Trans Output Flange Swap

Thanks! Looking forward to getting this done.

Just wanted to verify the small and large flanges swap, I just resealed my trans and while I had the small flange off I mocked it up on the 260/6 waiting in my garage. Also, I used an impact with a portable compressor and had no problem getting either flange nut off. I used this socket and it worked perfectly.

Yeah heat was key when I did it also. Used a plumbers torch and electric impact if I recall.

Already ordered a new locking washer. Going to take them down the street to a shop with a monster of an impact gun to do it. Don't want to get hung up when it is go time.

I had to take one off at the junkyard and
a propane torch is what I used. Heat that nut a TON.
Leave it on there till it gets red. then smack the breaker bar with a heavy pipe.

An impact wrench will just zip it off ez.

Don't forget to take put in a new locking washer. You NEED it.

Plumber's torch and a cordless impact or air impact.

Ok cool. I have had a leaky rear main seal since I bought my car. We tried to get the flange off but snapped a snap-on spanner in the process. So I just let it leak. Hopefully I can get it off though. Thanks guys.

It can be an absolute BITCH without planning. Ive snapped so many tools trying to get mine off. You will need heat and a huge breaker bar (if it has never been removed before). One time I pulled one off that was finger tight lol. Ive always done it out of car which is a bitch becuase you need to find a way to hold the trans from twisting so in car is probably a better option. Ive heard people have had sucess with big ass impact guns, but I dont have access to one so I had to man up and muscle it off. Good luck my dude.

Yeah it will fit just fine. I just did a 5 speed swap and had to swap flanges also.

I have been reading in this section for a while and a few people say they have done it but there really isn't much info on it.

I have a Getrag 260/6 to go in the car, and a Getrag 260 that is in it now. From what I have gathered, I believe they are the same transmissions with different bellhousings and output flanges. If I recall correctly, these flanges are removable so you can get access to the rear main seal. So in theory, I could just swap over the smaller flange without a hitch. Right?

This way I can use my stock driveshaft and not have to worry about buying a different one. I just don't want to get down to crunch time and have it not work. This just sounds like the easiest solution to me. Anyone care to chime in?
