By what I can gather, a synchromesh manual transmission fluid is what's called for. It's not ATF. But a motor oil (synthetic fine) can be subbed.

From another thread-

"Chevrolet Truck 1988-92
5-speed: Sectional Case
Gear Lubricant = GLS P.N.1052931 (This number is listed in the book) (Gear Lube,Special)
Cross reference - 5W-30 or 10W-30 Engine Oil SG/CC/CD

Capacity should be 1.9 qts., check to make sure by saving the drained oil and measuring it."

And-

"New Venture Gear 3500 Manual Transmission recommended lubricant: Synchromesh transmission fluid GM p/n 12345349
The oil capacity is 2.2 quarts or 2.0 liters."

The Amsoil site calls for 5W-30 synchromesh transmission fluid in all manual transmissions for that truck except the NV4500, which your truck won't have anyway.
