TREMEC 7-Speed Dual Clutch Transmissions

[JAJ]

So, here's the brochure for Tremec's new TR7007 transmission for the updated GT350 and the TR9007 for the upcoming GT500:

There will also be a 7-speed manual available as an option:

The 7-speed manual has a sensor to tell the ECU which gear it's in for *perfect* rev-matching.

Or am I just making this up... we'll see!

6 speed is enough for me. I remember seeing a 6 speed for the first time in a Corvette at a raffle years ago and was TERRIFIED as I was used to a 4 speed. I remember saying to myself how could I possibly drive that! Fast forward to today and my Boss And couldn't live without my 6 speed!!!..........I'd be bored to death with a 4 speed. There are 8 speeds available out there now also....I think that would be too much chance of missing a gear?

Oh yea bring it on. I’d prefer this over the 10 sp auto anyway. I’ve driven several sports cars with a DCT and I’m all in.

@BigTaco did you see anything on this st SEMA?

WoW it will be exciting to see how this plays out. Im all in with DCT but I love my 3rd pedal.

Nothing about it at SEMA. I spoke with some of the Ford Performance guys and there wasn't even a GT350 out there except for the track attack cars

What do you mean updated GT350?

 

[302BOB]

SEMA is a BIg deal to spread your news! I'm very surprised Ford didn't step up to plate and provide some info?..And not even have a GT350 on display????......Somebody was sleeping..................

It's all guesswork at this point, so here's what I'm guessing: I'm guessing that these new Tremec DCT's are going into Ford, Chevy and Dodge cars. Front engine, rear drive cars with big engines. Tremec wouldn't design a whole new line of transmissions "on spec", so it's certain that they've got customers for them. It's just that the customers haven't announced the cars they're going to put them in, so I'm guessing front-engine, rear drive Fords like GT350 and GT500, eventually migrating down to the Mustang GT. Basically anything that can use a TR6060 or 3160 could get upgraded with one of these. I wonder if MGW will bring out a line of shift paddles to go with them...

 

[VoodooBoss]

Ford doesn’t typically make announcements about production cars at SEMA. If an announcement was coming look for something at the L.A. Auto Show.

@JAJ i like your thinking.

 

[BigTaco]

There were no GT350s at the parts truck but they had several of them out for display as part of the “Ford out Front” activities. Trust me, no one was sleeping. The GT350s were the cars driven by NASCAR ford drivers giving hoon rides to VIPs.

 

[VoodooBoss]

So of course you got a hoon ride then...

 

[BigTaco]

It was offered but the timing did not workout...

If they put this in a Mustang I would pay an extra $1500 fo it. Not sold on the 10 speed slush box yet.

The 10 speed seems to work fine in the ZL1. My only concern is how it would hold up to hard core track use.

 

[steveespo]

Exactly. Things are usually fine for magazine tests but some of us are pretty hardcore at the track and put many hours a year on track. Changing that transmission will also be very spendy if warranty is denied.

Even though I have killed a flock of MT82 boxs. A huge part of the appeal of the Boss is shifting for yourself and smiling while you do it. I drove a bunch of Audis at the track with DCT and really did no like the experience much.

Is it true that the new 10-spd auto box switches to 6 when on the track???

True, but this is Tremec, not Getrag. As much as the mainstream Tremec boxes can be a bit finicky, they're pretty robust compared to pretty much everything else. I would expect no less from a wet-clutch DCT from Tremec. With a big enough coolant pump and radiator, it'll be fine. Besides, there's a 7-speed manual in the lineup now too.

I hadn't heard about that. Sounds interesting. Of course, you mean that the computer is programmed to use only 6 speeds in track mode, not that every time you go out, 40% of your gears quit working, right?

I can’t see this as correct. How do you take 4 gears out of 10,not use them and still get good response? Your not taking the last 4 gears away with this scenario because on some tracks you will want your top gear 1:1. Taking and skipping gears on the way up to top gear doesn’t make sense either since it defeats the purpose of a 10 speed which is for close ratio shifts.

From what I saw in R&T

"What's interesting is just how much spacing there is between some of the gears. Through the first six gear ratios, every gear is very closely spaced, clearly aimed for maximum power output and performance. But as the car shifts into seventh, the RPMs drop significantly, indicating that gears seven through ten are optimized for economy driving. It's like having a close-ratio racing gearbox and an economy-minded transmission all in one."

A seven speed solid manual would nice, but as it is I am only using 3rd to 5th gear on the track. The engine pulls great from 3500 to 7500 rpm.

A friend of mine had at least a half dozen instances on temperature warnings in his 10-spd ZL1 at VIR this weekend. He was very fast (2:05 on Main I think), but still on OE brakes and tires. He’s trading it for the ZL1-1LE.
