Title: Shifting into overdrive too soon?
Post by: Elpresidente on November 08, 2012, 10:45:50 am

My 700R4 shifts into overdrive at about 35MPH just cruising around town at light throttle. The trans was rebuilt, and I noticed before it was rebuilt it wouldn't shift into OD until about 45MPH at cruise. Is this shifting too early, and possibly hurting my trans/fuel economy because the engine has to work a bit harder?
Just my thoughts.

This sounds normal to me.
