Well, it took quite a while but my new transmission finally arrived this past Friday. It's a G-Force T56 with all the goodies. This thing looks plenty beefy. Hopefully it will be up for the abuse I plan to dish out I can already hear those Isky Red Zone lifters crying for oil at highway speeds with the .51% overdrive I'm not sure how much I'll actually be able to use 6th gear, but it will be nice to have if the need arises. Here are a few pictures. The transmission beside the T56 is a TH-350 that I built for my dad over the weekend. It's going in a '55 Apache project that he's working on.

Nice lookin parts!

A couple of nice looking pieces. Care to share how you got the TH-350 case to look so nice? After I build them they look clean but not that good.

Now you can hope on the ATL bypass and do ~90mph over to Commerce.

As long as that thing is, are there any weight savings if we disregard the clutch/converter components as compared to a TH400? I reckon the fluid capacity in a manual is less...

Thanks, Scot. I used a fine 3M roloc to go over the case. Then I used a high build primer (3 coats). The top coat is Eastwoods alumablast (3 coats). I've got to go back and prime paint the governer cover and latch. I was just too tired after working on it all day. I normally wouldn't go to those length to make a transmission look that nice, but my dad's truck is a frame off deal so I wanted the tranny to look as nice as possible.

Yeah, Mike. It should be a cruiser. As for the weight.... The shipping documents said the tranny weighed 130 lbs. It holds 4 quarts of fluid. The bellhousing (Lakewood) weighed 28lbs, and the clutch assembly (flywheel, clutch and pressure plate) weighed 22lbs. I think the TH-400 weighed ~135lbs. Not sure how much the converter weighed. I think the manual setup is a little heavier.

 

[40Coupe]

Yeah, well I hear there's a bunch of guys down at Z-town that don't think you're the hot stuff.....heard one says to bring that Chevelle down when you get it done....he's got something for ya.

Great looking trans. I plan on doing the same swap later this year. What rear gear are you going to use with the 6 speed? I will change the 3.90 over to 3.42 when I get my 6 speed.

I'm going to stick with the 4.11 gear that's already in there. I think I calculated the RPM at 2,250 at 80 MPH in 6th. Hopefully the cam won't be lugging at that RPM

Thats really sweet. What is the HP threshold on the T-56? I have often day dreamed of a 6 speed.

Shawn,

This unit is rated at 800ft lbs. There are quite a few heavy weight cars running this transmission making much power, though. The Underground Racing Twin Turbo Viper clocked an amazing [email protected]+ MPH with this transmission. I'm told the race weight was ~3,600lbs. I'm hoping it will work well.

 

[Shawn Gilbert]

That is going to be so sweet man!!!! you need to get us some in car video with that!!!!

That looks delicious! Keep us posted on the install; you could be the first to do a full write up! <hint hint!> =)~

Is that Chad Williams' yellow Viper from the 2005 Pump Gas Drags? In an update in the April '06 issue (page 36) it ran a 7.99 @ 177 but it no longer sports the six speed. According to the update on page 36 it now has a T-400 transmission in place of the standard six speed and is considerably faster and quicker rhan when it appeared at the PG Drags.

Harold,

The Viper I mentioned is owned by a guy named Garth Weaver. I was incorrect. The car actually ran a [email protected] Here are some videos:

This Viper made 1,564 RWHP. The fact that the G-Force 6 speed can hold up to launches behind an engine making that kind of power in a full weight car is pretty damn impressive to me.

There is no doubt in my mind that an automatic transmission vs. a stick transmission in an otherwise identical car will run quicker (not faster) 99% of the time. I've been there and done that. If the sole purpose for my car was still racing I would have kept the automatic. That said, I think my car will still be pretty quick with the 6 speed and it will be super streetable :thumbsup: I still have the TH-400 (freshly built with lightened internals) and a brand new still in the box Coan 9" steel stator convertor if I ever want to run the car "on kill", lol.

That is definately one fast Viper. The yellow one in the introduction was the one that ran at the PGD and formerly had the record. That red one is definately covering the 1/4 mile in a hurry. Great video by the way. I'm amazed the tranny can hold up under that much torque. I've heard that the way a Turbocharged engine delivers the power that you can get away with things that you can't with a nitrous car, torque comes in a lot smoother.

I'll let you know this time next year
