Piston Slap: Nissan Matic J Worth The Trouble?

TTAC commentator Kericf writes:

First, an update: I submitted a question on my Rodeo ABS and brakes before. It was just a bad sensor (probably from driving in high water). And I chose not to replace the brake lines yet after inspecting them.

Now, my new question comes way of a transmission fluid change on my wife’s 2005 Pathfinder. As usual the manual calls for only using official Nissan Matic J at almost $13 per quart. The local auto parts store sells Castrol Tranny fluid that says on the label it is a replacement for Matic J. I do not have any warranty left so I’m not so much worried about fighting over what was used, I just don’t want to have to replace the tranny because the fluid wasn’t the right spec? Am I worrying too much about it? Should I just dive right in and go?

I would also like to get some suggestions by the B&B on the best way to flush more fluid out than the standard drain 5qt out of the pan method. Is there a way to really get it all out on your own? I saw the product review on the oil extractor and was contemplating trying one out for the tranny fluid as it seems a lot easier and cleaner.

Piston Slap: Dodging Trouble Again?

Tom in North Carolina asks:

Thanks for taking on the synthetic vs. standard oil change question on my 2005 Dodge Durango a few months ago. Now for a new challenge: the same Durango, 78,000 miles, 5.7 Hemi with 5 speed automatic (trailer tow package and transmission cooler). It’s a highway cruiser, bought it to tow a boat with trailer. Except I have a boat slip now so there’s very little towing needed.

The dilemma: the manual says nothing about changing the transmission fluid if the vehicle is not used in severe service. Since I am skeptical of lifetime fluids, I think the fluid needs to be changed but don’t have any idea when to do so (FWIW: it is still a nice shade of red on the dipstick).

It’s also worth noting that most insurance plans have glass replacement options that can make the repair a low- or zero-cost issue. "Now I understand why my insurance is so high despite no claims for years and about 7,500 annual miles between three cars.
  • AMcA My theory is that that when the Big 3 gave away the store to the UAW in the last contract, there was a side deal in which the UAW promised to go after the non-organized transplant plants. Even the UAW understands that if the wage differential gets too high it's gonna kill the golden goose.
  • MKizzy Why else does range matter? Because in the EV advocate's dream scenario of a post-ICE future, the average multi-car household will find itself with more EVs in their garages and driveways than places to plug them in or the capacity to charge then all at once without significant electrical upgrades. Unless each vehicle has enough range to allow for multiple days without plugging in, fighting over charging access in multi-EV households will be right up there with finances for causes of domestic strife.
