I was looking at Craigslist earlier and ran across this item. It looks like a good value for someone going this direction. I thought it cam up on a subject recently so I thought I would post.

i thought so to. Much cheaper than converting to an overdrive automatic tranny.

As I understand it, the OD units are all the same, by purchasing the adapter unit for the trans you have this could be installed on any trans.

I wish I had a picture that was a little better. I am having my car painted now and it is just the shell at the moment. He tells me it will be painted and back to me by Dec. 1. I will post some better pics as I progress. Here is one from before full tear down.

It's a good deal on the basic parts, that for sure.
There's lots of re-engineering that goes into
stuffing one (particularly with a C-6) into a '67
or '68 Mustang. My guess is that it would be a
great deal easier on a bigger car.
On the Mustang, You'll be fooling with driveshaft
angles and to get it right with a C-6 will require
other than stock motor mounts at the very least.
Figure on "fun and games" with the trans mount
as well. I got my setup as close as I could with-
out massaging the trans tunnel and then used a
carbon-fiber driveshaft to get rid of the last
of the pretty obnoxious drivetrain harmonics.
And you'll want a GV right-hand drive adapter for
the speedo cable connection to the unit, it's
that tight under there and you'll need it.

Mine is a '68 w. C-6, GV unit, 9".

I'm assuming your not directing that statement at me?

It (GV unit) only makes sense if.....

1) You can get it at a reasonable cost
2) Have a ton of power and want a real OD gear
3) Possess the technical acumen to do the install
yourself and fix drivetrain issues that you WILL
have

#3 means you're basically on your own. They can
do only so much tech support over the phone.
The unit is designed for motorhomes with a lot
more leeway in terms of space under the vehicle.
Putting one in a passenger car, let alone in a
Mustang, does provide some challenges to someone
operating in a Do-It-Yourself manner.
(That's another way of saying it isn't a typical
"bolt-on" job)

I'm assuming by your responses that you have direct experience with the installation and operation of the GV unit. Yes? No?

Was it an upgrade that you would not want to live without?
I would agree that installing one of these behind a C6 would be difficult. Installing one behind a C4 in my 66 was really pretty easy, a little bit of reshaping on the depression of the floor just behind the shift lever hole was all that was required. I also agree with the 90 degree speedo adapter, without it the cable failed very quickly.

Do ya think?
See post 1766285- about 4 or 5 before this one.

Lots of experience with them, their unit and
the installation thereof.
My installation was not easy. It was not fast. It
was not for the beginner "shade tree mechanic."
A C-6 in a 67/68 is tight enough, let alone with
a GV unit adding to the equation.

I was directing that question to you.

By your response perhaps you take a negative view...


Not my stlye

My style is positive...I have been wanting a gear vendor ever since I have read about them.
I was hoping that your answer would be along the line of -now that you have one, you could not imagine not having one-
because it is sooo nice.

I found out from there support that the 65-66 mustang is actually a good candidate with a C4, the tunnel is also accommodating without modification.

Could you tell us what you like most about it.
I am so glad to here a member here has one and am dieing to here of your experience.
I plan to probably use it mostly just for the highway cruising.

I've had it since about 2000. It's not a bad
setup, just in my application it is more of the
proverbial "80 pounds in a 40 pound sack."

I run a C-6 in that particular car because I've
broken 2 C-4's and the costs were getting pretty
outrageous. Most of my issue is borne because
of the size of the C-6. And the overall length
of the C-6, the gearvendors unit and a 9" makes
for about a 2 foot long driveshaft- any problems
with drivetrain angle are magnified as a result.
To make it work right became a very expensive
proposition in my case......

I use mine mainly as an OD unit. GV highly touts
it as giving you "six" speed ability, but the
shifting process is far too cumbersome to make
that practical. Engaging the overdrive gives you
a 660 rpm reduction in engine speed. (My 3.25
rear gear essentially becomes a 2.75 or so when
it's engaged)

This was very good information. I haven't heard much about how tough it is to install a GV in a Mustang. I wonder if they make one for a T-5?

Maybe I should look at their website!

Or, I guess stick with one for a 4 spd toploader since those trans are tough little monkeys.

Thank you for sharing,

Dean T
