My 82 cv has the aod tranny. My mechanic said to keep it in drive while around town, but I find if I let it go into o/d at about 45mph I get much better gas mileage. I don't stomp the pedal while driving that slow in o/d.
Is this Ok for this tranny, or is it better to save the o/d until up on the highway?
While driving in the city from 0-55 MPH drive in D, and when driving highway 55+ MPH drive in OD. Trust me you will prolong the life of the OD of the tranny and it is also stated in the owners guide to drive this way too.
By leaving it in OD, you're allowing the transmission to shuffle between third and fourth gears and believe me, it will. Burns out the overdrive band a lot faster, from what I hear.
