I am interested in doing the same thing. I found the post below doing a search on VSS. Note I have not actually performed the VSS replacement, but the instructions below look good to me. Although I don't relish doing this on my back with the car up on ramps. I guess I'll try and replace the O2 sensors at the same time, since one of them is in the same vicinity. To get to the VSS from the top I think you'll have to sprawl across the intake mainifold.

You definetly don't have to have the tranny out to do this. To find it just follow the speedometer cable down to the tranny housing and that's it. It is what the speedometer cable plugs into. The speedometer is held in by a pin that you just pull out.

Please note: The instructions that I am going to give you will give you an idea, but you do not have to remove the Y pipe. If you take off the intake it will be easier getting to it from the top. Also note that these instructions are for an AX4S, but all the ATX's have the VSS located in the same place. On the MTX-IV It's even easier, just look at your thermostat housing. The VSS is 6" closer to the firewall and down.

Cool thanks man!!

I tried to replace the VSS without removing the intake or the exhaust..........forget it. Looks like I will have to **** up the old exhaust studs, and try not to snap em'. Good luck to all that try. Most shops want about 300-325 bucks.

Don't forget it man. There is a tool for everything. You are obviously lacking the correct one. Get your ass under there and have at it again. I've done plenty with the exhaust on.

 

[Bluto]

Its like searching for a rainbow in the dark. I just could not get in there. Your right there is a tool for every job, but I lost my telascopic eyeballs.

I guess if I don't try again I will never get it.
-Thanks

Bluto, how about a telescoping mirror to get a good fix on it? They sell them at the autoparts store cheap.

Mike,
I think I can do it. Especially since I will be removing the intake soon to switch plugs/wires. I will keep you posted, and if I run into a snag, can I call you? Thanks for posting this..
