Thread size for tranny drain bolt

[RyanJ]

The title pretty much says it. I need to know what size the threads are on the bolt to drain the tranny fluid for a 1991 1g n/t . Mine is stripped, the bolt and the socket it goes into, so its leaking like a mofo. I need to fix it quick. Help please

my 91 awd is 15/16.. Not sure if it's the same size for your trans.

I'm pretty sure it's 14x1.5, same as the oil pan.
