1939 Chrysler Cruise and Climb overdrive transmission.

Recommended Posts

I have a 1939 Chrysler “cruise and climb” Overdrive transmission. It came out of a ‘39 New Yorker and I was keeping it as a spare for my ‘39 Imperial but it’s been almost 10 years and I haven’t needed it yet...”Kiss of Death, I know”...

Anyway, I’m not sure if this transmission will fit all ‘39 Chrysler products or just the Straight Eight cars...nor do I know if the Overdrive unit is interchangeable with other Chrysler products from that era. It is the Overdrive that is the real jewel here as it makes these cars so much more drivable as both the eights and the sixes can cruise down the road at highway speeds without issue. My Imperial has the standard 4.30:1 rear end ratio (the non O/D cars had 3.90:1 gears) and even with these 4.30’s (short leg gears) I can still drive her all day at 75 MPH with ease. I’ve actually thought about swapping out the 4.30’s for the 3.90’s to make it even more highway friendly but would hate to lose the low end. 

If anyone has more knowledge of the interchangeability of these transmissions or even the actual Overdrive unit, or is interested in the complete transmission please let me know. Thanks.

Do you still have the 39 overdrive that you had for sale?

Here's a link to a C/L ad offering a '39 Chrysler motor and overdrive transmission for $500. He's has been offering it for a while now, maybe he would separate them. The location is Sanborn, MN:

Slow to see this.  That would have been worthwhile if usable.  If it comes back, I could be interested in the engine - especially if it’s an 8.  

 

...I lived in Bloomington, MN for a few years right out of school.
