reverse light switch on transmission
 

I have a brand new reverse light switch and harness from honda. I need to remove the old switch from the transmission (which is a integra 90-93). My question is, is there going to be transmission fluid behind that switch? I need to know this so I have something to catch it, and allow time to refill the transmission.

The helms manual doesnt make mention of it, though there is a gasket. On D series motors, where the switch is on the top, you can fill the transmission from there. So I wonder, is it the same case for a B?

This should be such a simple project, but I have a feeling its going to be messy.

just prepare for the mess. On my accord i could change axles and not lose one drop of tranny fluid, while on the integra i lost it all.
