Took my 98 Disco 1 to the gas station and filled up the other day. Pulled out and speed up to about 50. Then the trans felt like it went into neutral and I had to coast into a parking lot. Then none of the gears would do anything. Like it's in neutral all the time. There are no abnormal noises. I put it into diff lock and low range no change. If I start it up cold it works for about 30 seconds forward and reverse. Then nothing.

I was was wondering if anyone had any experience with this symptom. Maybe trans pump or torque converter?
