Yes in 1991-1993 the Lumina Z34, or Grand Prix 3.4, could get a Getrag 284 5-speed. It is a very rare, and VERY expensive option, but IMHO well worth it. The car is lot more fun to drive, and a lot faster.
I've owned 2 5-speed Z34s, sold the first after modding it pretty far, and keeping the second for daily driving. The car is too big and heavy to race, and can't handle worth a [censored]. So I did what any normal person would: Bought a Fiero, swapped in the Z34 engine, modded it to hell, and hunted down Z06's
