I left for work and it was upper 60's out and I didn't let it run more than 30 seconds before I took off. It shifted hard all the way to work (approx 11 miles). Instead of the normal smooth and barely noticeable shifts they were apparent but not horribly jerky. I made it to work and went inside for 15 min or so and came out and got in it and went to the bank and it was just like normal. All the way home it was fine. It has never done that before to the best of my knowledge. Am I a little worried for nothing or do I have good reason to be slightly concerned????

Almost 88,000 miles on her.

Lol, mine just did that, and I was about to ask the same queston.....sorry for the no help. But were in the same boat.

you need to let it warm up before you go off...dont get in and roll...and how many miles do you have and has it had its 100x mile tune-up??

well just keep an eye out for posts on my thread

oh yea nvm on the mileage

How long should I let it warm up, i've just got in and left many times before and never had this happen. even when it was colder that I described. If you read my whole post I put how many miles it has because I knew that would be a question. i got the car with 80,000 and right after I got it I took it to have the trans fluid flushed and a new trans filter and yes they did it right not just drop the pan and let the oil drain out and fill it back up. Is there something else I should have done?

You probably should not have had the trans flushed with the amount of miles it had on it. There's a history of trans failure with higher mileage trannies that have been flushed after never being serviced like that before. It dislodges any particles like metal shavings or the like that have stuck to the internal parts, which leaves them free to wreak havoc on the inside of the tranny.

Not saying there's a cause for alarm, but you really should have only changed the fluid. You may not have hurt it, a one-time circumstance like this really isn't much to worry about, especially since you said it wasn't really bad and nothing was slipping.

Food for thought.

Edit: Oh, also, if you have done any 'spirited' driving lately, the PCM is constantly learning and adjusting to your driving habits so that may have contributed. At any rate, we can't really tell you much.

Check the tranny fluid for discoloration, burnt smell, any particles stuck to the dipstick, etc.

Well i did get on it a bit a couple times the day before which is contrary to what I normally do. So may be it did change something and when I didn't get on it again it learned its self back, I dunno in any rate I just wanted to put this out there to see if anyone else had it happen or maybe help someone else. Thanks for the info though.

[If you read my whole post I put how many miles it has because I knew that would be a question.]

which is why I posted what I said...

[oh yea nvm on the mileage]

yeah sorry. i wrote that before i saw your correction. i just hate it when people don't read all of the post and comment. no prob man, thanks for the info.

Like Arcxnus said, it is bad to do a complete flush on a high millage tranny. A simple fluid and filter change will be whats best for your tranny. Is the car still doing it, or was it just a one time thing?
