My Dad just bought a '94 15 pass van w/ a 454 and 4L80E. It's got 411's in the rear right now and he's probably going to go down to 373's or something less to gain back some highway drivablility. My question is this...Does anybody know how to fix the speedo on this on. I'm thinking gear swap on the tranny speedo drive gear, but not having seen this van, I'm not sure if that's what needs to happen, or is the speedo driven by something else on a '94?
