Ah crap. My transmission is doing something hard to explain. At least, I feel like it's the trans.
2014 6 touring with AT and 120,000.
trans filter/fluid change at 75,000 (planned on keeping it for another 5+ years)
I'm not a grandpa driver. A lot of stop and go in Chicago and I have a semi-serious road rage condition. Self diagnosed, of course...
symptoms:
When I accelerate, and the car downshifts automatically and it jerks/thumps. It's very sporadic and if I baby it, no problem. By baby, I mean take 20-30 seconds to get up to 60 MPH and no heavy acceleration. Sometimes I can accelerate WOT from a stop and it's no problem. Other times WOT acceleration results in the thump/clunk and then the car goes into low power mode and the check engine and traction control lights come on. The dummy lights stay on until I stop the car and turn it off. At which time I start the car and resume driving as normal, albeit much more gently.
I'm carrying my fault code reader with me in hopes that i get a convenient opportunity to pull the trouble codes but the few times they have come on, I haven't been in a situation where it was safe to stop for a period time and fumble with the code reader. Even though I changed my fluid and filter at 75k, I'm going to do it again Saturday. I'll also change plugs, air and oil/filters, etc. if I'm working on the car, I'll do everything. If, after I change everything, it still continues, I'll force it into giving the code. The symptoms are getting more frequent so if filter/fluid change doesn't work, reading the codes shouldn't be a problem. I did check the fluid level and it was spot on.
I hope I'm missing something easy here and someone reads this and the light bulb goes off but if that's not the case, has anyone replaced their transmission by themselves? Have you done it by pulling the engine out of the top? I have the equipment to do that, but I don't have a hoist so I can't lift the car up off the engine. If it is a bad trans, I would want to buy a used one off ebay and swap.
As always, I appreciate all of your input. i don't post often but i do get a lot of valuable from the community so thanks in advance.
