I dont know a whole lot about transmissions. When i had the motor out, i looked at the transmission. It looked fairly new. The front pump was nice and shiny, no leaks from anywhere. I drained my fluid and dropped the pan about 10,000 miles ago. The old fluid was red, not burnt at all. So Ive been under the impression thats its a good, newer trans. The other night, It started to slip. The fluid level is perfect, and the newer fluid is good. But what puzzled me was, it doesnt slip from 1-2 manual shifting, but it will slip from 1-2, 2-3, and 3-4 in drive. What are the odds of that? Im thinking one of the solenoids is on its way out, but like i said earlier, im not a transmission man. Can anyone help me out?
