No problems with this transmission so far but it does shift harder when temperatures are below freezing. At 21,000 miles I had oil analysis done on both new and the PF factory fill Matic-J and found that the high temp 100 C viscosity had sheared from 7.3 to 6.5 cSt's or about 11%. When I talked with the local service manager about it he requested from Nissan the maximum allowable ATF shear percentage but got no information from them on that.NVSteve wrote:This will be my third winter with the PF. The first winter was fine, but last winter I kept experiencing the same thing over and over: when driving off to work with everything cold, the transmission would make a lurch from 2nd to 3rd. Kind of like someone was towing you around with a rope, then yanked on it hard & fast. It only happens between those 2 gears, and only when temps are 40F & below. I've noticed it a lot the last 3 weeks or so, and even brought it up 2 weeks ago at my last dealer servicing. They said to let it warm up, to which I replied "kiss my a$$," although not out loud.
I only shift from 2nd to 3rd twice on the way to my office, and by the time I'm just a couple miles from home, everything is nice and warm-no more shifting problems. If I completely granny it when doing the shift, it won't lurch, but then I'm also slowing down anyone who happens to be behind me.
Has anyone else experienced this? My fluid levels are fine, but I'm thinking I will ask the dealer if there are any other choices for transmission fluids.
Thanks, GB. I'll have to remember that next time I'm in for maintenance.Greybrick wrote: It would be interesting to know if changing the ATF from Matic-J to Matic-S fixes your problem.
