Hey Corky/BB people with newer Trans. in our old Stangs

What are you doing for Speedometers?  What's my options to get the old speedo to work?

Re: Hey Corky/BB people with newer Trans. in our old Stangs

Funny you bring that up.  I was planning on getting the correct tooth gear for my cable this week.  I was under the impression that you can get a gear that fits right into the T5?

Re: Hey Corky/BB people with newer Trans. in our old Stangs

I used an Autometer speedo and a GPS sending unit. LOVE IT....

Does your 4r70 have the speed sensor on it like an AOD has?
 The stock AOD sensor will accept a dedicated cable to drive a stock speedo  unit and gears are available to get the correct read out.
 If down the line you opt to go all aftermarket gauges that same sensor will drive most available speedometers..

Re: Hey Corky/BB people with newer Trans. in our old Stangs

Mike...what Rudi says.  If the Mk8 did not have a speedo cable driven from the VSS adaptor you might be able to use the VSS and adaptor from an AOD or other 4R70W application.  Otherwise you're kinda stuck going to an electronic or GPS speedo.

Re: Hey Corky/BB people with newer Trans. in our old Stangs

4R70W has a cable attachment point in the tailshaft extention, so your regular speedometer can be used. Which is the system I use in the 73 Vert. Cable easily mounts in an VSS location.
In Miss May has an Autometer electric speedo with sender, mounted on the Trans main body.
Either method can be used. The 2+2 formerly used a cable. Note-4R70W has two locations, unlike an AOD, one mechanical/VSS(in tailshaft housing) one to drive an electric sender. There are some 4R70W tailshaft housings without the boss drilled to accept a VSS. Just use an AOD short tailshaft housing which fits the stronger T-5 yoke anyway.

Re: Hey Corky/BB people with newer Trans. in our old Stangs

Thanks for replies

I guess I'm going to have to look at my trans a little closer, cuz I don't remember seeing a place for a mechanical cable. I remember a sensor going into the tailshaft.  Are you guys saying that I take that out and a cable will go into that hole?  

Mach1  do you have any pics of your GPS set up?  Do you just replace your speedo with their replacement?  Guess I'm going to have to do some searching on Autometer speedos.

Re: Hey Corky/BB people with newer Trans. in our old Stangs

The 4R70 transmissions use a DS yoke with a larger barrel diameter than the C4-AOD's. The 4R70 yoke also has a large diameter harmonic ballancer, which can be problematic in the trans tunnel. I swap put the 4R70 tailshaft housing for a short AOD version. Which allows me to use a T-5 yoke which is both stronger internally and has no harmonic ballancer ring to interfere beneath the car. The speedo cable can be mounted in the AOD tailshaft housing port or an electronic sender.
The 4R70's alternate sped sender is wired into the 4R70 harness.

Mike;

The AOD VSS goes into the speedo hole and has the driven gear that engages the gear on the tail shaft.  The VSS has a connector for the connection to the PCM and also has a straight-out connection for the speedo cable.  A special cable is necessary to connect to the VSS on one end and the stock Mustang speedo on the other.  Ron Morris and others sell that cable.  Or... you can use an electronic speedo and tap the Pos and Neg VSS leads for speedo input.

The GPS speedos have a separate sender that mounts somewhere in the car and sends GPS speed data to the speedo.  I think some also have the ability to take the VSS signals.

Re: Hey Corky/BB people with newer Trans. in our old Stangs

I would prefer to use the original speedo if I can.  I'll have to get under there and look at the tailshaft again, maybe take some pics if possible.   I don't have a lift, so I'm not too crazy about crawling under and laying on the concrete. Definitely getting too old for that crap.

Is this what you're sayin I can remove and get a connector/adaptor from Morris so I can put a manual cable into it?

Re: Hey Corky/BB people with newer Trans. in our old Stangs

I just did this. I used the stock foxbody cable.

Take the plastic clip off the speedo end. Cut some of the metal sleeve off with cut off wheel.

Then cut a slit lengthwise with cut off wheel. Slide this onto back of stock speedo and use hose clamp to hold.

I wasn't going to spend 100 bucks on the Ron Morris cable.

I figured out how much speedo was off and got correct gear.

Re: Hey Corky/BB people with newer Trans. in our old Stangs

I have used a Cable X box, made by Abbott industries, to convert from an electronic T56 to an old mechanical speedo in my son's sbc powered 83 S10 pickup.  The converter box has dip switches with infinite settings to get the speedo to read accurate.  We had several gear ratios in the narrowed 8.8 and multiple tire sizes on that thing, and we always could get the speedo accurate.  A little pricey, but really did the job.

