So along with a basic tuneup my friend and I decided to do a filter and fluid change on our 1991 Volvo 240 wagon. Fluid was looking pretty dark so figured it could use it. Doing it as I’ve seen in videos and read online and just from common sense of doing it before on other vehicles, the car wouldn’t shift at all afterwards. Just had park and everything else acted as neutral. Fluid level wasn’t low, no leaks, etc.

what could we have done wrong? Should we do a flush? All we did was a drain and fill with the filter so that’s all I could think of. Or we somehow did the filter wrong?? Not sure how though it’s pretty straight forward.

 

If all checks out as far as levels... Did you make sure after you added the fluid, did you move the shifter thru all the gears a few times???

Park, reverse drive etc...
This allows the passage ways in tranny/ filter etc to build pressure properly!

Was there ever a resolution to this?
