Nissan Sealant? (OE part # KP610-00250)

[s73]

had a slow leak from my 92 240sx's trans, seems to be from the sensors, after a bit of researching in the service manual, it recommended sealant on the treads of the sensors before install. I am thinking about taking the sensors out and clean/reapply sealant to see if it help the leak issue.

Any body knows what kind of sealant to use that is equivalent to Nissan part number kp610-00250?

also......anybody knows where to find GL-4 MTF? cant seem to find it in any stores!

anybody else have this leaking issue please provide me some info! this trans leak is driving me nuts!!

thanks in advance
