C4 transmission

Bigg_Nate · January 28th, 2010, 01:33 AM

OK to start off Hi everyone long time no talk. lol. BUt on topic I have a 2000 v6 mustang automatic it has the 4r70w ( sure yall know) im wanting to put a c4 in it. I know it will bolt up but what other problems will i run into? Driveshaft, speedo gear, input shaft, etc ANy help would be greatly appreciated my tranny is about to go out.

shine1stang · January 28th, 2010, 09:51 AM

first off y they heck would you want to put a c4 in it? I have one and although its good for racing, it totally sucks on the street and long drives.
Anyway to answer more of your questions; your driveshaft will work but you need a c4/t5 slip yoke. The 99+ had the electronic speedo gear so you'll have problems there. The c4 trannys have the mechanical teeth for the speedo gear. Maybe someone on here has done a speedo swap that could help you with that

Bigg_Nate · January 28th, 2010, 03:42 PM

it was just an idea. i need a tranny but dont feel like spending 300 for a 4r70w than the 170 shift kit and a 150 manual valve body and then 500 for a 2000 stall torque converter and than gears and t loc. Im wanting to add a little get up to the sixer its to slow right now and in college trying to find the cheapest route being money is tough plus paying for school. I was just thinking the c4 might make iot a little quicker. Any one know where i can get a used transmission. The cheapest 4r70w i found was 278 with 70,000 miles on it

What is wrong with your trans?

Bigg_Nate · January 28th, 2010, 03:51 PM

slipping going into second, doesnt always lock overdrive in, and the car is pulling horrible weak like i would get outrun by my buddies b16 crx

Bigg_Nate · January 30th, 2010, 04:57 PM

anyone know where i would be able to get one from

Bigg_Nate · January 31st, 2010, 04:46 PM

no the 4r70w

Bigg_Nate · February 1st, 2010, 03:07 PM

and also would the v6 tranny hold up to a 302 if so would the torque convertor or anything like that need to change

shine1stang · February 1st, 2010, 05:46 PM

yes the v6 tranny will hold up to the 302. They only put out a lil more power than you make now. You will need to make sure you use a flexplate for the 302, for the balancing. The converter will bolt right up. The 4r70w is a strong tranny and has proven up to 500whp, with a jmod and new converter. The stock converter starts slipping in the 300hp range.

Bigg_Nate · February 1st, 2010, 10:51 PM

ok good im thinking about getting a 302 bored to a 308 port and polished heads with 3 angle valve job small nitrous cam(dont know what size) i have seen this motor run a 8.50 in a 95 mustang with an automatic with overdrive. How much will the v6 tranny and gearing effect this time? Thanks for all the info guys

shine1stang · February 2nd, 2010, 08:25 AM

u must be saying 8.50 in the 1/8 mile right? 302 blocks have been know to split at 500hp or so. If you wanted to drop in a v8, just get a 351 block and stroke it to 410 cid. Our partner in crime builds 410 strokers that run 9s (in the 1/4) on motor.
gssmotorsports.com, his car is the blue one in the gallery

shine1stang · February 2nd, 2010, 08:28 AM

sorry totally skipped the tranny question. Well if you get a converter that is properly matched to your setup the car will run better. I really dont believe there is any difference in the 4r70ws. Either way you are gonna need like i said above, jmod or aftermarket vb, and converter.

Bigg_Nate · February 2nd, 2010, 02:55 PM

o ok. Cool well i can get this motor for 300 its my cousins and to be exact his time is 8.41 on motor in the 1/8. So as long as i get a valve body and torque converter i should be fine. One more question. What type of converter are you talking about and what type vavle body. Sorry for all the questions i just know how to do it and make the changes and modifications just not sure what would be the best. I will be spraying the car also with about a 125 shot.

shine1stang · February 2nd, 2010, 03:49 PM

is this motor goin in the 2000 mustang? Is the 302 carbed? If not then you have a lot of work ahead of you... Its just not worth the hassle!!!!! At all!!! Im not sure if the 302 will drop right in your kmember. I know when they changed from the 302 to the 281(4.6) platform they changed k members too.
For the tranny crap contact bc-automotive, Darrin knows his stuff

JTs03v6 · February 2nd, 2010, 07:15 PM

A 302 is going to be a waste of time. Go with 4.6pi or dohc. If your impressed with a 302...you will damn sure be impressed with a boosted or sprayed 6...4.2 with a cam would be the sweet spot imo....and a whole hell of alot easier to swap in.

Bigg_Nate · February 3rd, 2010, 12:12 AM

Scott2001GT · February 3rd, 2010, 12:15 AM

I wouldn't street a C4...rebuild yours if needed get a shift kit, stall, and transcooler and your good man.

tooldrmr2009 · February 4th, 2010, 05:05 AM

hey if your interested...just a thought. i have a 2001 v6 auto tranny laying around currently in the garage. It was pulled from the 01 with about 75k on it and shifts beautifully, just needs a new torque converter anyway but its all there. I picked it up from a combo with a motor, trans ect from a guy that did a 4.6 swap in his 01 v6. if your interested shoot me a PM ill let it go for really anything its no use for me.
