Purchased 2017 mazda3 touring (2.0 L) - a private sale that was offering good price - so I overlooked a few signs. With a little over 100K miles on the clock, i knew i will need to deal with some unknowns…well, long story short, started noticing 2 things:
1. A thump/clunk sound when driving over pot holes. My first instinct was bad struts, as shocks seem fairly firm.
2. a little hard shift going from 3rd to 4th gear (automatic transmission).
Took it to mechanic, and they diagnosed that it was actually the engine and motor mounts that were bad instead of struts. Ans also, they could not find transmission throwing any error codes, so attributed that hard shifting to the mounts.
I got the job done…that took care of thump/clunk sound but i still feel a little jerk when i put the car from P to R. Also the hard shifting issue is still there.
The technician thinks that the problem is with the EMU programming. The shift points are not properly set. But since he could not do it, he is referring to a dealership.
any insight or recommended diagnostic approach will be highly appreciated. Also, is there no way to have mazda “unlearn” and “re-learn” the shift mapping without going through the dealership route?
