Over 18 years of building transmissions almost exclusively for GM rear wheel drive vehicles have proven our expertise. We have transmissions in countries around the globe in applications ranging from stock musclecars to 1500+ HP Monster Trucks !
Our transmissions WORK!
We continuously test new products and design our own.
BIG POWER Street combos are our specialty. If you have a 800-2000 HP street legal car and need an automatic transmission give us a call.
We make the TH400 live at 1500 HP using an automatic valve body. You may have noticed everybody else wants to use a full manual valve body at that power level. That's because they don't have the knowledge to make the transmission live using the valve body GM designed.
Our 4L80E builds are setting the standard for others to follow. Jake's Performance 4L80E transbrake is quickly becoming the most popular item we sell. That's because it blows the competition away on set and release times. Try it, you'll never use a competitors again.
We have the capability of building specialty transmissions for unusual combinations. Need a 4L80E behind a Mod Motor Mustang?, call us.
Congrats to Tim O. for his successful shakedown runs. 8.90 @ 154 mph in his '03 Cobra. We look forward to seeing you get faster! http://youtu.be/a5SS7D0ThnU
In the near future we will release our spragless 4L80E for extreme power (1500+ HP) and for the serious road course or off-roaders who want the ultimate strength and the ability to have full engine braking and automatic or manual upshifts and downshifts.
Contact us with your transmission needs.
All transmissions at Jake's Performance are built with all new friction materials, steel plates, bands, seals, filter, and soft parts at a minimum. Electronic units include new shift solenoids, manifold presure switch, wiring harness, and sensors in most cases.
We do multiple upgrades on every unit. GM automatics are our specialty and we know these units inside and out. We know what usually fails and why. We upgrade the known weak points to prevent common failures.
A typical transmission rebuild shop doesn't build extra capacity into the transmission. They simple "rebuild" the unit and in many cases what they call a rebuild is replacing only the clutches that are burnt or worn. We replace all the wear items, replace thrust washers with bearings (rollerize), upgrade the hydraulics, clutch materials, clutch capacity, blueprint the clearances, and any unit specific upgrades to make the transmissions live.
90% of what we build is for 500+ HP applications. We also do builds for musclecar restoration where the case gets blasted to bare aluminum to appear new and stock.
We have extensive time studying and improving hydraulic circuits. Many shops just use another vendors pre-built valve bodies, transbrakes, and hard parts. We study the parts to look for improvements, select the better component, or design something that works better.
We build transmissions for all out strip cars as well as the mostly street rides. We can help you get an overdrive automatic in your older hot rod to transform it into a more driveable car with better fuel mileage, less wear and tear on the engine, and less noise at cruise.
We have a "mule" car to test our ideas and new parts before giving them to the customer.
We dyno test all units before they ship.
We look forward to talking to you about your combo and helping you get the right transmission for your needs.
