|
|
I am changing the fluid in my tranny. I removed both drain plugs. Is there only one fill plug or two? I found the one on the gearset part but I dont see one on the differential part. Am I looking for a fill plug that doesn't exist? _________________ 1962 VW beetle-The project

I believe there is only one fill plug. Two drain plugs. |

Throw that Chilton book in the trash. Or put it next to the toilet for emergency toilet paper. Any other manual out there is better - the Bentley being the best, of course, but I'd take a Haynes or Clymer any day over that POS Chilton book.

There's only one fill and it's on the driver's side. _________________ Glenn

A tip on changing tranny fluid.
Always be sure you can get the fill plug out before you remove the drain plug or plugs.
If you can't get it out, you can't refill it.
That would suck if the old fluid was already drained....... _________________ Gary

any pics or diagrams of where these 3 plugs are located? I was under there the other day and noticed a plug right in the middle on the drivers side, is this the fill plug? Then I guess the 2 drains are on the bottom of the case? Thanks guys. oh yeah also, is there a certain type of fluid needed for this? I have a 64type1. |

Someone correct me if I'm wrong. VW used the 80/90 oil in the trans/diff because it would not foam. Foam in a trans/diff would greatly reduce the lubrication. I've been told that lighter oil can be used as long as it is a non-foaming formula (i.e. synthetic). Does anyone know for sure? _________________ Ted Wojton

VW never spec'd multi-grade gear oil because it was more expensive than mono-grade. They spec'd 80wt gear oil for winter use, and 90wt for summer use.
All gear oil has anti foaming additives (same for engine oils), so you don't have to worry about this.
For gearboxes, I recommend synthetic gear oil, 75W-90. It shifts way better than the cheap stuff. Since you leave it in there for 30k miles, it is easy to justify the cost. |

The bad part about it is that the Chilton book even has a picture of where the Diff fill plug is I can see 2 plugs in the picture but only 1 on the Tranny. The book also tells you how to do the timing so its 180 degrees off. I found that out when I advanced my distributor 180 degrees and the engine started running . Mostly I keep it around for the notes I wrote in the margins but after this its going to get demoted to shop rag status. _________________ 1962 VW beetle-The project

The only other lighter lubricant I've ever heard of in regard to the VW transaxle is to use ATF if it is really really cold. Below like -13°F if I remember right, and if it got warmer, they wanted hypoid put back in there ASAP. As for foaming, I don't know about that. However with modern synthetic hypoid, in cold climates I'd go with that. I used it with the original tranny in my 62 for a couple of years and it made a noticable difference in cold weather.

From 61-69, all Type 1 gearboxes had 2 drain plugs. This was needed because the forward gear chamber was not connected at the bottom to the diff chamber internally, so you couldn't get all the oil out with just the diff plug. Then in 70 they altered the casting to allow a passage to drain the forward gear chamber into the diff chamber. Thus they only installed one drain plug from then on. |

75-90 synthetic redline is what I started running,it shifts so much better than it did with conventional oil. |
