Transmission By-Pass Still Relevant? 125,000+ Miles

[SimulatedZero]

I'll be in Orlando next week! Thank God, its freakin' cold here right now.

Ahahaha, I think you'll love it down here then. I just got back from a surfing trip to West Palm and the weather was 78-80F for the high and upper 60's for the low. Love Florida winters

Don't sweat it man, do the by pass if you don't want to have the catastrophic contamination. I've logged 100,000 miles after the bypass; my tranny is like the day I drove it new off the lot and I have only done one drain and refill in 165,000 miles driven, fliud looks and smells fine.

yep, you can always replace the radiator any time in the future, but at least do the by-pass for now
invest an hour, and save yourself the aggravation and expense of a transmission failure

Yeah, I'll be knocking it out today. I figure it'll survive the short while until I pop in a new radiator. I think I may also put a fuel filter with a by-pass valve on the line to start filtering out some of the clutch particulates. I read about another guy doing that somewhere... I can't remember if it was this forum or not. Seems like it may be over kill, but it might help get a few hundred thousand miles out of this transmission.

Rather than use a fuel filter, why not just use an inline transmission filter? You can get them at most auto parts stores. Wix #58964 is one that's available for under $15.

The guy that originally posted that idea wasn't satisfied with transmission filters because they didn't remove small enough particles in his opinion. He wanted the fuel filter to grab the really small stuff that other filters miss.

I'd venture to say the restriction and pressure drop created by a filter like that would not be good. Fuel is running at a higer pressure than the coolant.

[SimulatedZero]

Hm, that's mostly what I was thinking as well. I just wasn't sure so I figured I'd ask. Either way should be enough to collect all the clutch material along with what ever other metal shavings and the like are there, right?

So, I'm looking at radiators online and I have found a couple over at Amazon. I found the Spectra Premium Radiator for 165 with free shipping and I found another radiator for a little bit less. The later one says that it is a "Complete Aluminum Radiator", but I'm not sure if it is really a full AL rad or if it is just a wording trick.

The other thing is that there have been a few comments made that aftermarket rads aren't the most reliable. Almost a pot luck situation on getting a good one. What do you guys think about a Spectra or other aftermarket radiators quality?

I ran a spectra in my 98 civic for 4 years, and never had a problem.

I have an 08 V6 with 45532 miles on it and did not do bypass. No issues yet.

[smj999smj]

There haven't been a lot of reported radiator failures on the 08 models, so far, but there have been a few. The majority by far have affected 05 through 07 models. That said, 45000 miles is fairly low. At this point, you would still be covered under the 8 yr./80000 mile warranty extension.

Spectra Premium is a Canadian manufacturer of radiators and have a good reputation. The only "all aluminum" radiator that I know of on the market for the 05-and-later Nissan Pathfinder/Xterra/Frontier is made by Griffin radiator. Last I heard they were going for around $550. The genuine Nissan radiator and most, if not all, of the aftermarket radiators feature an aluminum core with plastic tanks. The radiator I chose was $92 including free shipping. I got it through Parts Express on Ebay. The radiator was made in China and had a lifetime warranty. It fit perfect and appeared to be well built. So far, two years and no problems.

I picked up my OEM radiator for $420 plus shipping from Courtesy Nissan. Shipping was $35 but I'm sure that would depend on where you live...I'm in OH. I would have considered an aftermarket more closely for an '05-'07 model but all the aftermarkets showed the same part number for '05+ and the '08+ radiator have some slight differences.

New to forum I have 2006 2.5 dci 80.000 on clock no probs yet but worried now is it easy to do bypass and what will I need
