its a k series 4 speed, it needs a speedo cable the original doesnt match the box but they are not to hard to find just havent had time, and it needs a water temp swith because the metal terminal where the wire connects to broke off, its running a thermo fan which cuts in and out depending on the temp... the only real concern is a hole in the sump where a mount everist speed hump came in contact with it, iv plugged it with quick steel which is fine for now.... i would reduce the price to compencate for minor problems tho..
