How to disassemble a 39 Ford transmission?

[1stford]

You might look at Mac Vanpelts website, He has great diagrams on there.

Yes - buy the book from Mac "The Ins and Outs of Early Ford Transmissions" - because if you need a bit of help taking it apart, I guarantee you'll need more help buying the correct parts, understanding the necessary clearances and putting it back together.

It isn't that hard, but a good book or two (and good parts suppliers) sure helps!

Mac's In's and Out's, another good reference is the Vern Tardel booklet #2 Ford transmission service and repair.

After your rebuild fill it with GL-4 gear lube, I get mine from O'riely that sell a gallon Master Pro Chemicals GL-4 140 gear lube. Good luck

Hello Mike, welcome to the forum.

You tend to get back what you put in here.

I don't feel inclined to write an hour long post on how to strip a transmission in reply to a 10 second question.

The above advise is good, though.

Give us some more info about what you are doing, what the trans is for and what you want to do with it. Ask more specific questions and you'll find lots of people willing to give good advise here.

Mart.

X2 what Mart said. Introductions are not necessarily required here, but it does generally help when asking a question here for your first time on the barn. Come back with some basic info on what you are doing and folks here will help you get started on disassembly, but Mac VP's book is a great source of info to have.

Mike,

Put your general location in your profile. It may turn out that you are just around the corner from the best transmission builder/source of parts in the country and someone will point you in his direction.

Think twice on using Master Pro Chemicals GL-4 140 gear lube sold by O'Reilly. I did and it foamed and not just a little as you might expect on heavy lube, but I mean foamed. Yes you need 140 wt and I bought Sta-Lube from the real deal source Mac Vanpelt. Little pricey, but well worth it with no foaming and besides how often do you need it.

Not sure about this foaming, are you seeing this out of your shifter housing cap? Please elaborate as I have almost a thousand miles on my 39 and will be changing all the fluids as I did @ 500 miles for my first break-in/shake down/inspection and fluid change , no foam to speak of and done while hot.

I fill a trans til it comes out of the the fill port, I button it up and take a short drive to warm it up a little. then pull the plug and let the over fill flow out. At that point you can see if there is foaming. The MasterPro GL4 poured out of the side port it was foamy. When I drained the trans it came out really foamy and even letting it sit for a couple of hours, no change. Replacing with Sta-Lube, minimal foam.

Some straight mineral lubricants like GL1 may not have anti foaming agents. The label will only give you API rating and general SAE information with maybe a reference or two to MIL specs. GL4 & GL5 generally do have anti foaming agents (especially since they are blended to API specs) but now days you really don't know what you're getting. Excessive foaming can sometimes cause oil venting but the old transmissions likely wouldn't have much problem with that.

I kind of know what you mean, a fella over on the Model T site had posted about test driving his 21 for the first time on 6-30, we have not heard from him or how he made out.

I hope he's O.K. Scott
