  The enhanced 4eat Phase I four speed automatic transmission was used in Subaru vehicle model years starting in 1990 and ending in 1998.  The quantities of clutches in the clutch packs of the factory units varies by model with higher output engines and heavier vehicles requiring more clutches in certain clutch packs.  In our rebuild we increase the quantities of clutches in all models to hold much more torque than the best factory 4eat ever could.  We also use a more advanced clutch material with a higher coefficient of friction to further reduce slippage under high load and much higher resistance to wear.  We also increase the apply pressures presented to the clutch packs to further increase their torque carrying capacity.  The combination of all 3 measures together greatly reduce slippage and as a result transmit more engine torque to the wheels while greatly reducing wear to the transmission.

There are a number of  points of failure in these transmissions which cause weakening of clutch apply pressures and result in frequent high clutch and transfer clutch burn out.  Most of these are the simple result of age and wear.  Some are hard to get parts or hard to get to parts that are often ignored during a rebuild.  All of these parts are replaced in every transmission we rebuild.  Every seal and every solenoid is replaced.  Upgraded seals are used to address problem areas.

A quality remanufactured torque converter of OEM specs is included with each transmission.  The transmission is shipped in a well engineered hardwood crate, the box section of which removes in one piece after removing the screws along the bottom edge.  The boxed, new torque converter sits on a shelf/brace which aligns and braces the transmission inside the crate.  With the torque converter removed the shelf/brace is now free to be removed after which the transmission is free to be removed.  There is absolutely no disassembly of the crate required other than removing the screws which hold the box section to the pallet section.  Your core transmission and torque converter are packed just as easily into the same crate for return to us.  Shipping can be arranged through us at our discounted rates and deducted from the core charge.

We've found that supercharged SVXs can and do sheer the inner transfer clutch drum off of the drive gear.  For extreme output applications like this we offer and recomend a modified drive gear and transfer clutch drum assembly.
