Ok-I have read all the posts in the forum about all the transmission issues
with the rad etc... but I dont have a rad leaking issue.
I have a 2005 pathfinder with 114000 km on it and have had a shudder when I am at about 1500rpm or so.
Here is what I have found so far I had a tranny mechanic go for a test ride but could not duplicate the issue. I had checked the tranny fluid and noticed it was dirty. It was just black but had no milky look to it at all so I would assume rad fluid IS NOT leaking in the tranny
I knew it had to be changed thinking that would be the fix. I decided to put Amsoil synthetic in it which was not cheap but I think it it was the way to go. I also have synthetic in the engine. I still have the problem and when it happens I switch it out of overdrive and it stops right away.
It seems to happen when I am cruising at about 100 km then coast a bit-the rpms go a bit down to 1500 or so (between 60 and 80km/hr). As soon as I touch the gas to accelerate again it starts to shudder and vibrate. It almost feels like it is hunting to find the right gear. I try to keep it above 1500 rpm if I can but traffic does not allow me to all the time.
I am stumped as to what the real issue could be? Could it be an electronic issue? Is the tranny starting to pack it in?
Transmission Shudders in Overdrive
Moderator: volvite
Not a tech myself, but the "shudder" is the typical sign that the rad leaked into the fluid. I am willing to bet if you keep driving it that fluid will turn milky. I am guessing you are out of warranty, so my plan of action would be to do a flush on it asap and put a new Rad in it. You may be able to save yourself.
If its too late, then the only thing you wasted was the tranny flush because either way you will probably need the new radiator
PS if you want to try to replicate issue, drive about 45 mph, I thik thats about 80 km? which is right around where the torque convertor locks up, and that is where you will get your shudder.

Well
Turns out I was wrong. went to get my oil changed and checked the tranny & rad fluid. Both were red & milky. I wnt straight to the dealer where I bought it from.
They knew there was an issue with the rads and that Nissan had extended the warranty from 3 years to 5 years. Of course mine was up in April of this year. I started having issues before that of course. I am in the middle of talking directly with Nissan Canada although I am not expecting anything from them
The dealer said the rad needed to be changed & the tranny flushed 2- 3 times at a cost of around $ 1K. No guarantee that the tranny is hooped after this is replaced.
If Nissan does not do anything I suppose I will go for an aftermarket Rad and does the flush and see what happens there.
Nissan really screwed up on this big time.
I will keep this updated when I have more info.

Update
So I spoke to a few transmission guys here in town and they knew exactly what I was talking about before I even finished my story. I told Nissan my concerns and also e-mailed the dealer. I told them I was concerned about damage to the transmission and the answer the dealer had was-" We have had a few of these come in for repair and all we did was replace the rad and Flush the tranny and that it would be fine once all the milky stuff got out of there.
Anyways- I guess I stirred it up a bit so they are going to cover half of the cost to replace the Rad and flush a few times which should cost me around $600.00 or so. I bring it in on Weds before I go away on Vacation for 2 weeks and let them do their thing. If they find any evidence in the oil pan like filings etc.. then the tranny will be replaced but I have to pay half of that also-$2500 or so)
I am glad they helped me right away but at the same time I am still worried about any damage in the tranny with all the latex based back on some of the components. Latex does not mix with water very well.
I am crossing my fingers the rad change and flush will do the trick.

UPDATE
I left the Pathy with the Dealer while I was on vacation for 10 days. I just picked it up Monday and it surprisingly is running quite smoothly. The slipping issue seems to have disappeared. The dealer flushed the tranny 3 times and replaced the Rad and it only cost me $700.00. The whole bill was almost $2000.00. when they dropped the pan there was no metal debris so I cross my fingers that everything will be ok

This has me slightly worried myself. I have an 05 with 168k and I've started to notice a slight shudder when in overdrive.
I'm glad the dealer didn't fork you with that bill and covered a good bit of it. I'm tempted to try that bypass before this becomes an issue.
Markvk, where abouts in Canada are you from?

This post was what it took to get me to register. I just bought a 2007 Pathfinder in late May. I found all the info on the radiator after I bought it, but my mechanic said most manufacturers designed it that way. I notice a slight shudder when the transmission should downshift, but only at low rpms. I checked the fluid in the radiator tonight, crystal clear green. Is there any definite info on a potential recall?
I would check the tranny fluid and maybe change it to be safe. As soon as I noticed the issue I had I changed it and I think that saved me from a larger bill-(although it has only been a few weeks with the new rad)bkmtnff wrote:This post was what it took to get me to register.

I spoke to my salesguy who then left 3 days later. I had to deal with Nissan directly then, then called Morrey and I had Paul from service give me a call to explain what Nissan would help with. I did all the work sorting it out and they just fixed it. To be honest they did not really do me any favours but they did do a good job.Npath wrote:Markvk, I bought my Pathfinder from them too. Who did you speak with? I don't have the issue, but just in case...
UPDATE #3
The Pathy is going into the shop again on Monday for a test drive.
The transmission has been acting up. I just drove on the highway this afternoon and between 80-10km/hr there was a wicked shudder that even my passenger noticed that was very noticeable.
It happened about 2 or 3 times. As soon as I took my foot off the gas and accelerated again there was no problem. As long as I kept it around 100km/hr or higher it was fine-and of course it happens only in overdrive.
Also on the weekend I was coasting down quite a large hill and once I was at the bottom I pushed the gas and the engine revved up quite quickly then the tranny seemd to clunk into gear.
These issues are not constantly happening so I hope I can replicate the problems while the dealer has a look at it.
So they are going to take it for a drive and also check their diagnotic tool for any error codes that may point to the issue.
I think the tranny is hooped. Who knows, but I am sure I will be in for a fight from Nissan if it does need to be replaced.
I will keep you updated
