Gear Vendors OD

[Comin' in Hot]

I am currently in the process of gathering info for installation of a Gear Vendors overdrive into my DBP. My plan is to run 4.56 gears and be able to still drive it on the highway. Gear Vendors tells me it will be like having 3.55s with the double OD engaged.

I can't find any info of an install to a 4R70W. GV says they have done a few marauders, anyone here have one installed?

[lji372]

nope, but
could they take my 3.55's and get me 30mpg:banana:
wouldn't that be nice......

[MOTOWN]

Definitely a mod in the future for me, turns our 4 speed auto into an 8 speed automatic!

[Comin' in Hot]

I don't mind being the pioneer here, but getting info from GV is ridiculously painful

[MOTOWN]

YouTube should have some installs with this combo, prolly in a Mustang though

[Mike M]

Big bucks!

[MOTOWN]

About $2,250 for the unit

[babbage]

3.55's become 2.76 RAR in OD mode, might be able to hit 30...

[Comin' in Hot]

Big bucks!

I'm figuring about 4500 until I get the rear built(already have the parts), new driveshaft and the miscellaneous stuff I'm not thinking of. I know it's not cheap, or the route most here would go, but what isn't expensive for our cars?

I read that, but The trans was changed to a TH400.

I finally recieved an email from GV, they asked me to call them. Hopefully I'll have good news tomorrow.

I am in SoCal today. I drove to El Cajon to Gear Vendors. I spent about an hour talking to Nick, my tech support contact and grandson of the founder. He gave me a shop tour, showed me projects they were working on, and at the end of the tour I pulled the trigger.

We both agreed a manual activation with a simple push button is the way to go. My next move is to take off my tail housing to count the teeth on the speedo sensor gear, he mentioned that 03s and 04s are different. Once I count the teeth I should have the unit about two weeks.

[FastMerc]

I often wonderd about this gadjet but never knew anyone that used one. So I may be interested somtime...

My main reason for using it is that I want to run 4.56 gears, but also want to drive it on the highway. With the OD engaged the engine toms will be like I have 3.55s

Sweet! this is one of my 2014 mods! goodluck:banana2:

Minor setback today, I went to count the teeth for the VSS on the output shaft and it appears our marauders don't use them. From what I could find, ford stopped using them in '99. I guess I'll just have to wait until Monday to see what GV had to say.

VSS was last used in 2002, in 2003+ its all in the PCM.

[lifespeed]

You'll spin the driveshaft real fast with 4.56 gears.

[justbob]

Completely irrelevant but my research came up with the magic number of 6 pulses for the 4r70 and 12 for the Tremec I installed. Sure enough, my speedo was exactly double and was easily recalibrated on the dyno.

Also in 6th gear which is a 0.50 ratio my RPM's are dead on 2,050 @ 80 with 4.30's.

Not sure if any of this will help, but maybe for a comparison.

Awesome Derrek! So did you figure out your Speedo? Or are you just going to calibrate it on the dyno? Don't be fooled into purchasing a module. If its anything at all like I went through, then it is just a simple adjustment through the Xcal on the dyno.

It's actually 14 speeds (first gear TC is always locked) , if you consider the TC lock and unlock in every gear except first.

Can't wait to see this! I want this mod, then I can get 4.30's... Also because the factory driveshaft will have to be shortened, there will be less of an issue with drive line harmonics at high speed.

Maybe. Maybe worse. It does alter the pinion angle, but only slightly.
Does it have a fixed flange or slip joint?

Your (steel?) shaft is shorter now, do you get any vibrations in 3rd or 4th at 5,000ish? GV uses a slip yoke. I noticed that Denny's Driveshaft has yokes for the GV setups.

[Comin' in Hot]

The yoke is a slip joint, and if anything I think I'm going to have to space the trans/GV up due to how low my car is.

I'm working on my revised intercooler plumbing right now, hopefully ill start the GV install this weekend.

Any horsepower limits on the unit? Not this engine but maybe the next.

[License2Bill]

I'm intrigued. If I understand correctly, this piece basically lowers the final drive ratio when engaged allowing for highway speeds without over-revving the engine, in turn, increasing gas mileage?

