Hi all. Got a serious question here and hope i dont get the bad news im thinking im gonna get. My sister has the 98 sebring conv with the 2.5 v6 and today she called me to come get her. She was 10 miles from home. 8 miles was freeway. She said the car was reving up on the interstate doing about 60 and not pulling. I asked her if it had just started doing that and is that why she pulled over. She said no that it had been slipping like that since she had left house. I asked why she kept going of course and she said this- "i thought maybe it hadn't warmed up yet". Typical. Anyway, I get to the car and its low on transmission fluid. I put a quart in and now theres too much. So i crank it up and put it in reverse and nothing but reving to 3 and 4k rpm's. Then all of the sudden it snatches itself into gear and starts backing up. I stop and put it in drive and nothing. 4k rpm's. Then again, bam, it goes into gear and goes forward. It does same in all gears. D,L,1,2,3 and reverse. I should mention its the auto stick. The instrument cluster doesnt have the auto stick showing, it has the same as a regular transmission. Weird. But anyway, thats what the details are. Im having it towed to my house as I type you all this. As always, any help, advice and direction is always APPRECIATED, thanks, Marc C.
