Penzoil tranny fluid
I saw this today and thought of getting it because I am having a hard time finding GL-4. I thought I would post some info here, anyone using this?
Pennzoil® Synchromesh Fluid
Pennzoil® Synchromesh Fluid is a synchromesh transmission fluid designed for certain manual transaxles and manual transmissions used by General Motors or Chrysler. Pennzoil® Synchromesh Fluid is formulated with high-quality paraffinic base stocks, a fluidity modifier, multifunctional performance additives, corrosion inhibitors, a foam suppressor and a shear stable viscosity index improver additive. It provides excellent oxidation stability, low-temperature performance, excellent synchronizer performance and compatibility with yellow metals, such as bronze, brass and copper components found in manual transaxles and transmissions. This product will satisfactorily lubricate General Motors or Chrysler manual transaxles and transmissions from -40°C to +150°C.
Benefits:
* Exhibits excellent low temperature performance.
* Meets GM Specification 9985648 and Chrysler Specification MS-9224.
* Suitable for use in GM manual transaxles and transmissions requiring GM Part No. 12345349 or 12345577.
* Suitable for use in Chrysler transaxles and transmissions requiring Part No. 4874464.
* Excellent synchronizer performance.
* Excellent yellow metal compatibility.

This has been discussed to death as I am sure you are aware? Got a Napa Auto parts in the area? Get the real deal. My local Napa stocks it. They can bring it in in a day or two if they don't have it.

Yup! I was the last guy to bug everyone with the question and I can attest, NAPA does have it or can get it in very short order. They also have the snazzy pump that goes with it too.tractoman wrote:This has been discussed to death...

Sorry about that. I did not see the pennzoil one in any of the few discussions that I have read. It was more desperation than anything I saw that stuff today and thought hhhmmmm I should ask the forum before going any further. I will make a point to hit a NAPA soon. I hardly ever get in to town.
Thanks, I will steer clear.

That Pennzoil product does not carry a GL rating. That doesn't mean it does not meet the specs, but it has not been tested to those specs (why would they if they were trying to meet specific GM and Chrysler specs only?) It may be fine, but I wouldn't risk it.
If you want super synchro performance, I'd go with synthetic instead.

If you are using a low grade oil like Penzoil, you would need to use their GL4, and suffer the possible consequences of a lower EP (extreme pressure) protection level. If you are using a high grade oil like Swepco, you can safely provide your transaxle with the high level EP protection of a GL5.
The GL4/GL5 debate should have died away MANY years ago, but remains because there are low grade gear oils (like Penzoil) still on the market. To explain this further I quote a smarter guy:
"Clarification on S-P additives and the GL4/GL5 quandry:
The Zinc-Sulfur-Phosphorus package in GL4 lubes is 1/2 to 2/3 the level of the GL5 lubes.
The difference in add levels is due to the fact that manual transmissions don't need as high a level of EP adds for the spur gearing, whereas hypoid differentials need extra EP because of their high loads and extensive shearing actions.
Most gear lubes today use the "non-reactive" sulfur-phosphate packages.
By "non-reactive," we mean that the sulfur is not just 'elemental' sulfur dissolved in oil, which would react with the metal to stain and corrode copper-containing metals such as brass and bronze.
Rather, the new S-P add packages are esterified (incorporated in fats) S-P's. These only react under pressure/heat of shearing and loads to form FeP and FeS EP surfaces films to prevent galling and wear. TBN boosters (TAN reducers), antioxidants, metal deactivators, and rust inhibitors are also incorporated to prevent acid buildup and to protect from rust."
