#CGM. Cummins 4BT / 6BT to a Chevy 4L80E / 700R4 / 4L60E / TH400 transmission, billet aluminum transmission adapter and billet steel flexplate. Fits 2002 back, 2003 up available. We have a computer to control a 4L80E / 4L60E transmission. This Cummins adapter and flexplate Combo Kit is light years ahead of the used adapters on the market that don't fit correctly. Call 1-888-8771008 with questions. This adapter uses a 6 liter Ford Power Stroke starter. If your Cummins engine has a standard transmission flywheel now your flywheel bolts will be too long for the new automatic transmission flexplate. You will need new shorter flexplate bolts.

"The Next Big Thing". PATC has developed a new 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. 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. 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 48 are in production now and the approximate release date is 3-1-2008.

PATC is on the cutting edge of performance rear wheel drive American transmission development. We work with different manufacturers in the development of stronger parts. We have the most complete inventory of performance transmission parts for Ford, GM and Dodge than you'll find anywhere else. Using these parts we have developed performance / heavy duty transmissions in many different levels and types. This is why three to four thousand people visit one of our seventeen performance transmission websites everyday, making PATC the number one performance transmission destination on the Internet. These websites are updated sixteen hours per day seven days a week. We don't just sell transmissions and parts, we test them in our test vehicles on the street and at the drag strip. We have the hard to find performance transmission parts all in one place and in stock. We sell the total package, not something that will cost more in the long run or cost more after you buy everything you need one part at a time. Our customers know if we don't have what they need we know who does. On this Website you will find many performance / heavy duty automatic transmission parts the others don't sell.
