who do you guys think will be the first to have a 7 speed trans? both manual and auto... my guess is chevy as they seem to be ahead of the power curve in the past in this department... i would love a 7 speed with a little more spred in the gears with some 3.42's out back... and an even lower first...
I wish my current tow rig had a seventh gear, but I think that Dodge should be the first. Not that they will be but they need to be first. The G56 tranny needs another gear. LT.
I think a 6 speed is plenty. With the current autos you have a 6.5 speed anyway with lockup. It starts getting silly to put anymore gears in these things, they are pickup trucks, no Peterbilts. Plus, I don't want the bill to rebuild a 7 or 8 speed automatic.
i asked who would be the first, as we all know it will happen... not what ya think... i would LOVE a lower first, and 3.42's... i DO agree that they are not big rigs, and i know they will never top 26k as a 3500. but like i said, who will be the first as we know someone will do it...
I agree, chevy will put the money into it and they have a good tranny already. Dodge should be the first but they wont be as usual.
Yes it does. My truck runs 2000rpm@65mph with 200rpm increases every 5mph. The overhead shows 19-20mpg @75 but I don't think that's accurate. I think it's not that good. One solution could be the Gear Vendors over/under tranny but it's expensive at about $5000. Anybody else have this problem with the G56?
hmm... i didnt think you were right about this.. so i check... and ford doesnt have a 6 speed. i thought they had. but i was wrong. now, this could go both ways. dodge never had a 5 speed auto, so ford could also be th efirst to go to a 7 speed auto... i still agree that chevy will be the first as allison is always willing to try new stuff... but, i guess in truth, only time will tell.

What I wonder is where is the hp war going to stop? I mean all the new trucks have 100 more hp than they did as little as 6 or 7 years ago. A friend of mine has a 2000 F250, factory hp, 225. New F250, 350 hp . The old 6.5 chevy was rated at 195 hp (I stand to be corrected on these numbers), your new chevy has almost twice that. I mean are we going to see 500 hp from the factory?
The engine builders are trying to close the torque to horsepower gap, which in diesels has been pretty much 2:1, but it's hard to do. Even the mighty Cummins, which can be pumped up over 1200hp, still stays close to that ratio. An 800hp Cummins will put out 1500-1600ft lbs. of torque. The key to closing the gap is getting the motor to stay together at over 3500rpms, which is over redline in the Cummins. Gale Banks is working on this problem with a twin turbo Duramax marine engine. The Yanmar 6 cylinder marine diesel puts out close to 1000ft lbs of torque but only 485hp, making the boats much slower than they would be with gas motors. He wants the Duramax to be 1 1/2:1 or closer. Torque is great for getting things like cars and boats moving but horsepower makes them go faster.
I'm terrible sorry to about that.Is it against the rules? Talking about a seven speed tranny led me to think about that. My thoughts on the seven speed tranny: GM will probably be first. But I still think we will probably see more hp, and imo the two are related.
I am beginning to think it wont be one of the big three. after seeing some of the new Japaneses stuff coming up.
Welp, if your talking a manual it will not be GM as they don't believe in them. Not sure they would do more than a 6 speed auto but you never know.
Yes I do. The gear vendor has really crappy service intervals, and the cost well its out there. I can start in 3rd with no load now and even with most loads second is fine. I am planning a 3.42 gear swap to lower the rpm, then first gear will also become a bit more usefull. Doubt it, since GM sold Allison. There really isn't much of a need for anymore than 6 in the auto's. Now the G56 is another story.
