C4 original or t5 automatic?

RoyLovezSublime · 02-07-2005

I currently have a 67 mustang that still has its C4 automatic transmission, that it came with way back when it first came out of the factory. My question is whether I should replace the C4 with a T5 maual, and if that would demte its value... i have a V6 200ci engine...

I don't think changing the transmission would hurt the value of your car because you can always take the transmission out and put the stock one back in! However, swapping an auto car to manual takes a bit more effort. But that too could be put back to original if it was necessary. Its just a matter of your opinion on which trans. you want to use. :thumbsup

Well, my 2 cents is I would never buy a car that is converted to a T5 or anything that wasn't stock. If you converted an auto to a 3-speed manual or 4-speed Toploader, I wouldn't mind, but I wouldn't consider a car with a T5, even if it was being sold for $20.

T5's are sweet man! Have you ever drove a classic Stang' with the phat 3.35 1st gear and the .68 overdrive? They really haul, and they have better ratios than older 3 and 4 manual trans. How hard is it to take off a spacer plate and crossmember for the T5 to bring a car back to whatever stock trans it is. I think the TKO 600's are the best 5 speed trans, but for under 300HP, T5 is the way! It will outperform and C4, C6, 3speed, 4speed toploader. Yet, the 6speed manual trans. might smoke it!
Just because classic Mustangs didnt have 5speed trans. in them doesnt mean that it will destroy the car or its performance by installing one. (Quite the contrary actually)

Give the 5 speeds some love!! All automatic only people, this applies to you as well

i agree that the conversion would only help out the car and make it more enjoyable. i like my money and the gas mileage and the thought of breaking something thats hard to get parts for would make my mind up fast hehe and its one more gear you get to shift to! i hope to eventually to have one behind the cleveland.

That's completely false. Just about every drag car on the markey has a Chevy Powerglide which is only 2 gears. And I'd put my money on my C4 against any T5 ot TKO any day of the week and twice on Sunday. More gears does not mean more power. In fact, I've got living proof that a 4-speed Toploader will take a T5. A good buddy of mine has a 65 Fastback with a Boss 302 and a Toploader behind it, and his brother has a 69 Fastback 500HP 408W stroker with a T5 backing it, and guess what, the 65 takes the win.

Don't believe everything you hear or read in a magazine.

Hello. In response to Roy's original post, I was giving him some info on T5's. I don't believe he is going to be dragging his 200cid 6 cyl. anyways. I was talking about the install for street cruising cars. At nearly $2 a gallon, its nice to have overdrive. The information I have mentioned is not based on something I have read, it is based on my own personal experience driving cars with C4's, C6's, 3/4 spd toploader, and T5's, All Mustangs!! No Chevys

A transmission is just a means of transferring power from your engine to your rear wheels via the driveshaft and rear end. It does not make power. However, it does make use of what power you do have and how its transferred. Each transmission, regardless of what it is, has different gear ratios, just like your 8" and 9" rear ends. By using different ratios you won't make any more power, but you will get to use it better. And for street cars, this is the most important thing because your ride will drive smoothly and fly!

I think that a tranny swap would be ok and would not drop the value of the car. The biggest issue that I see is going to get it to work. I have been around Mustangs my entire life and I have yet to see a T5 (first used in 1983 in the Mustang) bolted up to a 200. You will have to come up with a unique clutch set-up, since the stock cluches for a 66 use a unique ring gear and flywheel set up. Another issue is going to be the bellhousing and starter

I was just wondering how hard it would be to make this look good cosmetically as far as how would the manual look on the inside of the car when you got it all in would there be any cutting required or would there be any difficult changes to make this work. Sorry to steal the thread but i am thinkin of doin something similar and i had some questions along those lines.

canadianstang · 04-10-2005

i've never done it or anything just dream about the idea hehe but heres an article on it http://www.fordmuscle.com/archives/2...ap/index.shtml ,if it works, and i think that if you google c4 to t-5 trans swaps you'll get a few good sites. i remember the one guy saying that he was amazed at how clean and fairly straight forward it was in his car like ford had thought about it from the beginning lol. i'm far from tryin anything on my cars i gotta still work out all the kinks from sitting for over 10 years

. so maybe never hehe, and i find it hard to take apart something thats already working when theres so much else that isn't hahaha. good luck
