96 pathfinder transmission downshifting or changeing gears by larry141

I have a 96 LE pathfinder--I think it has a sensor problem--While driveing after it warms up it sometimes goes into a downshifting mode and the RPM jumps up and after awhile it will shift back to a higher gear.It has gotten bad over time.I think it may be a heat sensor in the transmission but I am not sure.Has anyone had this problem--Sometimes it will change gears 3 or 4 times in a short time.Never does it when it is not warmed up Thanks

theres a speed sensor in the tranny usually on the side, let a good tran ny guy look at it and adjust it or replace it.

The mechanic told you the right thing, I have 2006 pathfinder and it does the same on slope roads in terms of being in drive but it would role back alittle which is normal.I wouldn't shift gears on the slope or even park on it to be honest with you because the owners manual said that the pathfinder should be parked on even grounds.

How's that class action suit coming? My issue with all of this is... If I hadn't done any searching about the problem online, I would have never known about it. I took it into service and already had it diagnosed for them. Nissan has obviously known about the problem for some time now. You would think they would have informed their customers about it so they could have the option to do some preventative maintenance, if nothing else. Even out of warranty. I would much rather have replaced my radiator, instead of the radiator and transmission. But wasn't given the choice...

As I understand it the main problem is not really with the radiator itself but with the transmission fluid cooling line within the radiator that is prone to failure. The solution is not replacing the radiator but by-passing the cooling line within the radiator so that even if the cooling line eventually fails the possibility of coolant contaminating your transmission fluid is completely eliminated.

so if you bypass theinternal cooling line you need to reconnect it with a tranny cooling line bypass kit ,is this correct?

Yes. It looks like a mini radiator, with one inlet and one outlet. Doesn't matter the flow as long as it goes through it.
