Default Transmission cooling line banjo bolt dimensions?

Ok to start off... I hope I haven't failed with my searches , but I cant get the answer I need!

I have a 2002 accord 2.3l that I just changed the transmission, finally back on the ground start it up and the trans cooling line is leaking...
So I think no big deal maybe I just didn't torque it down... well after attempting to torque the banjo bolt the leak was MUCH more intense and wasn't locking in.
I then removed the line and bolt to find out that the top 1/2 of the threads inside the transmission were stripped... bare!

I am really hoping to get the thread/pitch/length of this banjo bolt, and wanting opinions on my potential fix!

I plan on finding a matching banjo bolt that is a 1/8 to a 1/2 inch longer to see if that will possibly get the line to seal, and eliminate the leak ( without heli-coil, thread insert, or having to remove the transmission take it back to the yard pull another and reinstall fingers crossed i find a gem similar to what i have already installed.)

Any input or help would be GREATLY appreciated i picked the car up super cheap for a beater, and im ready to get this thing on the road!

there should be two washers, they are the crush type, you have to replace them each time you take off the line

The problem is that the bolt with the fitting and old washers attached will not reach the remaining threads...
theres more than a half an inch of threads past the point of what’s stripped it’s just a matter of finding a longer banjo bolt to grab the threads.

bump!! Help please

When checking the threads of the bolt it’s giving me 1.5x20 but When checking part stores they say they can’t get one...also no helicoil kits in that size either :/

It is possible to buy banjo bolts of different lengths. I found this out when adapting Advics calipers to Accord fittings.
