Don’t Break Your Transmission!
Transmission Drain n Fill vs. Flush
Real world advice from Volvo owners who have done one or another – and the results.

Speaking from my personal experience, it will take all the crud that may possibly be holding the trans together(ie the grit from the clutch plates) and rinse it all out. then the fresh shiny new innards of the trans are scrubbed clean of what was making it hold, and it begins to slip in a most horrid way. I found this out th hard way. NEVER FLUSH A HIGH MILEAGE TRANS!!! I got lucky and found a 78k unit at a local salvage yard, and with the istall I’m only gonna have @ 700 wrapped up in the replacement. I know I could have done it myself, but I lack time and am scared crapless of front wheel drive transmissions. i’d hate to break something and have to hear it from the wifey. 
Transmission Flush not recommended for 850’s

Thank you Matthew! I am trying to teach myself to work on the volvo s70 because I can not afford to buy another car, and I do have experience as an aircraft mechanic. Your posts are most helpful! Candace
