A750E Banner Rebuild Kit 2003, new and ready to install. Fits the A750E. Ships fast from the USA.
The 2003 model year was the first for the A750E, the five-speed automatic Toyota put behind the 4.7 V8 in the two-wheel-drive 4Runner. Twenty-plus years on, many of these trucks are showing the same thing: a flare between gears when the engine is working, a slow or soft pick-up into drive, and fluid that smells cooked. This banner rebuild kit is the soft-parts package for that job. It brings a complete overhaul gasket and seal set, a set of friction plates, the bonded pistons and a new filter, which is what a shop needs to renew every clutch pack in the case without paying for a full master kit.
The A750E shifts its five ratios by clamping clutch packs and brakes with hydraulic pistons. The valve body routes line pressure to each piston, the piston squeezes frictions against steel plates, and the drum or planetary member locks. Two things wear out with age and heat: the friction material glazes and thins, and the rubber on the pistons and seals hardens so it stops holding pressure. Either one lets the pack slip, and slipping generates more heat. A banner kit replaces both halves of that problem at once. The frictions in this kit are Allomatic, and the gasket and seal portion is a Toledo or Precision overhaul kit, depending on what is in stock when it ships.
Pull the check plug and look at the fluid, then scan for codes. Our ATF color and smell chart helps you read what comes out. Clean fluid with a single solenoid code usually means the fault is electrical or in the valve body, not the clutches, and a A750E solenoid kit or valve work may be the cheaper fix. Burnt fluid and a slip you can feel on a road test mean the packs are finished. If the slip only shows up under load, read Aisin slipping under load first, because a worn line pressure boost valve can cook a new set of frictions just as fast as it cooked the old ones.
This listing is for the 2003 A750E, the electronically controlled two-wheel-drive version. In 2003 that means the rear-drive 4Runner with the V8; the four-wheel-drive 4Runner, GX470 and Land Cruiser of the same year use the A750F, which has its own A750F 2003 banner kit page. The kit is made for 2003-up A750 units, but Toyota made running changes over the years, so read the transmission code on the case and compare clutch counts per drum before you tear the unit down. If you are not sure, send us your year and VIN and we will check it. The rest of the parts for this family are on our Aisin transmission parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
In 2003 the A750E was used in the two-wheel-drive Toyota 4Runner with the 4.7 V8. Four-wheel-drive 4Runners, the Lexus GX470 and LX470, and the Land Cruiser that year use the A750F. Check the code on your transmission case to be sure.
An overhaul gasket and seal set (Toledo or Precision), Allomatic friction plates, the bonded pistons and a filter. Steel plates, drums, bushings, planetaries, solenoids and the valve body are not included.
A banner kit covers the gaskets, seals, frictions, pistons and filter. A master kit usually adds steel plates and sometimes bushings. If your steels are clean and flat, the banner kit covers the parts that wear out.
Not always. Slip only under load can come from low line pressure caused by valve body wear. If the fluid is clean, look at the valve body first. If it is burnt with debris, the frictions are gone and they need replacing.
Fill with Toyota WS ATF, check the level hot at the check plug with the engine idling, and reset the transmission adaptive values with a scan tool after the rebuild.
