Overdrive slipping?
Reply #8 –
A girl I was involved with had a '93 Cougar the same time I had my '86 Cougar. Of course, red fender was always leaving me down, somewhere. Well, her '93 started doing like you described. Next thing you know, it wouldn't go ANYwhere. Well, I check the transmission fluid & the stick is DRY! So, we proceed to the autoparts store, where I grab 5 quarts of transmission fluid.
I dump four in, and the car starts working like it's supposed to. So, we get it to a shop her dad told her to bring it to so it can get worked on first thing Monday.
Well, that Monday, they dump NINE quarts out 

So, after conversing with Eric, the OD band went bad. The only reason the trans dip stick was dry was because it was checked facing up a big hill. If we'd have just put her car in drive, we could have gone anywhere we wanted to.
That's how I'd know you burnt up over-drive :(
As a post script to the story ...
Her dad was a construction worker. Every bit of 6' 5" and 300lbs of muscle. Well, he wanted to wring my neck something fierce. In fact, this girl told me not to show up at her house, 'cause her dad was pissed. Her mom explained to her dad I was just looking out for his little girl. After momma told dad that, and it sunk in, I was his best friend in the whole world. shiznit, I got to drink through his case of beer, if I wanted to
