Its simple, rugged design made it a favorite for trail riding, farm work, and even daily driving in rural areas.

Common Transmissionon Emites

Te transmissionon in a Jeep CJ- 5 is a robutt but aging assembly. Depending on thee model year, you may find a Dana 18 transfer case pairod with a T- 90, T- 150, or T- 176 three-speed, or a T- 177 or T- 178 four- speed. Later models sometimes came with thee SR- 4 or thee stronger T- 5. All of these ce can suffer from similaar problemwhein nessected.

Slipping gears occur when he transmissionon faices to stay engaged under load, often akompaniate by a sudden rise in engine RPM without corresponding acceleration. In thee CJ- 5, slipping can em frem several root causes:
