Hi everyone, wanted to see if could get any help. I have a 1994 Automatic with 105K miles. One day when I was driving and the car was acting very sluggish and I had to rev pretty hard just to get up to 30mph. I had it towed to my mechanic, and he said he's been driving all week with no issues and is telling me to pick it up. Wanted to see if anyone might know what caused this issue. I'm just worried 2 days later after I get it back, transmission will go out.
