Hello Gents! I'll describe my situation here and please let me know what the collective mine thinks on this!
I've recently had to go on a long road trip, and in 5 months will be going on a cross country trip. In the last month I have noticed that my car has not always wanted to slip into first gear right away, and notice it most when I first start my car. Now if I can drive and sort of "power" through that little hick-up the transmission will slide into gear after a few seconds of giving my engine some power. Only at initial start up though. It appears once my car is fully warm and been driving, that say if I stop at a light and am still in gear there appears to be no problem pressing on the gas and going. So slipping, no stuttering, just easy going..... I heard from one of my buddies that sometimes if the transmission oil is dirty it can cause some problems in the tranny. Well today I'm going to get it flushed, but if that doesn't work, where can I get a good transmission? OR can this one be rebuilt?

Well thank you very much, and I can't seem to get a hand on this.... but we will see.

Steven

Don't forget Steve, that you have 4 or 5 quarts of dirty fluid in the Torque converter. It takes about 13 or 14 quarts of fluid to properly flush a C4 and the torque converter. If that proper flushing and tightening of the bands doesn't work, then yes, you can get that tranny overhauled at a much cheaper price that buying a performance C4 off the internet.

So if I take this to a transmission shop they should be able to do this adaquetly? Or how will I know if they did a good job? So dirty fluid does cause problems in the C4 Transmission?

Soaring · « **Reply #3 on:** May 24, 2009, 05:09:26 PM »

Absolutely....Tell the the transmission shop to not only drain the pan from the C4, but to also drain the torque converter, clean the filter and add the proper amount of fluid. Tell them to also adjust the bands from the outside of the transmission. They do not have to take the transmission apart to adjust the bands. It only takes a few minutes and shouldn't cost any more than a few minutes of labor if they are competent. If not, then move on to another transmission shop where they are competent to your request. You have my permission to print this and take it with you to the transmission shop. Make sure on the phone prior to taking the car to them that they are competent in working of Ford C4 transmissions, otherwise they will be clueless.

Is there anything different I need to say, for my transmission is an automatic one..... Just making sure in case there is somethin else I need to do....

Soaring · « **Reply #5 on:** May 24, 2009, 05:28:26 PM »

A C4 IS an automatic transmission.

Man, you are wet behind the ears, aren't you?

That's O.K, you are in the right neighborhood to get the information you need to enjoy that classic. Educate yourself, and demand good service from the transmission company who works on your C4 AUTOMATIC transmission.

Of course! I'm only 21! lol. This is my first car I've ever had to work on, and I LOVE working on her, I think the transmission is a little beyond my knowledge base right now, but I've learned a LOT about my car and many other years and makes of the Stang love. I will make sure I copy down all the things you told me to tell them to do. lol. Thanks for the help, really appreciate it*

No problem, just don't let any advertised transmission shop work on your transmission. Make sure they understand that you have a C4 in a classic Mustang, and that the transmission will not be taken out of the car, that you only need a COMPLETE fluid change to include the converter, and that you want them to adjust the bands. If they can't do that competently, then move on to another transmission shop.

i recently read that its possible to put overdrive in the trannys. could i put the overdrive in the c4 tranny without putting a new one in and make it look the same even for a show? or...? also, is it possible to view the options a vehicle had with the first owner via vin?

Soaring · « **Reply #9 on:** January 14, 2010, 11:21:12 PM »

Go to the FAQ section and read up on how to put in an overdrive. It's under the transmission section.

Like Soaring said you need to find a shop that knows about early ford autos like the C4. It is not rocket science, but you will not get what you need at one of those quick change oil places, unless they have a real gearhead working for them. Contact your local mustang or ford club and ask for a referral. You may find someone in the club that will do it with you. If you lived near me I would show you how it is done. Whole operation should take no more than 1-2 hrs max. Make sure they/you drain the converter, if you don't it will almost be for naught.

i mean would i be able to put the overdrive equipment into the existing c4? or the bellhousing at least so it at least looks original?

No....read the article....http://www.mustangsandmore.com/ubb/DanJonesC4AODswap.html

damn

oh well. anyway, last time i took her out i noticed the ignition started to stick. what would possibly cause this? also i sat watching my spedometer while warming it up, it i guess you could say moves erratically. ill try to get video of it this weekend. and finally i tested my windshield wipers as well and they dont exactly move much n when they do its kinda slow even when its on high. that cant be normal

Tim175 · « **Reply #14 on:** January 15, 2010, 08:58:57 PM »

Sounds like the wind shield wiper motor is going out. When you say the ignition is sticking, do you mean the starter is staying engaged or is the turn key actually sticking when you start the car? If its the turn key then you might need/want to just replace the ignition cylinder but i don't know for sure.

Soaring · « **Reply #15 on:** January 15, 2010, 09:47:06 PM »

Yeah, gunk builds up in the ignition key cylinder over the 40 or so years, and that's why Mustang supply stores sell new ones.

They also sell new windshield wiper motors. You have to keep constantly replacing these parts to thes old dinosaurs. Fortunately, we have supply companies who can supply us with these parts.

Glen is right these 40+ year old girls need a little/lot of TLC. My 67' suffered from the same two problems. I did replace the windshield wiper motor and took apart the washer system that was loaded up with 43 years of gunk. But happy to say after I was done worked like new.
As for your second issue, my car would continue to crank after I released the key, it was my starter relay(solenoid) an easy and inexpensive fix...

Good luck.

Jeff

I have a spray designed to clean electrical connections. You could insert the little red tube in the key hole and try some of that to loosen up some of the gunk. You might could even get by with WD-40. Give that a try before replacing the ignition switch.

mustangluver · « **Reply #18 on:** January 16, 2010, 02:51:51 PM »

on the ignition, when i turn the key to start it stays there. also when i used wd40 it stripped the paint off my dash. so i got lock grease a while back n imma use that. also do any of yall have issues with gettin the trunk open? i have to play with the lock on mine.

Soaring · « **Reply #19 on:** January 16, 2010, 03:12:57 PM »

That old trunk lock is wore out too.

Get a new one, and also order it with a key. Sorry about the WD-40 peeling the paint off your dash. Once you get all the mechanical stuff working, you can repaint the dash. That's a weekend project, but it probably needs it anyway.
