Volvo Maintenance Hints for 7xx/9xx - Bill Garland's Nuclear ...

olt in the center of the flange. This bolt holds the flange to the output shaft. Once it's out you can pull the flange out of the housing.
Remove the 15mm nut in the middle of the transmission mount (rear end of transmission). Support the pan with a piece of wood held up by
a floor jack, just enough to take the pressure off the tranny mount. You should see the mount bolt come up slightly. Then remove the four
bolts that hold the mount to the chassis. The mount will come off, and the tail housing will be clearly visible. Four bolts (14mm I think) hold
the housing to the main body of the tranny. The top and bottom bolts are different lengths, so note where they came from. With a little
"gentle persuasion," the housing will come off. On my particular car, the PO slid it into a ditch and caught the end of the center mount bolt
which cracked the housing. This also saved me the trouble of taking off the "L" mounting bracket. It won't have to come off if you just plan
to replace the seal. The seal is easy to get to and *looks* like you could pry it out with a screwdriver, but I have never tried this. You're
going to end up with a roughly 6x6x8 inch housing which you can work on at your leisure. If you don`t have the tools to remove/replace the
bushing, you can just bring the housing to almost any auto service shop and they will be able to press a new one in for a few bucks. Plan
for about 2 hours under the car to get it out. If the gods of rusted bolts are on your side, it could be done in 45 minutes or so, I'd guess.
Nothing is particularly difficult about the operation. Although I recently told someone to shoot me if I ever said it, "installation is the reverse
of removal" (BOOM). See orientation notes below. The center flange bolt only holds the flange to the shaft; no pre-tensioning or any of that
other technical stuff.
[Procedural Notes from Bill Lauber:] Volvo AW70 Rear Bushing Replacement
Regarding Volvo Automatic transmission AW70 rear bushing replacement ...I found significant play in the end shaft and proceeded to get
the parts from my local Volvo dealer. The bushing was quoted at $36 with the seal at $11 and the gasket for about $5. I checked the
yellow pages for a automatic transmission parts house .. found one and learned the following. They carried every thing I needed, the only
difference being I carried the parts out for a total including tax of $9.70. A entire rebuild kit for the Volvo automatic was quoted at $108.00
and the dealer said the Volvo AW70 was one rebuild an individual could be successful with. I have installed the bushing, seal and gasket
and all is working well.
Procedure:
I used drive on ramps at the rear wheels not the front. This keeps excessive loss of ATF fluid when removing the rear housing. HINT, with
front wheels blocked from rolling, elevate one side of the rear all to allow rear wheel to spin on one side. This allow all to spin for easy
access to drive shaft bolts as long as the transmission is in neutral and the emergency brake is off.
1. Place support under transmission pan that can be raised and lowered as needed A board between the support and pan will help
distribute the weight normally handled by the rear transmission support which has to be removed.
2. Remove rear transmission support bolts from car frame and end of transmission and remove cross member
3. Disconnect speedometer hold down bolt at transmission then unscrew cable from transmission
4. With transmission in neutral, disconnect end of drive shaft from transmission
5. Insure transmission is in park
6. Remove transmission shifter link’s rear pin ONLY allowing link to move out of the way
7. Remove 30mm bolt from rear of shaft on transmission. Remember step 5 ... pull out shaft end
