A340E Master Rebuild Kit 1988-98, new and ready to install. Fits the A340E. Ships fast from the USA.
This master rebuild kit is for the early, cable-controlled generation of the Toyota A340E and its four-wheel-drive twin, the A340F. If you own a 1989-1998 4Runner, a 1988-1992 Cressida or an automatic Supra from that era and the transmission slips, flares into overdrive, or has filled the pan with clutch material, this is the parts set for a complete overhaul. The kit in the photo carries a full set of friction plates and steel plates, two valve body gasket sheets, the pan gasket, front and rear lip seals, thrust washers and the piston and sealing-ring O-rings, so the unit goes back together with every wear item new.
The A340E is a four-speed rear-drive automatic: a three-speed planetary section with an overdrive planetary in front of it. Clutch packs and brakes hold each planetary member, and the valve body applies them with line pressure. On these early units throttle pressure still comes from a TV cable at the throttle body, while the computer handles shift timing with two shift solenoids and an on/off lock-up solenoid. GEARS magazine notes Toyota kept that layout for about 15 years, until the 2000 model year dropped the cable for an electronic SLT solenoid. That matters to you because a 1988-98 overhaul is only right when the TV cable is adjusted correctly afterward; new clutches will burn quickly on low line pressure.
GEARS magazine lists a bad throttle position sensor as one of the most common A340 complaints, and a faulty TPS or misadjusted TV cable can make a healthy transmission shift late, harsh or soft. Check the TV cable stop, the TPS signal and the shift solenoid circuits before tearing the unit down. Our guide to Aisin transmissions slipping under load covers the pressure and road tests, and shift flare vs slip explains how to tell a timing problem from a worn pack. If the fluid is burnt and the slip shows up in a gear regardless of throttle, the clutches are done and this kit is the fix.
The listing names 1989-2004 Toyota 4Runner (2.4L, 2.7L, 3.0L V6, 3.4L and 4.0L), 1988-1992 Cressida, 1988-1998 Supra 3.0L and the 3.0L Crown. It covers both the A340E (two-wheel drive) and the A340F (four-wheel drive with transfer case). Two cautions: the twin-turbo 2JZ-GTE cars used a heavy-duty A340E version with internal changes and a different case, and 2000-and-later units changed the valve body, so match the identification on your case and valve body before ordering. Send us your year and VIN if you want us to check, or see every Aisin part we carry on the Aisin transmission page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes. The listing references A340E and A340F. The F version is the four-wheel-drive unit that bolts to a transfer case; the clutch and seal set inside the main case is the same family.
Check first. The twin-turbo 2JZ-GTE cars used a heavy-duty A340E version with internal changes. Send us your VIN before ordering for a turbo car.
No filter appears in the kit photo. Plan on a separate filter, such as our A340 solenoid and filter kit.
Follow the owner's manual or dipstick marking for your year. Many 1988-98 trucks specified Dexron-type ATF, while later Toyota units specify Type T-IV. Capacity is a little over 8 liters total.
Yes. These units use a throttle valve cable, and it must be set correctly or line pressure will be wrong and the new clutches can slip and burn.
It is listed for 1988-98 applications and the 4Runner. Later trucks with the V8 use an updated valve body and a different gasket layout, so match your unit before ordering.
