First drive with Gear Vendors overdrive in M1010

[@musclebone7875]

I just took my '68 impala out today for a cruise with my gear vendors overdrive! Love it!

[@crazyhorse3275]

Brian how does it works? Do you just put that on drive and set the gearvendor on automatic and it shift all the 6 gears automatically if you have a th400. I’m curious I have a 77 el Camino column shifter that is my concern. Thanks.

[@musclebone7875]

@@crazyhorse3275 i just leave mines in automode. The computer will shift it. Makes my th400 feel like a modern transmission.

Hello, currently trying to install a used one on an m1008 but bought it with cut wires and cant figure out how to wire the 4x4 lockout, you have diagrams or able to email me a pic of the control box side and the other end?

Chevy Mike... I own a 1998 RV with the L29 454 and 4L8E... It's a 29 footer at 16,000 gvwr.. with all my mpg mods I achieve 11.3-12.8 mpg.. my trans already has an OD.. with going double OD by using the gear vendor improve my mpg? I know it will improve the driveability by cutting gears in the auto function Please a video on how to service the gear vendor... Liked and subbed

I have a gear vendor in my 1980 el camino I can get it to shift manually but it wont atuo split shift does anyone here know what it could be?

[@darrininverarity4297]

You should make a in-depth video of the install.👍

I have been debating on getting a gear vender for my c6 f250 or buying a 4 speed overdrive transmission, these gas prices are killing me so I think I am going to get the overdrive just for the simplest install

[@miketlane]

im in the same debate, gear venders or trans swap.

[@bigtender7655]

I got a gear venders but it won't show over drive the green light it did one night but now I can't get it into over drive maybe I need to take it on the road when I get new tires and tips on how to get it going I got the floor switch and everything

[@chevymike1968]

Are you driving a diesel rig with glow plugs? I know when those cycle when starting, they cause low voltage issues and will freak the brain out. I actually wired the input power to the brain on a switch that I don't turn on until after the glow plugs have completed cycling. Other thing to check is to make sure your speed sensor is connected as it must see a specific speed to engage/disengage automatically.

I have a 1986 cucv as well and I would love to get the gauge setup you have. As well as a gear vendor. I have an option to buy a used vender. I’m just not sure how well they work. Could you give me any pointers where to shop.

[@chevymike1968]

Thanks. The individual gauges were custom built by Speedhut Gauges, to my design. I then custom modified the factory bezel to fit them. As for a used Gear Vendor OD, you need to find out what series it is. I think early ones were J series and later ones were P series. Don't waste your money on an early one as there are no parts available for them and GV doesn't support them. For it to work automatically, you must have all of the wiring and control box for it. Check out Gear Vendors website for more info.

What’s that cap underneath the switch

[@chevymike1968]

That is the military diagnostic port that all CUCV vehicles have. Mine is a M1010 ambulance.

I'm looking into this for my M1010 as well. Have you improved mpg? I get about 13mpg.

[@chevymike1968]

Sadly, I have only put about 150 miles on it since installing.

[@RBLUS_TY]

So exactly how does the autodrive work? Does the gear vendors shift on its own in that mode?

[@chevymike1968]

There is a control box and a speed sensor. In Auto mode, around 40 mph the overdrive will engage automatically. When you slow to below 20 mph, it will disengage. You can manually disengage in auto mode with the floor switch. In manual mode, the overdrive will not engage unless you manually select with the floor switch, as long as you are above 20 mph. Hope that helps.

@@chevymike1968 You helped a lot, dude. Thanks! I was considering a Gear Vendors for my E4OD.
