PrimeTime Posted May 1, 2012 Report Share Posted May 1, 2012 I'm the new guy on the forum so I will get right to it. My 2000 S70T5 has recently been experiencing some rather weird and intermittent transmission shifting symptoms. When first started and driven, the trans shifts perfectly and continues to do so for the first 30 minutes or so of urban driving. Gradually, the downshifts start exhibiting symptoms as if the trans is deliberately trying to remain in a higher gear for much too long which sometimes results in bogging down the drivetrain. It has never actually stalled the engine but it does make for a less-than pleasant driving experience. Even the upshifts occur too rapidly (meaning that it tends to find a higher gear far too early for the engine's RPMs). My gut feeling is that the transmission itself is probably not defective as it performs very strongly when cold and never slips. I am wondering if this might be something like a defective solenoid or electronic control module. I even did a recent trans fluid change to see if that might help matters but that seemed to be in vain. At least the old fluid was clean and new looking with no trace of debris nor did it appear to have been burnt. Am I alone with this or has anyone else had similar issues with a similar car?
