c4 transmission

I was wondering how much pressure it should take to move the kickdown lever on a c4 tranny? Right now my mustang really does not want to downshift when i step on the gas. I dropped the transmission pan and looked at the lever that the kickdown cable attaches to. I moves but i really have to pull...

im dropping a 302 in my 56 fairlane as the title suggests, anyone know of anybody doing this previously and if any mounts allowed it to just drop in without having to weld plates or elephant ears? also pairing it up with a c4 transmission if anyone has any advice for mounts there. thanks!

Hey Guys, I recently bought a 1971 Mach 1 with the 302 Windsor and the C-4 transmission. I bought it as a project car so i was just happy it ran. I was able to start it up and drive it around alittle bit but wasnt able to get it out on the highway. I made sure i could manually shift it from 1st...

Looking for some input. We are putting a 87 model 302 in our 66 coupe, just had a 70 model c4 rebuilt to go in it. The problem is I don't know what torque converter to use I have a 26 spline input shaft and the bolt space on the flexplate is 11.5. Any help would be appreciated.

Hey guys I'm new to this forum, and was hoping you could help me out with some answers. I currently have a 1966 mustang with a C4- 3 speed transmission. Its running great, however the RPMs are very high when cruising at about 50mph. Would an AOD swap help out? and can I use a transmission from...

I have a 69 coupe with an automatic transmission. I definitely want to convert to a manual in the future. Does anybody have experience with this? How should I go about it, what will the costs be around, and how hard is the labor. Is it something possible for someone with no experience and a set...

Once upon a time, I'm getting really frustrated. Where are all those people who want to buy my car right now? When it's a good thing they're not around? Okay. I have a 71 Mustang with a c4 transmission and a 1990 302. Its been running great. A few months ago, my starter broke off. Saved by the...

So i just bought a 83 with the 302 ho in it and i gotta say the engine runs great and definetly not stock. Only problem is the transmission is trashed. Well i didnt ask too many questions about the transmissiom but assumed i would just have to rebuild it. Well today i crawled under the car to...

Hey there everyone, So I am only 17 years old, and I was lucky enough to have my first car be a 1967 mustang. This was my moms car, and it has been in our family for almost 30 years now. When I got my license it was finally time to bring it back out of our shop. It has been very fun having this...

I've tried to seat my torque converter into my C4 transmission but I can't seem to get is into the front pump. I got the TC to 'click' into place twice, over both shafts but it won seat all the way into the pump. I've tried lining up the grooves, wiggling and shaking but to no avail. I have...

1967 mercury comet. I swapped in a roller cam 5.oL engine. It came with an automatic transmission. I had the C4 in place for only a few weeks, then upgraded to an AOD for the overdrive gear. Now, I am left with a 50oz balance flexplate for a C4. I am looking to sell it. If you are interested...

I am replacing the transmission cooler lines on a 64 1/2 coupe, and can't figure out which lines I need to order. My car is a 1964 1/2 coupe (built July 29 '64) that has a C4 transmission with the following casting number on the driver's side: C4AP 7A040-C From what I can find, it's from a...

:headscratch: I'm building a 302 up to 300+ hp. I now have a c4 transmission. Currently looked at a fmx for 200.00, My c4 for does fine now but, I was told its not going to hold up to the build. I was told the fmx would but I dont know if it has to be rebuilt. What should i do? Buy a new one, if...

White smoke and engine running rough. I changed the modulator and vacuum line. Took it for a short drive to test and burn off the spillage of fluid. I am still getting some smoke, but not as much. The engine is still a little rough, especially at idle. Transmission is shifting much better...

We purchased a 289 with a c4 transmission off of a 1965 Ranchero to replace our "Frankenstang" 302 with Nissan transmission. We noticed that the transmission lever on the Ranchero c4 points down, while the Nissan trans lever points up. The Ranchero was a column shift, while the Mustang is a...

Just bought a 1965 Mustang with a C4 Transmission for my 15 year old son this past Christmas. There is a knocking sound. It is like a rod nock, but I dont think it is. The sound speeds up as the RPMs increase. I believe the sound is from the bolts that connect the torque converter to the...

as i was getting home from work this weekend i went to put my 71mach 1 in park in the driveway and it wouldnt go out of drive. it shifts between 1st and D fine, but refuses to go to park. i have checked the linkage and fluid in the time i've had to work on it, but thats all good. Need some help...

I have a 1985 Mustang C4 transmission. I want to replace the gear selector/shifter seal in the transmission body. I have read a bunch, have the valve body out, but am not sure how to loosen the 7/8" nut correctly. When trying to loosen the nut, it pushes on an arm connected to the selector plate...

What do you guys think is the best shift kit for a 68 C4 trans? The trans is hooked to a 289 4v in my daily driver, so I don't want to go too extreme with anything. I've got it between either a transgo stage 2 kit (TransGo Performance 47-2 - TransGo Performance Shift Kits - Overview -...

I have a 289 c-code engine (backed by a C4 auto trans) that I am looking to increase the performance on. It's actually in a 68 Falcon, but since it was also a Mustang engine/trans, I figured you guys were the ones to come to for info. Right now it's not anything special, at least not that I'm...
