Toyota, Lexus and Scion full system scanner with bidirectional control, so you can command U660E solenoids and read live ATF temp off the TCM.
Toyota and Lexus automatics have a habit of turning a simple job into a guessing game. The six-speed U660E and U760E in the Camry, RAV4, Highlander, Sienna, Avalon, ES350 and RX350 have no dipstick, set their fluid level by temperature, and hide most of their shift behavior inside the transmission computer. The XTOOL IP500 for Toyota is a full-system scan tool built only for Toyota, Lexus and Scion, with bidirectional control, so you can see what the TCM sees and command its outputs instead of reading a code and buying parts on a hunch.
These transaxles shift with linear solenoids that the TCM pulses constantly, and they run the converter clutch in a controlled slip rather than a simple on-off lockup. That makes live data the real diagnostic. The IP500 reads and clears codes across the ECM, TCM, ABS, SRS and body modules, graphs live data while you drive, and runs active tests that command solenoids on the lift. On the transmission side the useful values are fluid temperature, input and output speed, gear commanded versus gear attained and converter slip. It connects at the OBD2 port and needs no subscription, and software updates are free for the life of the tool.
Our U660E and U760E problems and service guide explains each of these complaints and the order to chase them in.
Run a full-system scan first, because a throttle, MAF or misfire fault can drag shift quality down with no TCM code. Next confirm the fluid level at the correct temperature; Toyota's level bulletin is written around reading fluid temperature on a scan tool, and a level set cold or too hot creates shudder and flare on its own. Then road test with commanded gear, converter slip and fluid temperature on screen and note exactly where the complaint happens. Back on the lift, use the active tests to command the shift and lockup solenoids. A solenoid that does not respond, or a circuit that reads out of range, points toward a U760E solenoid kit or the U660E converter clutch solenoid. Solenoids that respond while the complaint stays usually means worn bores, and a U660E valve body is the fix.
This is the Toyota-only build of the IP500 platform. It covers Toyota, Lexus and Scion, including the U660E, U760E, U250E, A750E, A760E, AB60 and the UA80 eight-speed transmission modules. It will not diagnose GM, Ford, Chrysler or other import brands. Specific functions vary by model and year, so if you have an unusual or older vehicle, send us the year and VIN and we will check coverage before you order. For parts for the six-speed transaxles, see our U660E and U760E parts collection.
Our U660E fluid type and capacity guide has the full level-set procedure, plug torque values and the WS part number. If the pan comes off during diagnosis, pick up the U660E filter and pan gasket kit for the reassembly.

Yes. It reads live TCM data, including fluid temperature, which is what Toyota's WS level procedure is based on. The overflow plug check is only valid with the fluid between 185 and 194 degrees F.
Yes. This version covers Toyota, Lexus and Scion. It does not cover GM, Ford, Chrysler or other brands.
Yes. Bidirectional active tests let you command outputs such as shift and lockup solenoids with the vehicle stationary, as supported by the specific model and year.
No. Software updates are free for the life of the tool.
Function support varies by model and year. Send us your year and VIN and we will confirm which transmission resets and tests are available for your vehicle before you order.
