When I changed mine all I did was pull the drain plug. About 1 gallon came out, I installed a tranny cooler and put 1 gallon back in. To bring it up to the high hot mark it ended up taking another quart. I should have pulled the pan but the fluid looks perfectly clean so I ain't sweating it. YMMV

Hey guys this thread is awesome! I have a 95 SE A/T and have been working in auto part sales for the last 10 years (whole adult life I'll admit). I have been pushing the valvoline max-life for years because it's wide range of compatibility with all different manufacturers. I recently discovered Castrol Transmax. Didn't pay alot of attention to it at first until a customer asked me about it. I noticed right away that instead of covering just about everything it seemed to be more geared to Japanese transmissions. I did a little research and found that in comparison it carries fewer "fillers" just as excessive friction modifier which can interfere with heat dissipation from what I've been told. It is the same price too. My SE has 280k miles and the original transmission, I'm going to give the Castrol a chance and see how it goes. I'm thinking about adding Lubeguard platinum to helping keep things smooth. Any of you have any advice or experience with these products?

Yes I have been using Castrol Transmax here in Australia. Used that and just normal Castrol Dexron III. The Transmax costs a bit more but I find shifting gear is easier on the auto, feels better and much smoother changes.

All good I just put a big magnet on the out side of the pan and every time I change my fluids it collects all the metal and gunk 👍. I have never done a flush just because I heard it was bad for a older trans but I'll try it .😀

I need to get some info from all that has changed auto tranny fluids regularly....I'm planning on taking the tranny out of my parts pathy that has about 100-150 miles on it. Yes, it's new. Stopped driving the Pathy once I found out that the frame was WAY TOO GONE & UNSAFE. So, it's been sitting for a few years now. I'm thinking about draining the fluids & refilling once in my other Pathy. Planning on putting the tranny cooler on also. So, that being said.....What type of tranny fluid should I use? I've heard Royal Purple & AMSOIL are really good...Knowing that it's new & fresh fluids, I will plan on changing fluid on a regular basis...20k-30k miles, or 10k less?

Use whatever you want, as long as it says dexron III or nissan matic D on it. I used valvoline maxlife because that was what they had at the time.

I'm lucky I have a drain nut on my pan, so every 2nd oil change I do the trans fluid. I know it's like $48 for trans fluid but I'd rather replace the old stuff rather than leave it until it's too late. To me, the auto trans is like a ticking time bomb, you never know when, so to me it's prevention ($48) is better than the cure ($2,000 at mechanics)
Been refreshing my auto trans fluid since I needed it rebuilt and it's been going great since 2009 and well over 120,000 kms on it so far without any problems.

Valvoline Maxlife is some great stuff along with Castrol Transmax Import.

Anyone who doesn't change it, or believes that "changing it will make it break" crap, is just an idiot and shouldn't own a vehicle.

Ok, this thread has been awesome.  I'm going to be changing out my tranz fluid in the am, and this has really helped me out.  REALLY glad I found this forum.  

 

I'll fill you in on any issues, etc.

 

Wish me luck! HA!

Damn, Adam, chill out a bit...

 

 

What I was told from Nissan Master tech that frequents this site is that Dexron III/Merkon is perfectly adequate, but might need more frequent changes due to heat specs.

That said, my 1995 needs new fluid, so I'll probably flush it out with some D3/M and then add the Castrol Transmax.

I've had good luck with Castrol products over the last 20-30 years. Maybe there is something better, but hey, maybe the brand is to be trusted in this application?

I've used normal Castrol Dexron III and I find it doesn't shift as nice but still it works as it should. Castrol Multivehicle is what I use and it's a bit more expensive but it's the best. I had my trans rebuilt nearly 200k ago and it's still going strong.

Terranovation: can you expand on what you don't like about the Dexron3? and whether that's related to the general air temperature that you usually drive around in??

Dexron III (Castrol) is a generic brand that doesn't specify which vehicle it's designed for. Although it works, I feel the trans doesn't shift as nicely as Castrol Multivehicle because Multivehicle is specifically designed for 'Asian Vehicles' and because Terrano is Japanese built and the trans is Jatco it's built in Japan too. Multivehicle fluid is a darker red too while the generic brand is more a strawberry color so I believe the darker red has a better viscosity based on it's color being 'thicker'.
As for the air temp question, both generic Dexron III and multivehicle both heat up at about the same temperatures, the trans should take 4-5 mins from a cold start, to warm up to 82 Celsius (179 F) about the same temp as the thermostat opens to allow coolant flow, at that stage, overdrive lock up can then occur. During the warm up stage, only 3rd gear is available which is a pain sometimes but it does this to warm up the trans faster. In summer temps, this warm up takes less time. I would say anything over 75 F it's a lot quicker than say if the outside temp was 60 F.

Mine doesn't do that. I have all gears even when cold...only thing it waits for is the locking of torque converter.
