A750E Valve Body 2006-2018, remanufactured and ready to install. Fits the A750E. Ships fast from the USA.
Two-wheel-drive Toyota trucks and SUVs with the A750E five-speed automatic tend to tell you the valve body is wearing out in a few predictable ways: the 2-3 shift starts to bind or bang, upshifts flare under load or towing, the converter clutch shudders at light throttle, or the check engine light comes back with P2757 no matter what gets replaced. This remanufactured A750E valve body is listed for 2006-2018, covering the long middle of the A750E's production run in rear-drive Tacoma, 4Runner and related Toyota models.
The A750E is Aisin's electronically controlled five-speed for Toyota's rear-wheel-drive trucks; the A750F is the four-wheel-drive version. Inside, the valve body sits under the pan and does all of the hydraulic decision-making. The pressure regulator sets line pressure, the solenoid modulator feeds the solenoids a steady supply, and shift valves route that pressure to each clutch and brake as the transmission computer fires the shift solenoids. The SLU solenoid and the TCC relay valve handle converter clutch apply. Each of those valves rides in a machined bore, and on a truck with years of towing, heat and stop-and-go use, the bores wear oval and start leaking pressure that the computer cannot compensate for.
Do not skip the basics. These trucks use Toyota WS fluid, and many have never had it changed. One documented case involved an A750F Tundra that kept setting P2757 after the shop replaced the converter, then the valve body, then the SLU solenoid, and the code still returned on long highway drives because of the condition of the factory WS fluid. Our Toyota Camry and Tacoma transmission service guide covers that case and the correct Tacoma fluid, including the transfer case on 4WD trucks. Check fluid level and condition, read live data for commanded versus actual converter slip, and look for debris in the pan. If the fluid is fresh and the codes or shift complaints persist, a worn valve body is the likely cause.
This listing covers the A750E from 2006 through 2018. The A750E is the two-wheel-drive version, so a 4WD Tacoma, 4Runner or FJ Cruiser has the A750F, and you should confirm which one your truck has before ordering. The Tacoma moved to a six-speed with its 2016 redesign, so a 2016-2018 Tacoma will not use this part. The A750E also went through internal revisions during this span, so compare the casting numbers, solenoid layout and harness connector on your old valve body to the listing photos, or send us your year, model and VIN. For earlier trucks, see the A750E valve body for 2003-2007 and the 2005-2009 version.
Drain the pan, remove the filter, and disconnect the solenoid harness and the manual valve linkage before removing the valve body bolts. Record the position of each bolt, since they are different lengths. Clean the pan and magnets and install a new filter and gasket so old debris does not reach the new valve body. Torque to factory spec in sequence, refill with Toyota WS ATF only, and check the level at the overflow plug with the fluid at operating temperature. Clear codes and reset learned values with a scan tool, then road test with light and moderate throttle shifts so the computer can relearn. If the SLU solenoid on your old unit was the subject of codes, a new A750 TCC solenoid is inexpensive insurance. On a high-mileage unit with worn clutches, the A750E overhaul kit may be the better repair.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
4WD trucks use the A750F, not the A750E. The valve bodies are closely related, but confirm with your casting numbers or send us your VIN before ordering.
No. The Tacoma switched to a six-speed automatic with the 2016 redesign. For other 2006-2018 A750E vehicles, send your VIN and we will confirm.
It can if the TCC relay valve or lockup bores are worn. P2757 can also come from degraded WS fluid or a weak SLU solenoid, so check the fluid first.
Toyota genuine WS ATF. Do not use Dexron or a universal multi-vehicle fluid in this transmission.
Yes. Clear the codes and reset learned values with a Toyota-capable scan tool, then road test with several shift cycles.
