Tremec 6060 in a Gen. II?

[GTSjbud]

I would like to install the new Tremec 6060 transmission out of a 2008 Viper into my Gen. II Viper. Has anyone done this? Can it be done?

Look forward to hearing input!!

I've been wondering about compatibility of engine and tranny from the 08 to a GTS as well. Anybody?

I was looking pretty seriously at doing this. the only problem: no provision for a speed sensor on the tremec 6060 .

So it can't be done?

I think that RobZilla did something like this with gen II roadster not too long ago. Check with him

He used a Gen 3. Whatever that tranny is.

I have just sent an email to Tremec to see if the 6060 could be installed in a Gen. II. I will report my findings once Tremec replies.

Cheers

Gen III's are still T56 transmissions. If the bell housing will line up with the '08 6060, it should be doable. Just tap the back housing for a spedo sensor and enjoy.

We have not made this swap but as Rob said it should be an easy swap. You may need to have the driveshaft shortened a little or different yolks can be used to compensate for the length change.

Here is a reply from Jeff at Tremec:

"The TR6060 “Viper” should be a direct bolt in, with the exception of...

The Gen II has a speedometer gear and speed sensor. The newer Vipers do not. The speedometer is run from the rear axle.

The TR6060 uses a thicker or double wall slip yoke. The slip yoke from the 2005 Dodge Ram SRT-10 is the same.

Reuse the Gen II bell housing."

Suggestion: the Cadillac CTS-V with the 550hp supercharged engine also uses the 6060 tranny - only the Caddy has the much better .80 and .63 5th and 6th gear ratios. I have no idea of the input shaft etc is different, but I'd check to see if that version would be an option, or have the shorter 5th and 6th put into the Viper version. These shorter ratios where previously only available sourced from the Aston Martin Euro-only version of the T56 tranny.

I had the Euro Aston Martin gear 5th and 6th ratios done in my T56, was the way to go. John Donetto's your man for that.

I have also done some speed sensor work, I worked out a toothed gear-wheel to press fit on the front slip yoke, and then made a bracket to take the OE speed pick up sensor part#04848214. To read it, this distance / clearence from the cog teeth is important. I did go all tech on it, and had an elctronics aircraft mate measure the sensor wave, it was a 5-volt square wave about 7hz per mile from memory (hz is number of pulses per second per mph, for enquiring minds)! You can work out the toothed wheel required from this given the tire OD per revolution, the distance you move forwards, then it goes to maths with inches a mile and inches a turn of the wheel, multiplied by the diff ratio...blah blah. Anyway easy option to check, is pull the sensor and look at the little speedometer gear, and measure and count 10 teeth! Later ones use ABS for speed pick up...interesting 33 teeth, given diff ratio, will get measured that wave and hz it reads at.
