Port on top of trans...

[GTPrix]

I will be uninstalling my trans temp gauge soon.

When I take off the temp. sending unit, do I need to replace a plug on the top port of the trans? It was a few years ago I put the gauge in and I cannot remember if that goes directly into fluid. TIA

Yes you will as that is a testing port and it will cause a tranny fluid gusher if not plugged.

Does anybody know what I can use to plug it if I don't have the OEM plug anymore? I assume it is pipe threads but if someone has the specs that would be cool.

I dont know what the size of that thread is, you best bet is to contact Trannyman95 and see if he can give you some insight.

Where is the transmission test port located?
