#1231 of 1242 transmission / coolant problem
Aug 13, 2013 (1:19 pm)
i have an 05 pathfinder with 49K miles. i have not experienced the coolant problem yet, but want to avoid it. is there anything that can be done in advance? eg, replace radiator or replace transmission cooler or both?
i came here because my service engine soon light came on, but glad i did!
thanks in advance.

Bypass the transmission line going through the radiator.
There are several suggested DIYs in the thread but the one I used involved pulling the transmission fluid hose (short one) from the radiator at the left end and rerouting it to the transmission line where the long hose from the radiator is connected. Pull out the long hose and connect the short one there and now install the long hose over the pipe on the radiator from which the short hose was pulled. This is just to cover and protect the line so that dirts do not go into it.
I did mine more than three years ago and I have not had any issue with the vehicle since then although I do not tow, but I do carry over 500 kg at a time worth of loads.
If you go through the thread, you will pictures to guide you.

thanks, i will search for the diy.
essentially we are "shorting" the fluid circuit so they dont mix. i guess i could look for an aftermarket trans fluid cooler. Does anyone have a suggestion that worked for them in the past?
it seems if newer models still exhibit the same problem then this is a flaw in the design and not a bad component. replacing the rad will be of no long term benefit.
thanks everyone for alll their posts.

We had our transmission cooler line routed directly to the transmission cooler. Bypassing the radiator all together. A nissan technician at our local dealer did it for $25. He said he's done it to his two Nissan's to avoid the problem and avoid having to put in a new radiator. Your Pathfinder should have a transmission cooler so you should not have to buy that.
#1235 of 1242 Settlement is a joke
Sep 29, 2013 (9:42 am)
The class action settlement going on now is laughable. I thought the settlement people were working for us but they are crooks just like Nissan. They are making it almost impossible to get any monies back. They have all they need form our receipt, the fact that we broke down 200 miles from home, towed to Nissan. Replaced the radiator/transmission etc. Two and half years ago the RO didn't say it was leaked radiator problem. Dealership has changed hands and said they will tell someone it was the radiator leak but can't "mess up their paper work". Settlement people say I need to get it in writing or no deal. Crooks, all crooks. Pathfinder ruined us. Beware

FIRST OF ALL YOU NEED A TRANS COOLER then a mechanic or your self can by pass the radiator

unfortunately it seems what your dealer wants to do for you, some people have had the entire trans and radiator replaced for nothing ,

Please do not, do not buy a Nissan. My transmission failed and Nissan does nothing to help. You will be on your own with costly repairs. Go with a Toyota or Honda please

Hi. I see your message is from 2010. After you fixed the truck, did the problem ever happen again? Also, would you happen to know if replacing the trans is absolutely necessary or is rebuilding it enough? Thank you

Did anyone ever have any luck with just flushing the trans?
I have a 2005 Pathfinder and it just started doing the vibration at 40mph. I was wondering if I can flush it and at least get it good enough to trade it in without anyone asking questions.
