aggie107 Posted November 26, 2003 Share Posted November 26, 2003 My 1999 ES 300 has started having shifting hesitation issues. My car has 63,000 miles and seems to run very well except recently it seems to hesitate shifting into high gear when the car is cold. Does anyone have any suggestions or ideas?

ProZac Posted November 27, 2003 Share Posted November 27, 2003 aggie, Where do you live? Because Cold for southern California (where i live) is 55F. I have a 97' and haven't had too many shift hesitation when i start up the car (i have almost 75k miles). Does it keep happening on cold startups, or does it only happen when it is REALLY cold outside? ~Brian~ Quote Link to comment Share on other sites More sharing options...
amf1932 Posted November 27, 2003 Share Posted November 27, 2003 seems to hesitate shifting into high gear when the car is cold This is a normal situation by design. The upshifts are delayed until the engine reaches a predetermined temperature. This is established by the ECM. Quote Link to comment Share on other sites More sharing options...
