Leaky transmission, '89T2

[classicauto]

I've got a leaky switch on my transmission - not sure if this one is the 5th gear/reverse and/or neutral switch, but that's not my question (consulting the FSM will answer that one). Here's a couple of snapshots of the leaky switch I'm talking about. You can see the bead of oil about to drip at the end by the wires. Note also the lack of clearance available to get an open end or box wrench over the hex switch body. A VERY deep socket might work, but the wires would get in the way.

My question is, how do I get this thing off to fix the leak without dropping the transmission? Looks like my only wrench access is from above, and the trans tunnel makes that all but impossible. Any ideas?

Thanks,
Pete
