A750F Solenoid Kit 2002-2016, remanufactured and ready to install. Fits the A750F. Ships fast from the USA.
This remanufactured solenoid kit is for the four-wheel-drive A750F five-speed used across the 2002-2016 window, the transmission behind the V6 and V8 in 4x4 versions of the Toyota 4Runner, Tacoma, Tundra, FJ Cruiser and Sequoia and in the Lexus GX470. Owners usually find it after searching for an A750F that shifts erratically, holds one gear in limp mode, engages hard, or keeps setting shift solenoid performance codes. The kit is listed with an A750E reference because the two transmissions share the same valve body family; the F suffix marks the 4WD version with the transfer case behind it.
Inside the A750F there are no mechanical shift controls. The transmission computer reads vehicle speed, throttle and fluid temperature, then energizes the solenoids on the valve body to move shift valves and regulate line and clutch apply pressure. Oil reaching the solenoids passes through a solenoid modulator valve that limits their feed pressure. When the solenoids themselves wear, they stop delivering the pressure the computer asks for. On a 4x4 that tows, crawls in low range or works in heat, that wear shows up sooner because the fluid runs hotter for longer.
Start with codes, fluid level and fluid condition. Hot, burnt fluid points toward clutch damage, and our guide on Aisin slipping under load explains how to tell a hydraulic slip from a control fault. Next, test each solenoid circuit at the case connector and look over the internal harness. Then think about the valve body. TransGo notes that a worn solenoid modulator valve bore on the A750 limits the pressure feeding the solenoids, which produces solenoid and TCC performance codes that new solenoids alone will not clear. If your truck has high miles and those codes return after a reset, plan for a replacement A750E/F valve body or a valve body repair along with this kit. For general shift-timing complaints, Aisin harsh or delayed shifts lays out the order of checks.
This kit is listed for the A750F from 2002 through 2016. Over that span Toyota revised the transmission and its harness, so the solenoid connectors and valve body details are not identical on every truck. Before draining fluid, compare the solenoids on your valve body with the kit, or send us your year, model and VIN and we will confirm the match. If you have a 2WD truck with the A750E, the matching A750E solenoid kit for 2002-2016 is the one to order. All of our A750 parts are in the Aisin transmission collection.
Plan on a pan-off job with the transmission left in place; on a 4x4 you may need to drop a skid plate first. Drain the fluid, remove the pan and filter, mark and unplug each connector, then remove the solenoid retainers. Lubricate each new O-ring with ATF and push the solenoids in straight. Do not overtighten the retainer bolts in the aluminum valve body.
If the inspection turns up burnt clutches, step up to a rebuild such as the A750E/A750F master rebuild kit and install the solenoids during the overhaul.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The A750F is the four-wheel-drive version and the A750E is the two-wheel-drive version of the same five-speed. This listing is for the A750F and carries an A750E reference; confirm the connectors and solenoid count on your valve body before installing.
It is listed for that range, but the transmission and harness changed over the years. Compare your solenoids with the kit, or send us your year, model and VIN to confirm.
If the solenoids are the cause, yes. If the solenoid modulator valve bore in the valve body is worn, feed pressure to the solenoids stays low and the codes can return, so the valve body needs attention too.
Toyota WS automatic transmission fluid. Check the level at the overflow plug at the fluid temperature Toyota specifies.
A filter and pan gasket every time, and the internal harness if its insulation is cracked or brittle. On a high-mileage unit with burnt fluid, a full rebuild kit is the better investment.
