Hey Scotty,
I've got a 2008 Mazda 3 sedan, 2.0l naturally aspirated, tiptronic automatic trany, bone stock with 144k miles. Currently no codes.
The other day while in stop and go traffic, from a stop I gave it gas and the car didn't budge. Rpms went up but car wouldn't move. Check engine light popped on and engine was still on. I through it in park turned it off and back on and everything was fine, check engine light went off. I plugged the scanner in when I got home but it had no codes. Also, I've noticed a loss of power while hitting inclines. Could this be related? Please advise, thanks for what you do!
When and how often has the transmission fluid and filter been changed in 144K miles?
I changed the fluid at 60k and 120k. Filter though, I'm about to look into
A generic OBD2 scan tool is not sufficient to diagnose transmission problems. Chances are your transmission is shot, but check fluid level and condition. If it's low try adding fluid and see if the car will move. (If the transmission has never been serviced for the last 15 years and 144k miles though it's likely toast.)
Fluid level is good and it's clean. Should I drop the pan and look for shavings?
Probably not a bad idea to check for anything bad in the pan. However a fancy bidirectional scan tool is really needed to do a proper diagnosis on electronically-controlled transmissions.
The fluid may look clean but if the filter wasn't changed along with the fluid, it's like changing your engine oil without changing the filter, not good.
Good point, if the filter is badly clogged that could definitely be causing problems.
Got it, so I'm definitely changing the filter then getting it scanned