I currently have a dynotech drive shaft, but I will be ordering a new carbon fiber drive shaft, plus it's going to be about a foot shorter.

I haven't even started this yet because I'm trying to get my heat exchanger back together, it has officially become the project from hell. The only good news is that I should have it finished tomorrow.

I was going to start the install tonight, but I looked closer at the adapter and I was not happy with it, I emailed pictures to GV then called them to follow up. They checked the 4 they had on the shelf and they looked the same. GV uses Advanced Adapters as their supplier for certain applications and GV agreed it's not up to their standards and is working to rectify the problem. So now I wait.

Who does that and calls himself a machinist, who checks it in and ships it out for that matter. If nothing else they're consistent :dunno:

[Windsor58]

That is bad. Let us know how they treat you once it is all over. Sounds like they are going to do the right thing, at least.
If you know, how much weight will the OD unit add to the car, altogether?

Nothing a little duct tape won't fix.

the shipping weight of the box it came in was 69.9 pounds, so I would say about 66 (+-2lbs.)

It's not that I can't fix it, it's the fact that I shouldn't have to fix it for the cash I shelled out.

I am ordering mine this week for my Pro Street Camaro.

[Comin' in Hot]

Update: I talked to GV, I packed it up this morning and I'm sending it back tomorrow. GV insists the adapter is structurally fine, but I refuse to put it on my car like it is, I have corrected too many half assed things so far. I refuse install it based on aesthetic reasons. I refuse to pay more to add material to it and remachine it.

What other half assed things have you had to correct from gear vendors besides this piece? A while ago I called them and told them I wanted one but was wating to see how they took care of you and had seen the pictures etc..

I believe he was talking about DR and what he did to the car, not GV.

[Comin' in Hot]

I was referring to DR.... GV has been great with the exception of the adapter, I understand their view of it, to me it's not no acceptable. I want everything I add to this car to be perfect, and I believe if my last name was Foose it would have never ended up at my door like it did. I shipped it out today, I'm now out another $120.00 for shipping. I'm also rethinking my entire build based in not having this unit.

Next the trans will be pulled to have the correct output shaftand tail housing installed.

They now say I will have mine in 1 more week. They are waiting for 1 component to come in.

Kinda weird as my application is pretty straight forward. Oh well...we shall see.

It will make my 4:56 act like 3:73 when I hit the button. I will be able to drive the car on the highway without killing my engine.

Do they actually think we believe GV would put that on display as their product at SEMA?:confused:

Actually 4.56 becomes 3.55's when you hit the switch. This was always my attraction to the GV setup.

[Comin' in Hot]

Gear Vendors is a really small family owned company, most of their employees have been there for years, so it wasn't just some salesman.

They technically do not make a Marauder kit. No one make an adapter for the 4R70W. They get a 4x4 adapter from Advance Adapters and machine it down.

I don't think it was going to break, but my main issue was that the top and bottom holes should have never been drilled. They are not usable and they are both through structural ribs, if they wouldn't have been drilled I would have kept it and lived with the thin walls of the bolt holes. Its a machined fit from the adapter to the OD unit, so with the 4 bolts it wouldn't have gone anywhere. It just looked horrible.

[chief455]

I have experience with Gear Vendors typical applications = GM car with TH400

High quality, does not break, good support. I've seen 800+rwhp run through without issue. If it comes down to a custom adapter to a trans not past prototype stage, not fair to criticise, really.
Aftermarket typically sucks in every way, in my 35 years of building experience.
Expect every part you buy to need fabrication, modification or something. If it works first time - woo-hoo!!

so does the normal trans shift first then the GVOD??

Or is that what the split shift is back and forth between the 2??

these are an over and under drive.
In manual mode, you can be in 1st gear on your tranny, shift into OD on the gear vender, then into 2nd gear on your tranny, into OD on the vendor etc. It ain't easy split shifting a fast car, nor needed. In auto mode, it will go into OD after your tranny has finished shifting and reaching a preset mph. go to the website and read up.
Sweet set up.