Yes, that's the  VSS with open end for a Fox type speedo cable.  The cable sticks in the open end and is held in place with  a spring clip.  I personally like FFR3247's approach.  DIY and save a bunch of bux.

You can pull it from the trans and change the driven gear just like any other ford speedo drive to match up with your axle gears.

Sorry I don't have a pic. But BB is correct, the GPS unit wires up to the AutoMeter Electronic Speedo and I have my GPS unit on the front pice of metal that holds the headliner in at the windshield. It has a magnetic back. The cable is long enough to reach to the trunk if needed. But, if you wanna use your stock speedo, listen to these guys...

I think that's the cable for a T5.  You need the cable for the Auto which will connect to the VSS.  As for the speedo end...follow FFR's instructions.


Here's a Rock Auto link for the right cable.  The first cable listed is the one you want.  These are for the 89 Linc Towncar but are the same as the Auto Fox.  Gotta have that plain end on the trans end of the cable.

Re: Hey Corky/BB people with newer Trans. in our old Stangs

You folks are making this too hard.
Unless your using the VSS for Cruise control or speedometer sender, dispose of the VSS. Just use a stock cable for your car as it will have the propper fitting for the speedometer connection, and plugs into the 4R70 trans just fine. I do reccommend using a manual trans cable in the 65-66's as its longer than the automatic version, fits better.
The 4R70W uses an internal speed sensor, VSS is superseeded and add nothing to the AODE/4R70W trans.
Thats why some 4R70's don't even have the VSS boss drilled.

Re: Hey Corky/BB people with newer Trans. in our old Stangs

Thanks BB, I see what you're talking about, I guess I'll be able to get the clip that holds it in also. I'll probably go to Oreilly's and get one there.  When I searched for the cable they never asked what tranny I had.


Tubo -  Welcome to my world, take something easy and make it hard.  That's par for the course for me.  I took a 10 minute job today and turned it into a half day project.  I was going to put the heater controls back in and then decided they needed to be completely taken apart and cleaned(old grease removed, each lever taken out and cleaned and greased and each cable lubed)  Probably won't work any better than it did.

I'll check my wiring diagrams, I do plan on having Cruise and my CPU controls my tranny, so I'll see exactly where the VSS wires go.  I'm thinking I will probably need a speedo cable and the VSS. butt(TS) I'll check into it somemore.

One more question if anyone is still around and not bored to death.  Since I've replaced most of my sheetmetal, I'm not sure where the speedo went thru the floorboard. Can anyone get me colse to where I should pass it thru?

Re: Hey Corky/BB people with newer Trans. in our old Stangs

Tubo I know your very knowledgeable but I had a issue with my car that hooking up the vss corrected.  I'm not sure if the actual vss fixed it or having the wiring plugged into the main harness fixed it.

When I started my car my idle would skyrocket to @2200 for a second or two them return to almost normal and then stall. It did this everytime no matter the temp. I installed the vss and hooked up the harness and guess what no high idle and no stall. I run a AOD though not a T5.

I have been a foxbody mustang for 20 years and I probably know my way around them better than anyone. I always thought the vss only served as a function for cruise and if it's a manual car, not to stall when u dump the clutch for a stop.

The cable posted was for a non cruise car. I used the one listed with cruise.

Finally getting around to working out all the bugs after my FI conversion. I absolutely love it. More of a pleasure to drive FI. Now to move on to suspension.  I'm tired of sawing on the wheel while driving. It's almost work to keep it on the road. The frontend is all new with stock replacement parts. Alignment is right but just feels like a old car. Lol

Re: Hey Corky/BB people with newer Trans. in our old Stangs

I just started working with my T5/speedo this week. The stock 4 speed cable gear won't even come close to fitting in the mechanical receiver on the T5.  Do I need to change the gear in the T5 or the drive gear on the cable?  I have all the tire size, rear end ratio data but I wasn't sure which one to get!  Thanks.

The 4-speed gear (the driven gear on the end of the cable) is cut in a different direction. You need to install one for a 3-speed, c4, T5... they're all the same.  4-speed is the odd man out.

Ok, thanks.  That's what I was hoping to hear.  The cable length and routing is fine, the gear was the only issue.  I'll pick up a cable side gear this week.
