fuganator Posted January 11, 2007 Report Share Posted January 11, 2007 I got my oil changed tonight and before i got it done, my tranny was shifting hard and working good. After the oil change, there was a noticeable difference in my tranny performance. There was not a hard shift from first to second and it didn't like WOT. Does anyone have any ideas of what may have caused this??? Quote Link to comment Share on other sites More sharing options...
Bowtie70SS Posted January 11, 2007 Report Share Posted January 11, 2007 Did you check the trans fluid? Where did you take it? Did you wait there, or did someone have a chance at a joyride? Dave Quote Link to comment Share on other sites More sharing options...
fuganator Posted January 11, 2007 Author Report Share Posted January 11, 2007 I checked the levels, they are fine. There was no chance for a joyride, I watched the whole thing. I took it to a local oil change place that has did it before. I usually do it but it is just to cold and my garage isn't heated. Quote Link to comment Share on other sites More sharing options...

fuganator Posted January 11, 2007 Author Report Share Posted January 11, 2007 The same, mobil 1 5-30 Quote Link to comment Share on other sites More sharing options...
PladdPezzPunk Posted January 11, 2007 Report Share Posted January 11, 2007 did they check the air filter. If they did i would take the mass airflow sensor off and clean it out with some CRC MAF sensor cleaner. Litttle bits of dust can make the sensor read wrong and the changes in airflow will affect how and when the tranny shifts. hope this helps.

fuganator Posted January 11, 2007 Author Report Share Posted January 11, 2007 Good to know, it might be coincidental, but if that tranny is going bad, that will be the third one in two years. I guess my next question would be, does anyone know of a good tranny shop in Minnesota? Quote Link to comment Share on other sites More sharing options...
oscareltemblo Posted January 13, 2007 Report Share Posted January 13, 2007 Did the old oil have any type of friction modifier? Quote Link to comment Share on other sites More sharing options...
AWDGM Posted January 16, 2007 Report Share Posted January 16, 2007 If they did a filter change, then it's probably the O-ring that goes on the filter outlet and into the valve body. I bet you'll find it's cut or damaged. Quote Link to comment Share on other sites More sharing options...
rivierakid55 Posted January 16, 2007 Report Share Posted January 16, 2007 how bout disconnecting the battery? wouldnt that cause the transmission to relearn? Quote Link to comment Share on other sites More sharing options...
