Rough downshift on powerglide 2 speed automatic

When the engine and driveline are cold, I get a rough, jolting downshift into neutral as I approach a stoplight. As things warm up, it tends to go away but it is still perceptible. It only occurs from low gear to neutral, though there is a little jolt when shifting into drive too, but nothing like the down shift. Engine is a 283 factory stock.

Do I check the fluid level with the trans. hot and the car running like a modern automatic? And if the fluid is OK, could this be a weak spring on one one of the shift points?
