Leaky transmission, '89T2
 

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

You'll have to drop it to remove that little guy.

I would first make sure that its not leaking from above (shifter tower) and running down though.

FWIW, I am sure I've used a socket on one of those before but it was on the ground (i've only ever swapped them out while swapping in later model transmissions) but I'm sure had a deep enough socket to pile the wires in and ctach the end of the hex portion with the socket.....

Thanks - After thinking about it some more, I suppose a 3/8" drive crow foot on an extension would do the trick, but I had no luck finding one big enough - looks like somewhere between 28~30 mm. The shifter tower is dry, as is the rear seal - when that thing leaks oil goes EVERYWHERE!
