Questions:

Steve
(314) 409-6731

The wiring harness is 03 Cobra specific. I would double check
the 3650 harness. I am almost sure they are very close in
design though. Enjoy.

If you wanted an auto why did you buy a 5 spd???

He he...check my sig. :D

More info on the Fox body rear.
I didn't think they were a direct swap for the 96+?
I guess your ABS is long gone?

Um, ok, I dont' see the answer, am I blind? :D

The question still stands for me. even with a 10 sec. car, if you are going with an auto, it wuldn't be stock anywho....:confused:

He put an automatic in his cobra, which only come in manual.

.


Since when?

I will be happy to admit if I am wrong, but I believe since 1993...

I believe SVT has never produced an Automatic Cobra. I can't be positive for years 94/95, but I am pretty sure. I am however, prositive that they have not produced one from 96 and up. No auto 4.6 4V Cobra;)

Lentech is not a stock automatic!

So steve?
 

So steve how much did it cost you total to turn ur stick into an auto? How do you like it, what kinda tranny u got in it, let me know

Funny this came up. I was wondering how hard it would be to do this to a 97 cobra convertible. Total $? What about labor?

Switch for overdrive to replace coin holder? The OD switch should be on the side of the shift handle.

It bolts up like one. All the fastening points and sensors are in the factory stock location.

I used a fox rear to tuck the tires in. 28x13.5x15 Hoosiers in the back. They do work on 96+ cars. I have the rings pressed on the axles with the sensors in place. ABS works fine.

Honestly though, if I had to do it all over, I would not bother with the ABS stuff. It's a foo foo feature that just costs extra money to make work. And the **** ring gets in the way if a stud gets spinned in the axle.

Add all of the parts above, along with:

-Lentech Strip Terminator 4R70W ($2595)
-9.5" 3200 non-locking converter ($595)
-35 spline input shaft and stage 2 drum ($399)
-Shipping ($175)

I sold the T-56 for about $2000, and some other goodies that were associated with the manual tranny. That helped with the cost.

Labor is a good weekend. Like any "larger than bolt on" job, the most difficult part is having all the right parts on hand, and having someone around to go on a part run.

Getting all the parts on hand is key, that shortens labor. That is why I created this write-up and posted this up. To save time and aggrevation for anyone who chooses to do this. :COOL:

no autos in cobras? really......Can you tell I dont' know THAT much about them...duh.


Now why did they offer the mach with an auto, but not a cobra? I could have sworn I have seen listings on dealers websites with cobras having an auto......ok that is it I am going crazy......


It is especially wierd because there is a girl that has an 04 cobra, brand new no plates, around here and I could have sworn it was an auto.....tall tale signs....smooth shift, no delay between gears, breaking until light turns green.....man am I lost....no offense to the women that come here, but this girl looks like she can barely drive an SUV....you'd have to see her.

I see now. My nephew did the same with his 03 snake no more 6spd or IRS although he used a MACH rear and Stock Tranny

The Mach 1 is just an upgrade package for the GT. Most of the paperwork I have from Ford that came with the car has it listed as a Mustang GT with Mach 1 package.

There are a couple of women that I know who can shift smoother than what I do normally. So the girl could know how to handle a stick, or she/her parents have to much money and had it converted for her to ba able to drive.

I'm pretty sure I have seen a 4V auto before. Last year would have been 98.

Not in a Mustang.

There is no such thing as a Factory auto cobra period.
No arguments, no speeches. They never made one.
I did do some minor assisting in Steve's deal though.

So there are a handful of conversions. When you have a car like Steve's..you couldn't shift fast enough...:)

Maybe you guys are right. I could have sworn I saw a 97 or 98 black conv't with an auto.

No maybe's about it. There has never been an auto tranny offered by Ford in the Cobra. If you saw one in a 97 or 98 it was either a conversion or a Fauxbra.

:agree:

jc

No Cobras had autos, but there were so many people that put the snakes on their gt's to make tham look like a Cobra.

I had a 96 Cobra coupe and a 97 Cobra convertible and everyone always asked if they were sticks or autos. I always had to explain that there were no auto cobras ever.

The auto option in the Mach is very unique because of this, that's kinda why I got one.

I am still at a loss on why Ford decided to give you guys a cast crank and 6-bolt flexplate. :confused: Doesn't Ford make an 8-bolt flexplate for the F-150s?

a long weekend steve?! tell the truth, I bet we had a good 3 or 4 days in it, but we were also runnign around trying to find parts to maek it work, but yes, that auto shifts fast!!!!! and when u plug in the main wiring harness, do it before the tranny is bolted up or get so9meone with small forearms to squeeze it up there, I did it, and its not fun!

