Pennzoil Synchromesh in NV5600

[moparmarty]

I'm getting ready to change my transmission fluid after 16,000 miles of mostly towing my TT. Not wanting to pay $11. 25/qt for Mopar oil, I researched this site and TDR back issues. I'm a little confused.



In TDR issue 44, page 144 it states: "The NV5600 uses a synthetic 30-weight oil. Pennzoil Synchromesh, 30 weight synthetic fluid is an acceptable alternative. "



On the Pennzoil Synchromesh bottle ($4. 99) it does not say it is synthetic but it does state: "Meets Chrylser Specification MS-9224. Suitable for use in Chrylser transmissions requiring Part No. 4874464 (the specification and part number listed in the factory manual).



I cannot find a Pennzoil Syncromesh synthetic. Is the factory oil synthetic? Is TDR issue 44 incorrect? Can I use the Pennzoil Syncromesh non-synthetic without putting my transmission in harms way to save $37.

I think the TDR was in error. The Pennzoil Synchromesh fluid is not synthetic, but it does meet the MS-9224 spec. See http://www.klenger.net/dodge/general-reference/nv5600-fluid/index.html for some more info.

I am looking for the Pennzoil Synchromesh fluid here, haven't found any yet. Klenger, didn't you say on another thread you had used it with good results?

OCarney: I found it at Autozone.

I've had no problems and notiiced no real difference from the stock fill. Many others have used it also. I got the last batch from AutoZone, but you can also buy it direct from Pennzoil.

I was confused too about the fact if it was synthetic or not... I assumed it was because of the article in TDR issue 44 that you mentioned. But I know klenger usually has his ducks in a row, so I'm sure he's right!



I had to do some searching to find the Penzoil too, ended up getting it at Autozone, but the Fargo store only keeps 2 quarts in inventory, so I had to order a bunch just to perform one oil change. When I ordered, I ended up getting 10 quarts, which should keep me going to two oil changes.



I noticed a fairly significant improvement in shift quality after my first oil change (at about 6,000 miles), and I plan to change once every year from now one (about every 30,000 miles).
