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 it's the wrong unit to use in a big power application. We're not here to mislead you. We could build and sell a very well built 4L60E that would compete with anybody's on the market. There is more demand for this unit, so business wise, it makes sense to pursue that market.
We specialize in 4L80Es because we KNOW it is the only real option for REAL power with reliability.
Other builders are afraid to cut into their sales and tell you this. We're not. We just want to be sure you get the strongest option available at the best price the first time.
If this makes sense to you, take a look at our 4L80E options below.
The 4L80E is the descendant of the "Ole Reliable" TH400 transmission. It shares many components and design features. At Jake's Performance the 4L80E is our most popular transmission. We have built them for applications ranging from heavy towing vehicles to 1800+ HP street/strip cars.
The 4L80E has proven reliable like it's predecessor.
Most of our development time is spent on the 4L80E. Look for some innovative new products in the near future that should make the 4L80E even stronger.
As with all Jake's Performance transmissions they start with a select core that is disassembled, the case is blasted clean, hot tanked, pressure washed, inspected, painted and prepped for reassembly. They also 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.
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. Our valve body hydraulics have proven themselves repeatedly and our transbrakes have set the standard for release time.
We specialize in building the 4L80E for retrofit applications. 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 have several upgrade options for the various stages of 4L80E.
We offer two different transbrakes. Both designs will work in a stock depth pan.
Our D1 transbrake, also known as the Manual Low transbrake, allows normal reverse operation but requires the gear selector to be in the 1st or low gear position to operate. It is a very quick acting transbrake. It works very well in full manual configuration. It has some special tuning considerations for use with a controller in an automatic shift situation.
Our D3 transbrake allows for transbrake operation in any forward gear range. It requires transbrake activation for reverse. It works very well in automatic computer controlled applications because the shifter can be left in D3 and the controller shifts the transmission, instead of requiring the driver to shift from D1 after launch.
We also offer 6 pinion heavy duty 2.75 ratio gearsets for $1000 additonal. These work well in heavy vehicles and some towing or 4x4 applications.
We offer 2.10 ratio gearsets for $1700 additonal. These work well in big power drag racing combos that need to tame the launch.
Aluminum Direct Drum Upgrades for high rpm combos.
$550 for 34 element sprag aluminum drum.
$850 for 36 element Super Sprag aluminum drum.
Mechanical Speedo Conversions are available for $550 additional. This allows cable driven speedometers to operate with the 4L80E.
The Street/Strip (Stage 2) 4L80E includes all new friction materials, steels, bands, rollerized forward hub, rollerized output shaft thrust, heavy duty intermediate snap ring, 6 clutch direct pack, Hi-Energy carbon clutches in select locations, hydraulic modifications for much increased power capacity and firmer shifting. All 4L80Es also include a new boost valve assembly, new shift solenoids, manifold pressure switch, internal wiring, as applicable.
All pricing excludes core cost. See below for core cost.
