I was finally able to pick up the Quest on Thursday, about noon with a Nissan rebuilt transmission installed. For the record, I dropped it off on Wednesday, 6/1. and picked it up on Thursday, 6/9. It only took a day and a half to install it.
To answer palmerWMD's question, it had symptoms and I didn't know it. Remember, I've only had the vehicle since September. Now that I have a good transmission, the first thing I noticed that, when stopped and in D or R, if I do not press the brake, it will creep. It didn't do that before.
After picking it up, I shot straight to the nearest I-40 West on ramp and headed west. That is, after making sure the cvtz50 was getting good readings. Here's some observations:
The speed limit on this section of I-40 is 75. If I tried to maintain that speed, the temp would climb, eventually into the orange, 198+. If I dropped speed to about 65, it would drop to about 176-180. Keep in mind the ambient temp was hovering around 100, maybe more.
When in Western Arizona, it was midafternoon and the ambient temps were 105-110. Each time there was a grade to climb, the temp would go up into the orange. I would shut off the AC and drop speed to 60 and it would go back down. It did this at least 1/2 dozen times.
I have always wondered why a Quest with < 40k miles would have the (can't remember) code and jutter. I think maybe I discovered why. According to CarFax, this Quest spent its first 6 years in Texas, New Mexico and Arizona. Hot climates with fast speed limits. I'm guessing it was driven hot and fast and without knowing it (no cvtz50), the drivers were cooking the transmission. So, those of you in these states, you may want to think twice about hitting 75-80 on a hot day. I wonder how many CVTs died just for this reason.
BTW: Is there a break in period for these trannies? If there is, I probably did not follow it. I put in 450 miles that first day. Flagstaff, AZ to Tehachapi, CA.
