Let me elaborate,
I overhauled this car last year. I did a head job (myself), after first having the flywheel replaced, due to an ignition problem. As I was putting the heads back on, I noticed the heat shield was gone. I consulted the guy who did the flywheel, and they said it was gone when they did the job. (I believe them). So. Before I put the back exhaust manifold back on, I folded a pie pan around some fiberglass insulation, and mashed it overtop of a brand new Vehicle Speed Sensor (VSS). Then I put the 1,2,3 exhaust manifold back on. I drove the van for 15K mi with no problems. Now I've got a P0500 code, and the van doesn't seem to know when to shift anymore. The VSS is easy to replace (1 bolt, 1 wire clip) but only when that 1,2,3 manifold is off. I am looking for a "slick" way to replace that puppy, without having to pull the rear Exhaust-pipe.
