Im taking my transmission off in a couple of days to replace my clutch. the holes where the three bolts go into the tranmission housing for the mount is stripped. what size helicoil am i supposed to get to fix this issue. This is for the mount that sits on the top side of the trans. I know someone has fixed those same threads before, i just need to know the right size before i get the helicoil.

 

the transmission is a D16z6.

 

i kno someone has done this before.

 

The studs size is M12x57.5(1.25 thread pitch). I'm unsure how deep the stud goes into the transmission, as I don't have any stock studs. I'm sure they are at least 20mm if not 30mm deep.

I'm in the same boat as you and am really starting to hate life. Who ever decided to use two studs and a bolt was the dumbest ******* alive. The hole for the bolt is open all the way to the gear sets in the tranny. I have no idea how I'm gonna get all the shavings out of the case...

 

thanks man for the size. ive been drivin a boosted single cam for like six months without that mount and now that i gotta drop the trans an i wanna fix it. lol

 

well i have a d16a sohc non vtec wit d15 trans in a 91 honda crx si. do u no the size of the trans mount bolt that goes inside the bell housing in the front? its the smallest mount under the hood, cuz mine was over tightened n stripped out n the bolts were lost on the highway somewhere n parts stores dont sell wit mount

 

i had to order a mount bolt from honda, its wasnt that bad maybe 5 bucks
