#GEARCO 8400 TRANSMISSION MANUAL UPGRADE#

We have several upgrade options for the various stages of 4L80E.В We offer two different transbrakes. We have more experience than any other aftermarket shop building 4L80EвЂ™s. If you have a 500+ HP musclecar, late model LSx powered car, or other combo that demands THE bulletproof trans, we can build it for you. We specialize in building the 4L80E for retrofit applications. Our valve body hydraulics have proven themselves repeatedly and our transbrakes have set the standard for release time.

We have established ourselves in the industry with our exclusive innovative 4L80E valve body designs whether we use our in house recalibration kit, or one of our transbrakes, you are getting what no other company in the industry has. They include all new friction clutches, bands, steel plates, soft parts, filter, modulator (if applicable), as well as hydraulic upgrades, bearings added at several thrust locations, and other modifications depending on power level. Look for some innovative new products in the near future that should make the 4L80E even stronger.ДЄs with all JakeвЂ™s Performance transmissions they start with a select core that is disassembled, the case is hot tanked, pressure washed, inspected, painted and prepped for reassembly. Most of our development time is spent on the 4L80E. The 4L80E has proven reliable like itвЂ™s predecessor. We have built them for applications ranging from heavy towing vehicles to 1800+ HP street/strip cars.

At JakeвЂ™s Performance the 4L80E is our most popular transmission. It shares many components and design features. The 4L80E is the descendant of the вЂњOle ReliableвЂќ TH400 transmission. If this makes sense to you, take a look at our 4L80E options below. We just want to be sure you get the strongest option available at the best price the first time.

Other builders are afraid to cut into their sales and tell you this. We specialize in 4L80Es because we KNOW it is the only real option for REAL power with reliability. But there is more demand for 4L80s, so business wise, it makes sense to pursue that market. We could build and sell a very well built 4L60E that would compete with anybodyвЂ™s on the market. Have you broken a Level II, V, or MXXVII 4L60E that is supposedly 700 HP capable with 450 HP? Multiple times? Have you ever read a build list for a 4L60E/65/70 and wondered why it sounded like everything in the trans was replaced for a performance build? That is because itвЂ™s the wrong unit to use in a big power application.
