I've read for a long time that you can "Split the Gears" on GV od's & they make your trans "8 or 10 Spd", but can you really PROGRESSIVLY shift thru the gears, or is it just being able to split the gear your using?
Kinda xample of what I' talking about is like a Fuller 13 spd & a 15 speed.
The 13 spd has two ranges, and you split the last 4 gears, all progressive & only use 1st once.
However the 15 spd has 3 ranges & 15 forward spds, but you shift it either 3-5-5 or 5-3-5, so it only has 13 PROGRESSIVE speeds.
