I did try just mocking it up first with out any cutting and it was not happening at all. I proceeded to cut out a little at a time till I got the transmission where I wanted it then started fabbing it back together. Yah, major modification might be the wrong term, major modification might be a more appropriate term for what I just went thru turning my 91 Ford van into a 4X4 Still, there is a fair amount of work to get that TKO in there And worth every bit of the effort!

I used seam sealer and pop rivets.

I split my tunnel up the middle and made a pie-shaped piece of steel and welded it in place. I had to make a special shifter porch to fit the widened tunnel. I wish I would have got the tranny up another 1/2" or so, but it fit pretty well.
Here is a link of my modifications http://forums.maxperformanceinc.com/...ght=tko&page=2

If I can get a good deal on a LGT-700, I will probably be putting my TKO up for sale. That LGT tranny is pretty sweet.

Anybody know if that TKO600 would fit in 1979 Trans Am behind a Pontiac 455? My car is a original 4spd SE W72 car so I don't want to do any cutting on it.

I have a Doug Nash/Richmond 5 speed I removed from a 79 Trans AM W72 WS6 car, the transmission fit directly in the same place as the original ST10 4 speed with no cutting or hammering, just the crossmember was slid back and used only two holes or I think a TH400 would work to use all 4 holes.

Is there anything special about the Doug Nash\Richmond 5 speed overdrive when buying one? Or pretty straightforward?

I think this is what some people run into when they don't want to face the fact that you have to hack up the floor. If your going to do it take the leap and do it. What the hell is another 1/2" When you already got it opened up? The objective really isn't how little you can cut but rather getting the right geometry from tranny back to rear end. You leave it too low and your asking for trouble, jmo.

.....and if the angles aren't right, it's a buzzmobile.

I had the same issue with pinion angle, I just raised my tranny another 3/8 of an inch and the car is a lot smoother above 90. The 700 is a lot higher toward the back of the trans, which does bring the trans really close to the tunnel.

The rear Trans Mount is in the 67 GTO Turbo 400 location vs the Muncie or Turbo 350 trans mount location. With a "Roof Car" you can typically add a couple of holes in the frame area and get the right location on a earlier A-Body frame. Convertibles are harder as they have a weld on mount on the enclosed frame. When I had the frame out I split the frame mount, removed the rear section and moved it rearward, and added a section in the open middle area. This now allowed me to run a Muncie, a Turbo 350, a Turbo 400, or a Doug Nash in my 64 GTO Convertible. I don't do car shows so 99% of the people would never notice the modded trans frame mount. The driveshaft angles should be about right with the Nash trans as the overall length of the trans is the same, just the trans mount location moved on the trans. Tom Vaught

The Doug Nash has a great reputation - I looked into buying one and was advised against it my my local tranny specialist (guy in upstate SC who used to work for Richmond before they were bought out) as he said you can't get parts for them.
I'd say 1/2 the time I purchase a used "ready to run" tranny it needs work or parts. I just don't see many "richmond" five speeds for sale that are pretty reasonable on cost, etc. |

As a note, Gale Banks ran a twin turbo BB Chevy engine in a 3rd Gen Trans Am at Bonneville. The engine made around 1400 HP. They used a Doug Nash Transmission and a Overdrive add-on. The DNE trans worked fine in the car if it was shifted properly vs Power Shifted and saw High shock loads. Just saying. Tom Vaught

Have little info on the ROD trans Sorry.
Could be identical or much different. Nash used to have a side view of the trans dimensions. Tom Vaught
