'38 and '40 pickup transmissions
My '38 pickup has a 4 speed and I wondering if a '40-'41 pickup 3 speed will interchange and will it be synchronized like a '40 or '41 car transmission. Thanks. Jim

Re: '38 and '40 pickup transmissions
I believe it should swap, I don't have a green bible to go by though. So you'll have to check.
The clutch shaft is a possible issue, that maybe just a swap with the 38 one. The 40-41 three speed should have same insides as the car transmission 're synchro on 2-3 shift. It may have slightly different 1st and 2nd ratios to the car trans, it's not that different, most don't even notice. Kube would be the man that knows this 38-40 swap ability 're the clutch shaft. This is right in his era. Others will have probably done this swap. Martin. |
