My car sometimes when shifting from 1st gear to second and then into third has a “harder” shift sound that I can feel under my feet.
It doesn’t do this all of the time. The garage said no codes showed and, of course, it didn’t happen when they test drove it.
My son-in-law suggested it might be worn transmission mounts. There is no vibration. The other day driving up a hill it was shifting in that manner and also seemed to “whine”.
Any ideas appreciated?
This sound and feel could be caused by a loose / worn mount. Sometimes the bolt inside the mount will separate internally and the increased slack will allow the transmission to twist and then snap back into place depending upon the torque applied.
