2004 STR Transmission issues
Hello everyone
I have a 2004 STR which had leaking transmission lines,sleeve and pan gasket.These were all replaced along with new ZF fluid.I also changed the diff fluid with Royal Purple synthetic(same grade recommended by jag).
The car had the surging problem between 40-60km/hr and took a long time to go into 6th gear on the highway.I had the car's transmission reprogrammed by jag which helped for a while.The surging cam back.I then took the car to my local mechanic who cleared a code between traction control and transmission.
The surging has gone away,however, the transmission still takes along time to go into 6th.Oddly enough,whenever I take the sport button off and push it back on the trans shifts into 6th gear immediately.
My trans guys says this is not being caused by the transmission and believes something else is causing the issue.
Does anyone have any thoughts?
Thanks in advance.
