Hey Kevin I know this is a few months old and you probably have resolved the issue but I figured I would share my recent experience with a GMC Acadia. Customer of mine has Transmission Hot Idle engine message come up so they went to a Big O tire and Big O recommended a transmission flush. They declined the work and brought it to me instead. I checked the fluid and it was full but discolored. I Test drove the vehicle with a scanner attached to check transmission fluid temperature and on a slight incline at 70-75 mph the transmission temp kept rising and got to 240 degrees I also notice a delayed shift or shift flare between several gears. I came back to the shop and double checked the fluid and noticed it was above the max line and if I wiped the wire portion of the dipstick the fluid was actually way overfull. I flushed the transmission and then drain almost 4 quarts of extra fluid out of the transmission. I then took the same test drive route after warming up the transmission and the fluid temp only got up to 200 degrees and the shifting issues were resolved. The fluid when overfull gets air bubbles in it and the air bubbles reduce the effectiveness of the transmission cooler and creates delayed shifts.Hey everyone. Just bought a used 2016 Traverse AWD a few months ago. It now has a little over 50k miles. I notice that it stays in lower gears longer than it should around town. When I drove it on a long trip (over 600 miles) and after about an hour of driving I notice it doesn't like to shift into 6th gear; just stays in 5th. After a few hours of that the display told me "trans is too hot, idle engine". So something is wrong there.
I decided to change out the ATF since it was due I guess. When I drained the fluid, a little over 9 quarts drained out. That seems odd since I expected 4-5 qts reading through this forum. Is that possible something new with 2016 model year or is there something odd going on in my powertrain? According to the Amsoil website the full ATF fill is 9.5 qts. I don't think there would be an extra 4-5 qts left in there after over 9 came out. Any suggestions?
Regular Dex is about $6/qt and the full syn was over $12/qtI believe regular Dexron VI is a synthetic blend.
If youre going to do several drain and refills to clean up the fluid, I would get the one on sale.
If youre going to drain/refill and then leave it alone for many many miles-- I would go with full Syn.
What prices are you seeing?
Quick question, does it take that long or that many miles for the new fluid to completely circulate through the torque converter, cooler lines, etc... or would I be good driving it say 50 miles & then do my second drain & fill again in a day or two? Much obliged sirjust for comparison...
the 1st drain- new fluid vs 50K fluid.
and the 2nd drain about 420 miles later- new fluid vs mixture of old+5qts new.
I did my Spark Plugs at 100,000.Next jobs to tackle are spark plug changes, coolant flush, power steering flush, brake lines flushed, & replacing drive belt; all of which have never been done yet. My goal is to switch all the fluids over to Amsoil fluids.
I have the towing package on mine. My temp runs at 160 on the dash. I also have heavy-duty coolingJudging by the color of the transmission fluid that people have had come out of their Traverse, I would say 50k mile change is a wise decision. These transmissions run fairly hot, even with the tow package, they easily get up over 210*F in heavy traffic. Most pickup trucks run around 150 to 170*F, so 200-210*F+ seems pretty high to me.
That being said, I did not do a UOA, so maybe my fluid was okay.
