Unknown history, change 6mt fluid?
Hey guys, I'm about to hit 75000miles in my 04 6mt coupe. The history of this car is unknown, but I'm wondering what the pros and cons are with changing the tranny fluid considering it may have never been changed. Same goes for the rear diff.
I've noticed some scratching (that nasty gear noise from a bad shift) of 2nd gear recently. This may be due to driver error and not pressing in the clutch long enough when shifting into 2nd. I'm a bit afraid I may have a huge repair bill in my near future. ****.
I've heard horror stories of people changing fluid and then the tranny won't work, but I obviously don't know any better.
Advice?

This....^....is only the rule of thumb when changing AT fluids not MT! You're better off changing your MT and Differential fluids with AMSOIL synthetic regardless of the mileage! Runs cooler and shifts much better than Nissan OE trans/diff fluids!

this subject came up with another post previously, a tech told me if it was 90K+ to not bother to do it, would possibly cause leaks that were not previously there.... so at 75K you should be ok, but also recommended to stick with OEM fluids.... not sure when the suggested Trans flush is, mabye 60K so you should be fine

Have you personally switched from OEM nissan MTF to Amsoil on the 32010-CD001 - 32010-CD009 series transmission on a V35 Coupe, Sedan or Z33. I would not be giving advice on using products in which you have not personally used in the current applications. What works in a different nissan transmission is not the same for the current transmission topic discussion. Many have spent $$$ switching to amsoil for transmission just to switch back to OEM due to notchiness in the shifts and roughness. I would stick to OEM GL4 MTF.

OE fluid is decent, but still used on a budget to keep costs down. its been proven time and time again with thermal breakdown tests among others that OE is not always the best option. If your car is under warranty then sure, use OE fluid to ensure that there are no implications with warranty work. but if you're out of warranty then there is absolutely no problem switching to a reputably fluid like Amsoil or Redline. They didnt build their reputations by selling **** products. OE fluid is hyped up BS that the dealer will tell you to leave in your car for FAR longer than it should be.
OP, you have absolutely nothing to worry about by changing out your transmission and differential fluids. Its just a drain and fill procedure so no harm no foul. The problems you have heard about are referring to automatic transmissions because a fluid change actually involves flushing and back-flushing the fluid through the transmission and the transmission fluid cooler. It sends all the contamination and metal particles through wherever the fluid travels. It can gum up the valve body, and other parts of the transmission. Most places that have had these bad experiences will recommend just draining/filling and replacing the fluid filter.
Moral of the story is change that **** out. buy some good quality fluid like Amsoil or Redline and be done with it.
