Hey guys. I'm trying to change the transmission oil on the RX7 I just bought, and I got the drain bolt out just fine. The fill bolt, however is stuck.
Any tricks on getting the fill bolt loose,
or failing that any other bolt I can remove so that I can add some oil to my transmission? If I can get oil in there I can just put in a measured amount, instead of going to the fill line.

 

I had this problem with my rear end. Turned out the previous owner had stripped it and welded it in.

 

big *** crescent wrench if it's the square type. Might be able to use a 12pt wrench (I think 16mm) and double wrench it.

 

You can try a pipe wrench if the plug is rounded off. If all else fails you can remove the shifter and pour the lube in there.

 

just pull the shifter out and pour it in there.

 

^I think that only works with the earlier cars ('79-'80). His profile says that he has a '83, so he has a remote shifter. I don't have anything to add with regards to getting the plug out. A lot of good suggestions have already been given. Good luck.

 

*laughs* pipe wrench!

I did try a big-*** crescent. No luck though. I've been searching for a 4-point socket from anywhere for the last several hours to no avail.

I might just try the pipe wrench idea.

 

Turn a 6 inch 3/8 or 1/2 extension backwards and slip it over the plug. Also hit the plug on the end with a hamer a few times before you start. LOL.

 

sorry, didn't look at his profile before posting. that was just my first thought. i'm using an '83 tranny, but i moved the shifter back up, sorry bout that. the pipe wrench should work if all else fails.
