Can any describe how Doug Nash identified their transmissions that they built? ID numbers ect.
Thanks

I have a Richmond Street 5 Speed. It has around 2000
miles on it since new. The problem I am having is that it does not shift that great. It is fitted with a Long Shifter, a Centerforce 10.4" Dual Friction clutch, Castrol VMX oil (80w90 semi synthetic). I have been through all the usual stuff with the shifter adjustment and clutch air gap. Is this a typical characteristic of this transmission or can anyone suggest a fix. The transmission has the optional gearset of 4.06 low and 2.22 second.

To Nigel Shaw...The richmond boxes have this bad shifting characteristic. The gears are quite heavy in these boxes making the shift effort high. Try GM synchromesh fluid in the box.

I would like to use the 6-speed in a street/strip/autox aplication. Targeted power output would be in the 600 ft/pound@6000 RPM range. 3500lb vehicle. Will this tranny stand up to occasional blasts down the drag strip or around a road course ?

How does it compare to the new Borg Warner 6 speed in the Vettes and Vipers ?

Thanks for any help

Dudes, I was wondering. Iīve seen cars around the net which have Doug Nash transmissions, but with Hurst shifter... what does all that mean? Is it like, you can use it like a hurst transmission (you donīt have to clutch unless you want to) or what??? :)
thanx in advance

i have a doug nash 4+3 transmision,and when its in overdrive it downshifts back and forth, can anybody help me.

To Bravo: I call this hunting in and out of gear. Look to see that the OD light isn't going on and off as well. If it is, then you have a ECM/signal problem to the OD. If is is not check your solinoid, or pressure switch or connection to them. Most of the time when this happens and your OD light stays on it usually means your OD clutches are fried.

Wanted: Richmond or Doug Nash 5 speed for older project. Must be reasonably priced.

Anyone know where to find replacement parts for a Doug Nash Overdrive unit? I need the electric motor that shifts the O/D mechanism in and out. Thanks

interesting project car. 82 mazda rx7 gt3 race car being shoe horned with 400m ford at around 450 hp. would like info on correct trans for 2km roadrace course. would prefer close ratio of around 2.20,1.85,1.50,1. is a dogged syncro the ticket or would a cone syncro be sufficient. doesn't doug nash make a 5spd with dogged syncros and straight cut teeth, 5th gear would be removed and blocked. space behind engine is limited due the #1 plug being 3inches behind front axle centerline. car weighs 2600lbs with 400 and toploader in the trunk.

I have a new richmond 5 spd, shifting gears is real hard. I went through all the shifter and clutch adjustment ,it still hard. I tried red line Mtl and gm synchromesh fluids and there is no change.What is wrong ??

To Peter, Richmond 5 and 6 speed are horrible shifting transmissions. This is a normal complaint. Your detents and synchros need to be reworked for it to shift nice and smooth.

Dear Paul
I just recently found this web sit. I have been interested in Nash/Richmond 5spds for sometime, have wanted to put one in my 66 Corvette,it has 3.08s in the rearend now. A lower 1st gear sure would make things more fun. I also have a 69 SS396 Chevelle that I was thinking of puting a Richmond 5spd in, but now I'm not so sure thats what I want to do.
What do you have to do to the detents and synchros?
to get them to shift smooth, Corvette does not get abused,but my Chevelle does occasionally. Will these mods allow me to power shift my Chevelle.
Thanks,Gene

I have a new richmond 5 spd . The shifting is a little better after i put some miles on it but (75miles) , it is still not what i am use to.I am willing to sell it for $1500 with shifter, I paid $2300 .It is time for a M22 again. email pstillo@sandyinc.com
My friend has one in his chevy and loves it.

On Richmond 5and 6 speed shifting fixes as of december 1st this site will move to 5speeds.com. I will post a fix with pictures on the new site. It's too detailed to explain via email. --- paul
