Description: Custom Knight Rider 15spd & 18spd transmissions for Vipers Peterbilt 389v2

Both transmissions built to handle powerful engines & standard engines with practical characteristics on-road. Gives a better experience using powerful engine mods if you still want to drive fairly well at higher speeds. Maintains acceptable driving characteristics with medium weights & standard engines.

Checkout my vid to see the 15spd (KR15-R Fusion) trans fitted to Vipers 389v2, along with my custom engine/sound, 6x6 heavy chassis & moving van skin mods. Flying like a bat outta hell at 450kph+ (no bailing).
