The family of 4-speed automatic transmissions "TorqueFlite" - A518/ A618 has been installed on rear-driven Dodge and Jeep with engines capacity about 6 liters (for A618 up to 8 liters) since 1990. This transmission is based on design of its predecessor А500.

Technical issues and repair guidelines

Filters for these automatic gearboxes are one-time-use with a felt membrane. With the mileage higher than 100 thousand kilometers, it is recommended to change filters with ATF. These transmissions are not very sensitive to oil type and its level, but with age oil cleanness has a greater significance for this transmission.In addition to the filter, specialists order the repair kit of gaskets and seals for the overhaul. In most cases, friction components are not ordered separately (if the oil has burning smell), but as a whole kit of frictions, which vary in years of manufacture. The kit of steel discs is ordered as well.The complete kit of spare parts Masterkit is ordered in roughly half the cases.

Popular parts to be repaired in A518/ A618:

• Friction clutches and steel discs Direct and Forward operate more intensively than others and as a result get burnt. Frictions penetrated with burnt oil from the discs should be replaced.
• The brake band (Reverse) is a spare part and should be replaced as often as the kit of friction componens. The list of spare parts also includes plastic discs-washers.

The electric part of the transmission exhausts its resource because of operation in overheated and contaminated ATF. Basically, controlling problems occur in the torque converter lock-up solenoid because of hot and contaminated ATF.
