A245E Transmission Overhaul Seal and Gasket Kit for Corolla

This is the soft-parts overhaul kit for Toyota's A245E four-speed electronically controlled transaxle, the automatic used behind the 1.6L and 1.8L engines in the Corolla. It carries the rubber and paper you replace every time the case comes apart: both cork pan gaskets, the valve body and separator plate gaskets, the front pump seal, the two axle seals, clutch piston lip seals, the sealing rings and the full spread of case and valve body o-rings.

Fitment is Corolla 1.6L 1993-1997 and Corolla 1.8L 1993-2008 with the A245E. Check the tag on the case before you order - the same Corolla years were also built with the three-speed A131L and with manual transaxles, and none of these parts cross over. There are no friction or steel plates in this kit. If the clutch packs are burnt or worn to the backing, pair it with new frictions or step up to a master kit; if you are only resealing a unit that leaks or lost a piston seal, this is the box you need.

On the bench, lay the gaskets out against the old ones before you start stacking the valve body - the separator gaskets look alike and installing one upside down blocks a feed hole. Lube every lip seal with assembly gel or clean ATF, never install a piston dry, and air-check each clutch circuit after the pistons go back in so a rolled seal shows up now and not after the car is back on the road.

Typical reasons to reseal an A245E: ATF weeping from the axle seals or pump, a delayed engagement into drive that shows up after the car sits overnight, and a slipping shift traced to a hardened piston seal that bleeds apply pressure. Age-hardened rubber is the most common cause on these high-mileage Corollas.
