I've got to replace the backup/neutral switch on a 1998 5spd since it's leaking. Anything tricky about this other than the one phillips head hex-head bolt to remove it?

I'm going to replace the fluid with MT-90.

Also Where is the actual drain plug located? I've found the big fill plug in the front.

Are there gaskets on the drain/fill plugs?

Thanks

its pretty easy- one bolt to remove. the backup/neutral switch is by far the fastest way to drain the tranny. it's gonna be a gusher, so be ready with a drain pan.
on mine, the wiring harness went through the main transmission mount so i just cut the old wires and routed the new ones around to the plug in.
beware-there are a few of us who found that the leak was actually coming from the half-shaft and was a sign of failing differential bearings in the tranny.

 

Thanks. I got a replacement sensor for $20.00.

Do you know where the real drain plug is also? Usually there's a magnet on it that I'd like to clean off...

Also regarding the driveshaft leak, which one seems to fail? The outboard/drivers side seems fine. I can't see an obvious leak on either shaft....

once under the car dont be afraid to keep on getting further in (coming from the driver side) not the front of the vehicle and your gonna find it.

 

It's near the shifter input to the tranny, facing the engine. See here:

I guess you're replacing the backup switch, but anyway be very careful when removing it - the plastic flange is quite brittle. Twist it out since the o-ring has a pretty good grip on the housing; don't insert a screwdriver and twist. (ask me how I know )
