. I'll snap pictures for people all day long over hearing that my instructions caused a fuel line to shear or worse. I also decided to keep the engine support I made because it'll come in handy in the future. But what you see in that picture is all it needs. A couple 4x4 and 2x4 cut to the right length, 2 eye-bolts, 2 rings, large washers sunk a little ways into the wood, and nuts to secure it. Took me 10 minutes to make and held firm for the week+ the engine was only supported by that. Feel free to send me a PM for more information and pictures!

      Awesome, thanks.

      I am working on the Vida now. I have 2 laptops I could use, but neither has enough HD space and I can't wipe either one of then clean.

      I might buy a cheap one from craigslist and dedicate it to Vida. There's actually a toughbook for sale right now in my town.

      The above engine support is simple enough to make. Although I still haven't decided whether I'll keep the motor in place or drop the whole thing.

      Dropping the whole engine, trans, steering rack on the subframe you really would need a lift to get enough clearance as the car would need to be raised a few feet. It really doesn't take long to do it that way. I've seen them dropped in less than two hours but then there is still a lot to take apart even after its out. Exhaust manifolds still have to come off iirc to access two bell housing bolts. Would also be a great time to replace the alternator though
      Either way you will be busy.

      Is the TF80 from the 3.2's the same thing?

      I may try to buy one from a junkyard to swap. If it's the same that opens up my choices!

      From what I remember when I did mine in my "driveway":

      - Hold the engine from above (as per one of the previously posted pictures)
      - Remove radiator (otherwise it's very very hard to remove the exhaust header, possible but difficult)
      - unfasten the exhaust headers bolts (both sides)
      - remove exhaust flex under the subframe
      - you need also to unbolt the flexplate / torque converter assembly by rotating the flexplate with a flat blade screwdriver and undoing the bolts.
      - drain transmission
      - remove subframe
      - remove angle gear (and passenger side axle)
      - remove bolts securing transmission to engine - better use something to support the tranny as it's heeeavy!

      since you're there... change the rear crank seal.

      Let us know if you are able to make the swap.
