Yes. All transmissions eventually have problems. Have a transmission shop diagnose yours.

They sure do. There's a shaft in the transmission that wasn't hardened at the factory. The splines break off and you lose overdrive and TCC lock in. At 70,000 miles you're right there at the failure point. A reputable transmission shop can fix it. Hope that helps! Jim
