His 5speed tranny died and I suggested he replace it with a 6 speed. The 6 speeds are easier to get used and they do not suffer the problems the 5speeds did.
The swap went without a hitch, did not have to change a thing just bolted right in, only thing he needs is the 6speed shifter knob, but the 5 speed on is fine.
He loves it! Big improvement he said. Car has way more pep.
I am sure if it can be done in a Matrix it would be the same for a vibe, in fact the tranny he put in was from a Vibe
