The family of 4-speed automatic transmissions
"TorqueFlite" - A518 / A618, has been mainly installed on the
rear-wheel drive trucks and vans produced by Dodge and Jeep since 1990. The A518
was modified to 46RH (retainer hydraulic) and later to 46RE (retainer
electronic), while A618 was updated to 47RE and 48RE. The A618 transmission is
considered to be a heavier-duty modification of A518. The driving torque of the
A618 transmission is equal to 610 Nm.

The design of the A518/A618 and 46RH / 46RE / 47RH / 47RE / 48RE transmissions is based on the same principle. All differences and modifications consist in the increased number of gears and addition of the torque converter and the block of solenoids.
Typical problems
Transmissions of this family were used by car
manufacturers for three decades thanks to their easy maintenance and resistance
to wear. Not complicated assembly of these transmissions simplifies their
repair process. Early transmissions of this family rarely require any repair.
The problem of spare parts replacement occurs in cars equipped with
transmissions, which have solenoids and the valve body. These transmission
components get out of order when the car mileage reaches 100 thousand
kilometers. Such breakdowns result in expansive repair services, because
damaged components should be replaced.
The most problematic areas in A518/A618:
- Central Support
- Retained (Governor) is usually rebuilt
- Direct Drum – exhausts its resource, but more
often this component burns out because of a long-time operation with
insufficient linear pressure
- Reverse Drum
- Frictional wheel-hub. Direct.
- The set of solenoids and sensors
Other seals, bushings, springs and bearings fail to function occasionally, due to peculiarities of the driving style and operation.
