Great video! In my opinion, you have the best Volvo maintenance/repair videos on KZbin. I have referred to them many times. I flushed and filled the AW70 transmission on my '90 740 GL last fall using the same method with excellent results. Btw, I have the same interior as shown in this video. I recently snapped off one of the 2 bolts holding the overdrive solenoid to the transmission. The solenoid was working fine but showing signs of corrosion and plastic deterioration. I now have just one bolt holding the old solenoid in place. (I didn't attempt to remove the second bolt to install the new solenoid for fear of snapping that bolt off, too.) I see no way of drilling out the broken bolt without removing the transmission from the car. Do you have any suggestions or thoughts? Thanks.

[@robertdeptula2003]

Thanks for your kind words. As for the solenoid, I am afraid, dropping transmission will be safer option. If the bolt is burred inside, drill and extract. If a part of it is sticking out you will have more options, but do not use heat to remove it. Too much oil in proximity. And remember that when you remove the solenoid, a substantial amount of ATF will come out. Good luck and let's keep them rolling.

@@robertdeptula2003 Thanks for your reply and thoughtful advice. Until I decide - or really have to pull the transmission - I plan on just leaving things as they are. After the bolt broke off I managed to reattach the head to what was still in the hole (there was none of it sticking out to grab) using J-B Weld. I made sure to use enough J-B Weld so that some spilled out under the washer and head to secure it to the base of the solenoid. Between the corrosion from the old bolt and the J-B Weld I am hoping that it will be enough to hold that end of the solenoid in place until it absolutely has to be replaced or the transmission absolutely has to be pulled.

One more question do you drain from the pan underneath because that fluid is possibly dirtier or has sludge? Also does the pan have a plug with Allen socket or is it a regular bolt. Do you use a crush washer?

[@robertdeptula2003]

I drain the pan. There was regular bolt. And yes, crash washer.

[@stevendwoodruff]

Thanks vrry much. If there was regular atf in the car should you add only the same kind of fluid?

[@robertdeptula2003]

Use ATF fluid that is required for your car. Check owners manual. Mine was DM and I used synthetic that was within the spec.

Great vid!!

When is it necessary to change the fluid? I recently acquired a 1994 940 with 261k miles

[@robertdeptula2003]

ATF should be ruby red, if it is discolored, then it is time to change it. At the first signs of transmission slipping or hard shifting, time to change it. At your mileage I would do it. Whatever you decide, do it at your own risk. Good luck!

[@TerminatedEfficiency]

Would it be the same procedure on a manual m46 transmission on my 740?

[@robertdeptula2003]

No. Manual transmission is simply drain and fill. You have two plugs in manual transmission, the lower is to drain, the upper - to fill.
