i got a 67 last week but now the heater core is leaking and the tranny doesnt work in reverse fluid is full any help would be appreciated

 

I to have a 67 mustang. Let's start with the heater core first. It will need replaced. Here is a link to one at a great place. http://www.karmustang.com/search.php?mode=search&page=1 (you will have to scroll down) I don't know where you live but I live in Ohio and this place is just a short drive to Columbus to get any part needed. The problem that you will have is you will have to cut the heater hose to get the old core out. Then you will have to replace the hose too. And now the transmission. The bad news is the transmission will need a going over by a transmission shop. I just had to rebuild mine. I have a local shop I take mine to. It would have only been $325 for the rebuild if it weren't for the extra $100 for a new torque converter. I thought that it was vary reasonably priced and with a fast turn around. Sorry to be the bringer of the bad news. Trust me I know how it is.

 

Thanks for the info and I actually expected worse when I bought it the frame is in great shape and there if no rust on the structure just small ones on the quarters

 

Mine has lots of the rust. Transmissions are not hard to take out. If you do it your self you will save at the least $100. The only special tool that would really help is a transmission jack. I just have a $50 adapter from jcwhitney that turns a floor jack into one. You can also use a motorcycle jack if you or someone you know has one. The transmission is cast aluminum, but still ways almost 200lbs. Here is a video of some people taking one out. The main thing is support the engine with a jack with a piece of wood on it jacked up until it is touching the oil pan. If you don't do this the engine and transmission will swivel down at you when you take out the crossmember. It would also dent the oil pan up real bad. The jack with the piece of wood won't hert the pan. I don't mean to scare you. Here is a link to a video on YouTube of someone taking their transmission out of their 64 1/2 mustang. http://m.youtube.com/index?desktop_u...?v=VSqebRmcVYc If these people can do it I bet that you can. As you will be able to tell from the video they don't know to much about cars.

 

Before pulling the transmission to have it rebuilt, have you checked the vacuum line going to the modulator? How about the modulator itself? When was the last time the fluid and filter was changed?

Don't just throw money at it!

For the heater core, not much choice but to replace it. You might have enough hose to reconnect, but new hoses are cheap. While you're at it, buy the heater case rebuild kit which will come with all new seals, etc.

 

as far as fluid and filter i have no idea. where are the modulator and vacuum line. im new to the classic cars and am only 29 so i have alot of learning to do on it.

 

Well I'm 16 years old and I rebuilt the engine in mine, and removed the transmission and had it rebuilt. The vacuum modulator is a small brass bell shaped part on the passenger side of the car attached to the transmission case. Here is what one actually looks like http://search.yahoo.com/mobile/s?rew...id&slider=open Then the transmission fluid. You will need type F transmission fluid. This type is needed because back in those days machining wasn't that great. Type F transmission fluid is basically gear oil to prevent wear on rough machined surfaces with imperfections. You will also need a gasket for the pan and you might as well change the filter. The filter you will find when you remove the pan. There is a certain way to get the fluid out with out spilling it every where. You loosen the bolts on the pan about 1/4" break the pan loose and let the fluid drain some into a pan. Then you take it off the rest of the way and poor out the fluid. Once you have the pan back on with the new gasket. You poor 3 quarts of fluid in through the dipstick, then you start it up, shut it off and then add 3-5 more quarts. If you try to put it all in at once it will try to blow out. I hoped that this helped.

 

You should replace torque converter if rebuilding transmission as you cannot get all of the trash out of them. Cheap insurance.

 

not quite lol, the c4 tranny in mine weighs like 50-70 lbs

also if the engine has not been rebuilt you might want to do it, its easier to pull the engine and tranny at the same time, all you need is a engine lift/stand bought both for less then 300$ at harbor freight.
