Maybe I missed it but what supports the unit other than the crossmember?
The GV unit is bolted straight to the GV tailshaft housing. That's it. Apparently it's strong enough. I haven't heard of anyone breaking one yet.

When I put mine in my Challenger, I slid the new yoke in till it bottomed out. Then slid it back out 5/8 of an inch, and measured from center to center on the u joint holes of both yokes. Took that measurement to the driveshaft shop to get the new driveshaft made. The electronic box seems to be the weak link of the system. Check with the GV tech dude to see if yours will live behind that kick panel. Might build too much heat.
I think that's one of the suggested places. I'll double check. I guess I should drive it a while and check the control box for heat dissipation. The measurement scheme I used would have worked, it was the shop that messed it up by cutting off 13" versus the 14" I asked them to do.... They were cool about it this afternoon when I dropped it off..

After I had a control box fail, I ran a spare wire from the foot switch down to the solenoid on the unit. I crimped an end on it, and then just taped it up and left it loose. Did the same at the foot switch end, and also ran a spare to the fuse block to supply 12V to the foot switch. All the solenoid needs is 12V to operate, so I can still get the OD to engage if the box ever takes a dump again. The split shifting was fun for the first 5 minutes, but I just use mine for OD now! Good luck, and you did a super nice job on the install.

Those GVs are bullet proof , had one on the 68 charger , stripped the planetries out before the box got hurt , 4400lb charger constantly put through it's paces @ the track , only issues i had was a control module go bad , GVs sent me one out within a couple days , great aftersales service.................nice work there MickRR.
I wouldn't call them bulletproof , I know a guy that blew up at least one behind a 12v Cummins diesel that was putting over 400 HP to the ground through a 5 speed manual trans towing 29k lb. horse trailers, but most gas engines aren't making the kind of torque a Cummins makes.

Memories of installing mine...I had the same problem in the tunnel with the fitment of the OD unit. Still though, I hate working on transmissions and rear axles. The instructions were simple, easy to read. Took me 6 hours to install on a Saturday plus the waiting of a business day following for the driveshaft work.
Only problem I have is that my H-Pipe sits right on the GV unit where the finned part of the housing is. My exhaust melted the gasket. I still haven't gotten around to relocating the crossover. I have bought 2 spare gaskets just in case.
Only think I can't figure out is the split shifting. 1st (Gear 1), switch (Gear 1.5).....switch/2nd (Gear 2), switch (Gear 3).....switch/3rd (Gear 3.5 / OD)....switch
I can't get the sync right...but I don't drag race it enough to utilize that option, I just hit the button and go to OD....Final driving speed is 80mph @2100 rpm with 3.55s and 28" rear overall tire.
Great job on the documentation. I had documented mine but upon carrying my SD card from my camera to the computer....fell in a tub of tranny fluid at the shop I did it in....toasted

Well , i'm talking about a 4400lb B body , 605" running nitrous , circa 950hp , maybe not a cummins.

Since blowing my overdrive up I've done a fair bit of reading about this style of overdrive and there's a few things you should bear in mind. First of all a 4 speed is going to be a lot harder on the overdrive because there's no torque converter to soften the blow when the cone clutch engages. When driving around town I tend to dip the clutch just after I hit the switch because at low speed/part throttle it bangs in even harder. With the overdrive switched out, the drive is taken up by a one way roller clutch when accelerating or cruising so it's not going to slip. In reverse or on the overrun, the one way roller clutch does nothing and drive is through the cone clutch which is held against the annulus with low fluid pressure. The cone can slip under heavy acceleration in reverse or on the overrun so engine braking should be avoided if the overdrive is switched out. When the overdrive is engaged, the cone clutch is held against the clutch band using very high fluid pressure (about 700psi) so it's not going to slip on the overrun. With that in mind I always slow the car down with the overdrive engaged and let it drop out automatically at about 15mph. The other thing I do now is regularly change the fluid. There's a drain plug fitted as standard to my overdrive so I don't even have to drop the pan and it only takes about half an hour.

So, the system doesn't kick down, aka out of overdrive on accel ? I assume the regular trans still does, so technially the trans is in 2nd , yet the OD is still engaged.
Correct. With my 3:55's on the highway in 3rd OD the regular trans still kicks down at 70 mph and does not go into 3rd until 105 mph if I keep the petal to the floor.

Troy,
I want to thank you so much for taking the time and effort to document this. I scored a nice Gear Vendors unit for $400 a while back with a T-19 adapter. I plan on installing it in my '71 R/T this summer while Levi and Ethan are home on leave from Annapolis. I am going with a simple on/off switch, as I plan on using it as a simple overdrive so I can replace my 2.76s with 3.23s.
Again, I personally appreciate what you did here. As the old saying goes, a picture is worth a thousand words.
May God bless America, "Paladin" Ben H. English Ozona, Texas

GV's website says - Fluid type - GM#1052271 petroleum based or GM#12346190 synthetic.
Ken, thanks for the head's up. The Dexron II ATF is right out of their installation manual. But, maybe it hasn't been updated. It's worth a call to them to verify since I haven't gotten it out on the road yet. I'll try to check out their website this afternoon.

Troy...I read right over the part about you using the Dexron. I originally purchased my GV for a D350 pickup, and installed it in that truck. My installation manual also had the sticker saying to use the GM petro or synthetic. I used the petro oil while it was in the truck. When I bought my 04 Dodge 2500, I pulled the GV out of my old truck and sold the truck. A few years later, I put the GV in my 71 GY3 Challenger. This time I used the synthetic GM fluid, and I'm much happier with the way it shifts. The Dexron probably wouldn't hurt yours,but I'd check with the GV techs to see.

Wow... What a difference....... I drove the Daytona this afternoon making sure all the "t's were crossed and "i's" dotted. Here are two videos of the cruise. Sorry about the quality and only being inside, but can't take outside videos when one's driving..... The unit has done everything as advertised. Engaged and disengaged right on queue. Seemed to drive smooth without any differential adjustment to any driveline angles. So far, quite pleased. I'll put a few more miles on her then check the gearlube and all wires and speedo-cable for any clearance issues...
