4EAT Modifications

NUMBER: 16-58-94
DATE: 03-08-94

The following modifications have been made to the 4EAT transmission to enhance its operation and durability. It is recommended that whenever an early 4EAT assembly is being repaired or rebuilt that these new components be installed.

This Bulletin is meant to assist you in diagnosing some symptoms, identifying updated components and locating related repair information.

1. Oil Pump Gasket - Refer to Figure 1

The transmission Oil Pump Gasket (P/N 31339AA121) was changed to a metal type gasket to lessen the possibility of gasket deterioration. This gasket was installed in production starting with transmission number 513102/SVX, 527022/Legacy, and since the beginning of production on all Imprezas. This gasket must always be used when gasket replacement is necessary. When using this gasket, the small metal deflector mounted to one of the oil pump cover bolts must be removed (Reference Parts Bulletin PT-26-03-93).

Symptoms of a deteriorated gasket are approximately 1/2 line pressure at idle and full line pressure at stall speed. It may also be accompanied by a delay going into reverse on SVX and Turbo vehicles.

2. Transmission Case - Refer to Figure 2

The transmission case was slightly modified starting with transmission number 426208. Modification was made to prevent oil pump gasket deterioration. Installation of the updated oil pump gasket is all that is necessary to prevent gasket deterioration on these earlier transmission.


Symptoms are the same as with oil pump gasket deterioration in Number 1 above since it will result in a gasket sealing problem. In both cases, oil pressure will be degraded. Other related symptoms may be a delay in starting when the select lever is placed into "D" and/or "R" from neutral or park.

3. High Clutch Seizure/Failure - Refer to Figure 3

Numerous modifications have been made to the high clutch and related components as listed below. Modifications were done to ensure adequate oil flow to components for cooling purposes. Some models will only need a few parts to bring them up-to-date while others will need more.

Legacy N.A. - Install Thrust Bearing (P/N 80653620) only up to transmission number 351299. The diameter of this bearing has been reduced from 52 mm to 50 mm to ensure adequate lubrication to the high clutch assembly.

SVX and Legacy Turbo - Install High Clutch Drum (P/N 31541AA030), Reverse Clutch Fiber Plates (P/N 31532AA080), Reverse Clutch Steel Plates (P/N 31536AA100) and one of the following selective Plates (P/N 31567AA350-390) up to transmission number 463969. Due to design changes between the original parts and the updated ones, these components must be replaced as a set.


Install High Clutch Hub (P/N 31550AA020) and Thrust Bearing (P/N 806537010) only on SVX and Legacy Turbo models up to transmission number 633657 for SVX and transmission number 615173 for Legacy Turbo models.

The modified high clutch hub has additional lubrication holes in it to provide required lubrication to the fifth clutch plate of the high clutch assembly. Recommended repair for a failed high clutch is replacement with the modified part(s) as applicable above.

Symptoms of a failed high clutch might be no shifting or an increase in engine rpm when shifting into 3rd gear (trans. neutrals out)

4. Transfer Clutch Driven Plates (Metal) and Seal Rings - Refer to Figure 4

Betamethasone dipropionate aug 0.05 ointment

Betamethasone ointment It is a combined drug with a fixed solution of dosages of active substances -lisinopril and amlodipine. The first one is a blocker of the enzyme peptidyl. The second hormone activates the discharge of aldosterone by the cortex. ACE restriction leads to reduced absorption of angiotensin. Since the mechanism is based on the inhibition of the aldosterone and chemosin systems. The pill reduces an arterial pressure in people with high tension as well. buy an anesthetic cream for pain. It contains both pain relieving and relaxant herbs. You also want some cream with vitamin B to prevent your joints, ligaments and other body tissues from inflating. To prevent a bad infection in your joint, you may also want to try taking ibuprofen, because it helps to block the pain-generating hormones that make you more likely to tear tissues. Ibuprofen blocks both prostaglandin E1 and E2, so it can ease pain.
