Thank you for any help provided.
If you're religious, I recommend prayer.
Seriously, though, at 115K miles, maintenance is VERY tricky. An old-school mechanic who saw his hayday in the 70's once told me NEVER to change old transmission fluid, or it would wreck the trans immediately. Now, being the smart, college educated 20-somthing I was, I knew everything, and that man didn't have a clue about these here new transmissions. So I took my Infiniti to the dealer with 110 on the odo, and they changed filters and fluid for me. Not 5K miles later, the tq converter had multiple failure codes, the transmission wouldn't shift, there were engine/driveline rpm incompatibility codes, on and on and on, and I bought a new transmission and developed a new found respect for EXPERIENCE vs. BOOKS.
So you can see, maybe there is more to it than checking the box "Got new fluid!".
In my 2010 WK, I replaced the trans fluid at 68K miles, which was 8K over the factory recommended, but also a few years past due, likely. Anyway, I DID note that the transmission shifted very funny afterwards for about 5k miles. It made me very nervous. In the end, I dumped my Jeep because of this, and other issues, but I do feel that the transmission had to "re-learn" how to shift after that fluid change.
A friend of mine at the Dodge dealership, who I have known for a long time and view as a vehicle savant when it comes to doing work on them (the guy really is an artist when it comes to modding and repairing vehicles.) told me to change the fluid every 30K if I wanted that vehicle to REALLY last. Based on my two experiences above...I strongly agree.
So, if you have bought used and don't know if it was changed or not, or if you know it hasn't...do you feel lucky?
