Monkeywrench Racing is proud to offer this expertly rebuilt GSA unit. Leaks are common especially at higher miles so we fully disassemble, inspect, refinish internally and replace all seals. Then the unit is live tested for function and leaks with pressurized SMT fluid on our custom test stand. This is a rebuilt hydraulic unit only, the 3 plastic travel sensors and 1 pressure sensor are not included (sold separately if needed, or reuse your old ones.) The two large  solenoids are included and tested good.

MWR takes the time to thoroughly clean, insect and functionally test the solenoids – we have not heard of any other rebuilder going to these lengths to ensure perfect operation of the rebuilt unit. These solenoids are a common source of failure which may not even happen right away so having full confidence of their operation is vital!

There is a 6 month exchange warranty on this unit. If you install it and have any problems with it within 6 months we will exchange it for another rebuilt unit at no cost.

This unit is the most common failure that causes malfunction of the SMT transmission system. It engages/disengages the clutch and manages shifting the transmission gears.

Be sure to order new SMT FLUID when servicing the SMT system. You must also reset the transmission ECU and perform the relearn function after installation. Any Toyota dealer can do this or it can be done with Techstream software.

Because of the nature of electrohydraulic components we ABSOLUTELY cannot accept any returns for this item. Exchange only in case of a defective unit.

This rebuilt unit is sold with a core charge. You pay the core charge now so we ship the unit to you immediately. Once you have your car up and running you can then ship your old GSA unit back to us for a refund of the core charge or you may keep the old GSA unit. Just mark your order # and CORE on the outside of the package when sending core in and we’ll refund after receiving it. The core can be nonfunctional obviously but

cross reference 33960-0W012 33960-0W011 33960-0W010 339600W012 339600W011 339600W010 – these units are all IDENTICAL and INTERCHANGEABLE
