Anyone using one and if so what do you think of it?

HEY BLOWN: Funny you should mention that, I was on their website yesterday reading some of the magazine test reports.
WWWgearvendors.com It looks like pricing is about three grand and it is designed more for trucks and RV's that cannot find right gear on long grade. Interesting product but my reaction was that it was not enough bang for the buck for just street driving DAVE

I've been eyeing one ever since I read about them in HOTROD. I think they'd work awesome on the street, and on the highway too. I'm wanting to run 3.73's in my car, but would also like to do some interstate driving with it as well, and with the overdrive unit it makes it seem like it's actually 2.91's in the rear. If you go to the website, it also talks about people that race with them, giving them twice as many gears to run through, obviously keeping your engine in the optimum powerange. I don't know, but I want one!

i have been looking into the od units also. expensive!!! you might as well but a new richmond 6-speed! or you could try to find a doug nash 5-speed from mid eighties vettes. they are alos known as a 4+3 transmission. they have an electric od. you can turn on the od in 2nd, 3rd, and 4th. hence 4+3. this tranny gives you the same effect as the gear vendor unit and is way cheaper. you could pay for the tranny, a rebuild and install for less than those gear vendors. just my .02c

I like the idea of the manual trans as mentioned but would it be nearly as strong. They make these for powerglides as well.

how strong is strong? 500hp, 600hp? richmond 6-spd handle lots of torque and hp. all depends what you want. if you want a cruiser than i personally would go with the 6-spd. why spend the same for a unit that hooks to you old tranny when you could buy a brand new tranny with the same amount of money? maybe its just me but gear vendors has INSANE prices.

that second brand unit looks better(in terms of price). handle 500 ft/lbs torque. not bad.

Im starting to like the US gear version. Im hoping it may get cheaper. I think this one is a little more popular and is getting cheaper. If money allows I may decide on getting this unit. I like the idea of a bulletproof tranny. I think this unit is rated very high. If you read it says "500 lbs + torque from dead stop with overdrive" I believe this unit is capable of alot of abuse. And a 2 speed or 3 speed can be built close to bullet proof.

Taken from very first page.

"Applications Available for GM 2 Speed, T350, T400 (with 4.25" tail housing), 700R4, Ford C4, C6"

I think its strictly for auto

Well thanks for the info.
I have never heard of the other unit but I will be doing some checking into it.

As far as the manual tranny idea I have already thought about it and it would not really be for me.
I have already got WAY too much money in the tranny I have including a $900.00 ati tree master converter.
It works great and very consistant but I would like to get on the interstate and at least run near the other cars that are passing me like Im at a stand still

This one looks like a no brainer. They even have an article with them installing it in a 68 camaro. It looked like a bit of a pain.

I found this link.

"The GEAR VENDORS in combination with the Powerglide is an affordable, reliable, and very efficient package. This is a superior alternative for most cars looking to go to a 3-speed. The GEAR VENDORS .78 to 1 ratio allows you to go to a numerically higher rear gear to improve your 60ft. times and get it all back with the overdrive. The reciprocal of our ratio is 1.28 so a car that currently runs a 4.56 rear could go to a 5.84 without loss of top end. You will have these improvements with reduced cost, greater reliability, and lower parasitic losses when compared to conventional 3-speeds. The overdrive is switched on with 12-volts and so is easily adapted to steering wheel buttons or automated through rpm switches. The product is ideally suited in stock form for cars with 1200hp or less and in this case is virtually indestructible, literally running for seasons of use without maintenance other than fluid. Cars with 1200+ horsepower can be accommodated but you should call the factory so hydraulic issues dealing with clutch ramp timing can be properly adjusted for your application."

Hey guys/gals, I am new here I stumbled accross the Gear Vendor post while doing a search on the web.

I personally have a Gear Vendor in my 1970 Camaro. The units are very well built and STRONG. They can switch into and out of overdrive automatically or manually. When I have mine in manual I shift with a foot switch. The price is high, but what other overdrive tranny can handle 1200HP? I have broken two th350's and haven't had a single problem with the Gear Vendor. I am in the process of switching to a th400 and I plan on keeping the Gear Vendor. It allows me to run 4.10's on the highway and cruise at 80mph. If I was starting from scratch with no tranny I would probably consider a 200 4R, 700r4 don't take abuse so well. Look at the price of a well built 200 4r and a performance convertor and it is well over the price of a Gear Vendor. So if you already have a solid trans and convertor a Gear Vendor is not a bad option (price is the only drawback). You can also shift into and out of OD in any gear which turns a 3 speed auto into a 6 speed auto. Comes in handy. I just thought I would add some real world experience to the post. Looks like a neat site I will have to visit often.
