    Thumbs up New 700/60E bits.

    Found this last night, figured I'd post here too:



    You guys know I piss and moan about the **** ratios the unit has and rave about the 200-4R's, well... looks like Transmission Center finally addressed this. I've emailed for prices on the planets, hopefully they're under $1k.

    Has a serious OD ratio so you'll need some gear out back (sounds like I'll be on 4.56:1 gears) and I can sell my five pinion planets to some cat that wants them.

    No more near 47% gear ratio drop (3.06/1.63/1), now only around a 41% drop (80E has around 40%)... and a killer OD



    "The Next Big Thing".

    PATC has developed a 6-pinion planet gear set for 700R4 / 4L60E transmissions. This will be the biggest thing in 700R4 advancements in years. These will have a 2.66 to 1 first gear, 1.55 to 1 second gear, 1 to 1 third gear and .64 to 1 overdrive ratio.

    This is a 36% overdrive making this one of the best overdrive ratios around. The 1st to 2nd RPM drop between gears would be slightly less than the RPM drop on a 200-4R transmission. This is what people have been asking for, for years. These will work on any 4L60E type transmission without a gear ratio error code, if the PCM is modified. This gear set is used to reduce torque multiplication / rotating speed in the transmission in first gear. This improves track applications that overpower the rear tires upon launch. This is common with numerically high final drive ratios. (IE 3.06). Now you will have a choice between the wide ratio or the new close ratio gear sets.

    It has been reported that the 2.66 gear set could lower your quarter mile time as much as 4/10 of a second over the 3.06 gear set. Plus better mileage and lower RPM with the .64 to 1 overdrive. The first 50 are in production now and the approximate release date is 2-1-2008.



    Also, I heard a rumor of a Titanium input drum. More 3-4 clutches and no ripping of the shaft from the drum. Asked about that too.

    Okay here's what they said:



    The planet gears will be ready real shortly. All you have to do to change the gear ratios is change the front planet. They could be ready as soon as next week. We can't get the titanium drum for about one year and yes it will have larger clutches.

    sounds promising. But with the added cost of the new planetary gears, your spending just about the same for a fully built 80E, and these new gears wont make the 60E any stronger will they?

    And why do you need a fully built 80E?

    If the 60E is built right it can hold some huge power.

    ****, pushed back a month But any concern of strength loss is out the window.

    The sun gear is made from 4340 billet steel and the pinion gears are 4130 steel. The pinion gears are .180" larger and have 18 teeth instead of 14 teeth found on 700R4 type transmissions.

    This gear set is used to reduce torque multiplication / rotating speed in the transmission in first gear. This improves track applications that overpower the rear tires upon launch.
