Probably you are right, BUT still I would not take it so easy.smj999smj wrote:Nissan-matic J is nothing more than Castrol Multi-import ATF, only in a bottle with the Nissan name and a $3/qt. higher price.

I never said anything about using "universal ATF." I said,"Most synthetic ATF's are fully compatible with Nissan-matic "J" and "S." One should always check to make sure the ATF is recommended for use in Nissanmatic Type "J" or "S" applications. Most synthetic ATF's do comply to the JASO A1 specification.labsy wrote:Probably you are right, BUT still I would not take it so easy.smj999smj wrote:Nissan-matic J is nothing more than Castrol Multi-import ATF, only in a bottle with the Nissan name and a $3/qt. higher price.

- First, if you go through R51 service manual, there's just a specification of liquid requirement for engine oil, brake and steering fluid, coolant etc...but when it comes to ATF, warning to use only original Matic J it is not only printed out in bold, but in bold red color. Indeed it's partly marketing, but still there's a lot of truth to be careful what you pour into your tranny.
- Second, Nissan MAtic J is really, as you say, semi-synthetic Castrol Transmax J (or Import Multivehicle in USA) ATF, so exact equivalent is just that particular ATF. There are many universal ATF on the market, but what you need to look for is JASO 1A specification. The Japanese standard of JASO 1A spec actually far exceeds the standards of most other ATFs that manufactures require for their trannys. Nissan adopted JATCO transmission and Castrol Transmax J ATF, tested it and that's what 100% fits. Also applies that any universal JASO 1A spec ATF will work just about the same as Matic J, but that does not mean any universal ATF is good for R51 transmission.
- Third, Nissan Matic S exceeds Matic J and is fully synthetic ATF, which is recommended for R51 tranny.
For the end I'd just add my 5 cents of experience when changing ATF fluid. Have fresh bottle opened, smell it and pour a drop onto white paper.
Then check ATF from tranny and pour another drop of it with dipstick on the same paper. Compare color, viscosity and smell.
If it is much darker (fresh ATF is pinky red, old is kinda yellow brownish, like fresh motor oil) and if it smells burned, then do not proceed with full ATF flush! Some say in such case it's better to leave it as is, because it's full of friction material, which provides at least some functionality to your tranny. But I guess it's safe to just drain most of ATF from tranny (leaving approx. 40% of it in torque converter and pump), which is approx. 5 litres out of 9, so it mixes with old ATF.
I've heard quite some stories of people instantly destroying their tranny after ATF being burned, they fully flushed it out, replaced with fresh...and after few weeks they needed new tranny.
Is this the right one? http://www.amazon.com/Castrol-06814-Mul ... l_huc_itemsmj999smj wrote:AFAIK only original Nissan Matic J or Matic S is the way to go.
