BW R10g1 rebuild parts sources?

[FarmerJon]

Last summer I picked up a R10g1 Borg Warner overdrive transmission, out of a '55. Wanting to get it into my '48 by the end of spring, I dropped it off at a recommended "ol' timer" to do a freshen up. Unlike the transmission shops I had talked to, he immediately knew what I was talking about, and was willing to do the work, but was concerned that he wouldn't be able to find parts. We agreed that I will be in charge of supplying all the needed parts. 

I know that Andy B's has the 3 speed gasket and small part set and bearings but prices seem high. I had previously tracked down all the sealed bearings through normal parts sources for around half the cost. 

Anyone known the actual supplier of these transmission kits? 

What other service parts will I need?

 

I thought someone here had made a post with all the parts needed for these transmissions, but can't find it now.

Thanks guys!

Check with Mark Duggan, he rebuilt an R10 several years back and still may have his parts list and suppliers.  Message via this site to Mark D, or his email is

For gears in the front, I used ebay.  For OD parts, I used vanpeltsales.com for a 12v solenoid and the big 4inch snap ring.  They list parts as Ford, but some fit the plymouths.  A couple days ago I called and ordered a balk ring/gear.  They are used, but he said they are cleaned, inspected and tightened.

 

I'm pulling my R10 soon to replace the balk ring so we'll see.  For $45, I'll take the risk on condition and fit.

Thanks guys!

I will reach out to Mark, I bet his write up was what I remember seeing.

 

Maybe a stupid question, but what is the official name or designation for the base  Mopar three speeds? 

I have onle ever seen them referred to as "Mopar 3 speed", not super helpful when parts hunting.

Were they made by Borg Warner too, or were they a Chrysler product?

I used Northwest Transmission for the 2 ODs I rebuilt.

Try Studebaker International (online catalogue). I bought my 6V solenoid from them and they also have various other OD parts.

That is great! Has the loose rollers for the overdrive, all sorts of snap rings, looks like very reasonable prices.

 

For the trans itself,  it looks like 6207z ball bearing for the front, 6206z for the case extension. I may just have to wait till the trans is apart to know the rear bearing.

I have National 8160s for the tailshaft seal.

Do these numbers look right?

 

 

Len Dawson's has the best price on the rollers and snap rings for the trans that I have found so far, 

Northwest transmission only has mopar Automatics listed, but I will call them Monday and see if they have parts for the manual transmissions.
