was told trani had "small leak" approx 3wks ago. 4 days ago while driving approx 35-4-mph, engine began to "drag" and vehicle wouldnot accel.Pulled off road, check fluid level was normal. Drove vehicle approx 5mph and then parked it. Burning smell noted afterwards.Do I need to replace trani? Last fluid and filter change was @100,000mi.

have a trans shop look at this. a burning smell can't be good. Unfortunately wen you get around the 100,000 mile mark fluid should only be added as new fluid eats the glue off the clutches inside the trans. You may need a rebuild.
