TKO 600 vs T56

[sinned]

Honestly on the freeways around here you'll find yourself "hunting" between 4th, 5th, and 6th.

Just my opinion, I've driven more than my share of Vipers and there are just too many gears. The added weight and expense doesn't seem worth it.

D&D is the best place to buy a good box.

BTW Ned, I'm 30 miles west of you, let me know if you are going to the next p-town show...I'll keep an eye out.

Hi guys, Last time I heard D&D was unable to sell viper T56's, any truth to the rumor on this? Seems Diamler is not liking them used in the aftermarket? 6th is nice to have when you need it...i've used it plenty
Pleasanton, its coming up in March, get ready guys...Den you gonna be able to come out and play? Vin

Considering that D&D was selling new Viper boxes for 800 less than our dealership pays cost to DCX do you wonder why? I hear they are building T56's to Viper sepcs and selling them that way.

Are you kidding....my wife asks everyday how much longer until she can get out of the house on the weekends again. See you guys in March.

If you have the funds I have a great idea..

How about a TKO 5 speed and a gear vendors overdrive?

I didn't even know they make them to fit on manual transmissions. the 5 speed will be a lot stronger than the 6 speed and the OD will get you the milage.

You will also have more gear selections.. This is what I am thinking of doing on the 68 since the torque of the big block would beat a T56 to death (and I already own a gear vendors unit).

Might be a good option if you are going to be making lots of hp/tq..

For that matter you could do a T10 (inexpensive) and a gear vendors.. od would be .78 i think.. dont quote me though

Or if you like you M20 you could hook a GV to it as well.. I think they are good for 1100hp and pretty much never brake. You would need to shorten the driveshaft though.. I know the unit is a bit price but it is an option and it also has almost zero drivetrain loss (though it does ad weight)

A Gear Venders unit might be good for 1100hp but I'm not sure T10 or M20 could handle half that much.

It's strictly a trademark issue. I just talked to D&D the other day about this and was told they still have quite a few Viper T56 trannies in stock for the foreseeable future. However,they are in negotiations with Chrysler to resolve the problem.
I've got one in my 69 El Camino and it works really well with 4.11 rear cogs.
6th gear is strictly for highway fuel economy.
