No problem. Post up. Post pics. We will be here.Hey guys, just wanted to say thank you for your advice and input; with apologies for a little dose of OSU/Michigan rivalry that I couldn't resist. We'll have to decide what to do next but your inputs help immeasurably. Thanks again!
It sounds like you've got a good amount of replies. Instead of telling you what "will" happen, I'll give you my story. Exactly what you went thru, my car went thru at maybe 5,000-10,000 mile mark, basically brand new. Whining, highway overheating, limp mode, etc. I was almost killed multiple times in my car because of the CVT. I then refilled to EXACTLY between the dipstick fill lines "hot" and completely eliminated that problems I was having. I attributed it to a factory underfill/overfill condition which causes massive havoc on oil foaming and oil pump cavitation. This same condition can happen on higher mileage CVT due to transmission case oil leakage. I've heard the CVT oil will degrade the silicon gasketing material, I would tend to believe it. I run Loctite 518 on my CVT rebuild/upgrade, which is completely impervious to CVT fluid. External coolers help and there are many threads on that subject, but proper fluid fill is much much more critical IMHO. A correctly filled CVT oil sump level will be whisper quiet, this is so important to the oil pump function and how it supplies hydraulic fluid to the valvebody control unit that it isn't stressed enough.Hello all, new member here. I searched the site for this issue but didn't really find a thread that was quite on point for what we experienced recently. We were making a roughly 350 mile trip on the interstate and we experienced pretty much a total loss of power on the freeway. Outdoor temperatures were probably in the mid-to-upper 80's; so its not like we were cruising through Death Valley. We went from 85 to 50 almost immediately and continued to slow almost to the point of getting rear ended. You could pin the accelerator pedal to the floor but all you would get is increased engine rpm and the car would continue to slow down. So we hopped off (well, limped off actually) at the nearest exit and waited for 20 minutes or so and proceeded in hopes that cooling it down would help; which it did for a while. Later we had to pull off again and wait it out a couple more times. The first interval was around 150 miles or so...second was around 80 miles. Similar threads seem to point to a TCM component that is designed to protect the transmission from overheating damage. So, I'm wondering if this was actually transmission "slippage" or the car flipping into "limp mode"; which would beg the question of why was it getting hot enough to go into protection mode? This leads me to wonder if I need to install a tranny oil cooler?
Other commentary suggests that a CVT fluid change may correct the problem...or at least what sounded like similar problems. Any chance this is related to a bit of over-due maintenance??
We purchased the car used so are not sure of its maintenance history. However, we do know that its bone stock with no tweaks to turbo boost, transmission performance, etc. Just a nice little stock Juke with about 110K miles on the clock.
As I mentioned, I did try to search for something that seemed to fit our situation but didn't come across a good match in previous threads. So, if I could ask for your input, it would be very much appreciated.
