If I were to offer a reverse upgrade and it would cost $1500.00- $2000.00 more on top of the current price.
Would you do it?
This would also change your sift likage to the passanger side of the gearbox, and the length of the gearbox by 1 1/2".
MD4S- 2D current price $7500.00
MD4S-2D with upgraded reverse price $9000.00-$9500.00

I'd pay 1500....
It costs that to R&R and repair if it breaks as it is..



I take this back.. OSG makes a good point below...
My trans was already close to 9k after all the upgrades, that would bring it up to 10.5k..... FFF that

nope... haven't broke it in 4 seasons (knock on wood) I know it is a weak link and treat it accordingly.. for 9K+ I would upgrade to a S4 for the difference..

I'm on the fence because I dont have enough time on my box. I to have not broke it yet. If I ever did I would think about it. Because I have an AJ Speed shift I would have to redo my shifter.

What do I want..

If given a choice, I'd have a "Planetary Style" reverse, no more issues..

Also if your going to have to change the shift linkage location could you make a sequential shift pattern available?

There a company that makes a new nose cone that allows sequential shifts.. Just read about it in Sand Sport.

I personally would not even consider it. I would step up to the S4 waaaaay before paying 9.5K for a 2D.

X2, thats exactly what I was thinking!

I have one it is made by AJ SpeedShift.

Never broke one, 2 seasons old. Sorry man, for that much extra money, I think I would lean towards another competitor, we should not have to pay for bad design.

I am always real careful in reverse and never broke it but I did manage to break 3rd, but I wouldn't pay that much more for a reverse that worked. I would step up to an S4 for that kind of money.

When this one breaks, notice I didn't say if, I would like to go to, or at least try the Auto that Transaxle Engineering does.

X2, not that I ming shifting, just easier I guess...

What about a 2D with a higher HP and torque rating? The case could be longer and wider as long as the mounts are the same. I would think that there are plenty of people who would like to upgrade to a stronger transaxle but do not do it because of all the fab work necessary. The expense saved in fab work and powder coating would probably be more than the additional cost of a stronger 2D.

I never had an issue with my 2D and Reverse...... I blew up 1st, 2nd and R&P. Not enough tranny for a heavy or medium HP car. I would spend a little more and get a S4 or even better, a little bit more and get a Fortin.

What would the price difference be between the new 2d and the current S4?

What he said X 2

WOW $9500 for a 2d. No a fence but I would put in a used Fortin for that price. The reason why is that I can add more hp to my car and be fine if I were to pay$9500 for a 2d than I am pretty much in the same boat but with a gear that I don't use that much. My suggestion is if people want to had a bigger reverse then I would increase the case size and make it where the 2d can handle more power then I bet more people would be up for the upped cost. My 2d is three seasons old and knock on wood my reverse is fine so far. Just like Osoto said just know how to use and when. I don't use it like some peeps just to back out of the trailer and a little around camp if needed. Just my 2 cents.

Sounds like most peeps would just go S4 before putting more money in the 2D. I think if you offered an upgraded part that a few would do it but is there enough interest to make it cost effective for you to build.

I will say this though. Those that are complaining about a bad design are misguided. I think if you put out a product and it's properly used as designed and it fails then the manufacturer is at fault. If you build a item and it gets used improperly then the user is at fault.

That being said. I think the 2d is good for a much lower hp then most are giving it. You could probably run 300 hp to it with a 1800-2000 lb car and smaller paddles and it would serve it's purpose just fine.
And then for more Hp, weight or bigger paddles then you have to step up to the larger more expensive trannies.

X2!!

nope, i went with the S4 instead.

I think torque is really the factor. My car makes 300 at the wheels so lets say 415 at the crank. My v6 with the turbo doesnt have the grunt that an ls motor has with the same HP. It applies the power differently. Of course the smaller paddles help save the tranny also.


What would it cost for an existing 2d owner like myself to buy all the pieces to upgrade when rebuilding my tranny next time. I could easily make new motor mounts and move the motor back. Not sure about axle length and assume it would need new ones. I have never broken a reverse but it would be nice to have out in the dunes to be able to back up in the sand. My guess is the price will be too high to be cost effective. I wonder how much difference it would make in moving in my case 440 lbs back 1.5 inches in the handling of the car.

There is another "new " style trans coming out that I would personally go with. Anybody that knows me knows how much I preach about one particular transmission, and this one is a baby version of my favorite trans and comes with a real back up a hill with no worries reverse, for similar money to what this post is asking, so for me the answer is no I would go another direction for that money.

spill it John.

I already sent him a PM cause I'm curious also.

It's more fun this way!! OB shut your mouth... What is my favorite transmission? I preach about it on every what should i buy post I see. What trans is in Paradigm????? The new trans is nick named " A Baby ______". Its not that hard guys!

You guys are killing me, its not that hard..... I don't want to screw up this thread for it's poster so that's all I'll say about it. Sorry Victor, not trying to hi jack your thread. I think lots of D people would pay to upgrade an already owned 2D.... For the right money I would upgrade mine.

I hear ya don't want to mess up this thread but am always looking for away to up the hp on my car and not spend a fortune doing it.

heard it might be a 6 speed...

What he said! I'm on my third ring and pinion, second mainshaft, 3rd 3rd gear, 2nd 4th gear, and the ORIGINAL reverse. That's after 7 n a half seasons. Reverse just IS NOT A PROBLEM unless you are ST***D imho.

I talked to weddle.. not worth it.. they were trying to hold down the price buts its still pretty high. It also is not a big hp trans.

I think instead of upgrading a 2d you should have a recall and fix them all for free.

What if you were building a new buggy? Is this better than a 2D??

John's preference is ALBINS.

Weddle told me no. and its a cable side mount.. so another 6 hundred on top of that.
There in a bunch of test race cars so far.

So do you think that if a guy buys a 1/2 ton pickup and puts 2 cords of wood in the back and it breaks that the manufacurer should recall it and fix it for free? Or do you think it's the responsibilty of the buyer to purchase the right product for the right application. Could have bought a 3/4 or 1 ton truck and not had the problem.

Just sayin'

What size is the reverse in the new Mendeola box? (LQ456)
Woudn't that be the way to go instead of a new reverse in the 2d?

The reverse is larger than the MD4 and comparable to the S4.

The gear stack and reverse are stronger than the MD4.
This is possibly an option to the reverse problem some people have.