Why, is he going faster than the Pro-Stockers? I remember Grumpy Jenkins going in the 9's with the same 4 speed tranny I had in my Chevelle at the time.

Sorry, each to his own, but why would you want to swap to an auto in a Mach (Machs are what this forum is about, right?)? Wouldn't you just buy one that way?

very nice write up on the parts needed and what not to make it work :THUMBSUP:

You most likely have seen Auto Cobra's listed online. There was, maybe still is, a problem with ebay and some other automotive for sale sites that when you would put in the VIN of the Cobra, it would automatically list it in the template description as an AUTO.
There are a LOT of dealers out there too who list Cobra's with auto's, because they are dumb and lazy and don't go out and check/or accidentally put it in there. These are usually the dealers who want WAY to much for the car as well. They know nothing about them, besides that fact that they are expensive!

The thread is about HOW TO put an auto in a 4V. Not SHOULD I put an auto in a 4V. :D

Why would a five speed Mach1 owner want to switch to an auto? What if an owner builds a D1 procharged car and wants to leave the line with boost? What if an owner builds a 700 rwhp setup and is tired of destroying rear end parts, input shafts, and clutches?

Simply put, switching from a manual to an auto is not just for Cobras. :THUMBSUP:

Auto?? In a cobra????.................Why???????

For the guys asking "why" even after you have been told that the built auto is stronger and actually helps the car to build boost at launch to make it FASTER and doesn't need new clutches every month you need to first own a car that makes 600+ horsepower then act like you know what you are talking about. I went with an automatic trans (c4) in my 408 coupe for similiar reasons as above. :wall:

Thanks for the good Tech info on the swap 03Steve!! :yeh:

The auto is the way to go when you are making over 500 HP, want to leave consistently (trans brake), shift faster and never miss a gear.

My friend's brother in law's cousin said had an 04 cobra with auto...You guys don't know what your talking about....j/k :tongue:

Re: How to change your 5 speed to an automatic
 

Thanks 03Steve! I asked this basic question MONTHS ago with no replies. I hurt my knee in a motorcycle accident and have had a couple of surgeries on it. It bothers my knee to drive around with my 5 spd a couple of hours but I am attached to the car and want to keep it rather than sell it. Not to mention I wouldn't want to give up the forged crank in the 5spd models. Also that was a good idea to put the fox live axle in. I already got axles for the Mach, but I didn't like the fact that backspacing is as far as I could get it but the tire lacks that tucked in and fat look. No rubbing, but it looks wrong. Maybe I could run the 325's instead of the 275's. Actually, if the new 5 spd auto is tough enough, I'd like to look into that. If you hear anything on that swap please pass it on to this thread. :yeh:

enjoy... saving money by doing it yourself and not having lentech do it for you... hehehe

Re: How to change your 5 speed to an automatic
 

Hey RotaryMagic! Thanks for that link. There's some great information on that site and I picked up a few good ideas!

Re: How to change your 5 speed to an automatic
 

Jerry's site. He HATES Lentech. :)

Re: How to change your 5 speed to an automatic
 

I guess it's too early to say whether the new 5r55s 5 spd auto can be made to work. Install shouldn't be much more to it, but I was thinking the management of the trans.....?

Re: How to change your 5 speed to an automatic
 

just beautiful 03steve :worship: :eyebrows: you have anymore pictures?

Re: How to change your 5 speed to an automatic
 

i love that sonic blue
:D :gears:

Re: How to change your 5 speed to an automatic
 

Theres one thing missing no one has talked about the computer that runs the auto. Power train module , ecu or ecm whatever it is called I thought it contols both engine and trans on a automatic car.

Re: How to change your 5 speed to an automatic
 

I asked earlier but no respose. I'm a newb at this trans mgmt. thing so can anyone tell me how it works? Do you change out the computer? If so how can it manage a Cobra engine that didn't come with auto. Info please. I would consider putting the 5r55s in the mach if I could get it to work.

Re: How to change your 5 speed to an automatic
 

Keep your stock manual computer. I am using my cobra's original computer too. The transmission is shifted manually by me. With the manual valvebody, I click through the gears on my own and hit the switch where the coin holder goes for overdrive. It is a stock foglight switch out of a 96GT.

Or, do what my buddy from Delaware has done with his 03 cobra. Put an auto Mach 1 computer in your stick shifted car. :yeh:

Re: How to change your 5 speed to an automatic
 

Cool, thanks for the info. :yeh:

Re: How to change your 5 speed to an automatic
 

The three actual 1994 Cobras used as pace cars for the Indy 500 had automatic transmissions. Those are the only Cobras ever produced that weren't sticks. This is a safety requirement for the race. Just a fun fact.
