A340E Banner Rebuild Kit 1987-2001, new and ready to install. Fits the A340E. Ships fast from the USA.
A Toyota 4Runner, Tacoma, T100, Supra or Cressida with the A340E four-speed that now slips into overdrive, flares on the 2-3 shift or hesitates before it grabs Drive has usually run through its clutches and seals. This is the Precision International K88900K banner rebuild kit for 1987-2001 A340-family transmissions: an overhaul gasket and seal set packed with a set of friction clutch plates, which is what you need to put a tired A340E back together after teardown. The kit is listed for the A340E and the A340H.
The A340E is Aisin's rear-wheel-drive four-speed electronic automatic: a three-speed planetary section with a separate overdrive planetary unit up front. The computer picks gears by switching two shift solenoids on and off, and each gear is then held by hydraulically applied clutches and brakes. Those apply pistons rely on rubber seals and the rotating shafts rely on sealing rings; once either one leaks, the clutch sees low apply pressure, slips, and cooks its friction material. A banner kit addresses exactly that wear: new gaskets for the case, pump and valve body, new piston seals and rings so each pack sees full pressure, and fresh frictions so the packs can hold torque again.
Gears Magazine notes that this transmission commonly runs past 150,000 miles without trouble, and that the most common problems were a bad throttle position sensor and overdrive planetary issues. Both can feel like a worn transmission, so they are worth checking first.
Start with fluid level and condition and scan for codes. A shift solenoid fault can cause a no-reverse, 2nd-gear-start, no-4th complaint that looks mechanical; one documented 2002 Tacoma case stored P0755 for the S2 solenoid, and the real cause turned out to be a loose engine ground, not the transmission. Check that the throttle position sensor reads smoothly, then road test for a true slip. Our Aisin slipping under load guide and harsh or delayed shift walkthrough cover the order of checks on these units.
This listing covers A340E transmissions from 1987 through 2001; the kit is listed for the A340E and A340H. The family went into the 4Runner, Tacoma, T100, Supra and Cressida, along with Lexus applications. Be careful at the late end of the range: Gears Magazine explains that Toyota dropped the throttle cable and added an SLT pressure control solenoid starting with the 2000 full-size truck and its 4.7L V8, and Sonnax lists separate 2000-later A340E/F valve body types for V6 and V8 trucks. If you have a 2000 or 2001 truck, compare your old gaskets and the valve body to the kit, or look at our A340E banner kit for 2000-2009. When in doubt, send us your year and VIN before ordering. Everything we carry for this family is on the Aisin transmission parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
An overhaul gasket and seal set with a set of friction clutch plates. Steel plates, bushings, solenoids and hard parts are not part of this kit.
Possibly, but 2000-up trucks changed the valve body and pressure control. Compare your old gaskets to the kit or send us your year and VIN; the 2000-2009 banner kit may be the better match.
The A340F shares the main transmission section with the A340E. The kit is listed for the A340E and A340H, so confirm with your year and VIN before ordering for an A340F.
Use what your owner's manual or dipstick specifies. Earlier A340E units call for Dexron-type ATF and later ones for Toyota Type T-IV. Check the level hot.
It replaces the overdrive clutch frictions and seals, but also inspect the overdrive planetary and one-way clutch, since Gears Magazine lists overdrive planetary issues as a common A340 failure.
