Topic: 3-Speed Overdrive Question


dennisj1633    -- 03-23-2018 @ 9:28 AM
  I have a 1953 Customline Club Coupe that I am interesting in converting from the standard 3-spd to a 3-spd overdrive transmission.
What would I encounter in attempting this and what year ranges of transmissions would be applicable to my car?
Are there any good transmission sources out there that I would be able to obtain one from?

Thanks in advance for any and all help! Dennis

  You might want to contact Mac Vanpelt at www.vanpeltsales.com, 513-724-9485 to find out what has to be changed and what parts he has available for such a conversion. A good source for the solenoid, relay, and other small electrical parts required for the conversion is Randy Rundle at www.fifthaveinternetgarage.com, 785-632-3450.

  Any 1952-54 Ford passenger OD trans will fit.....they were all the same during these years. The driveshaft will be the same on the car whether it was originally a regular standard transmission or the overdrive option.

PS: our phone is 513-724-9486. The 9485 number is not used anymore.

  I have been getting together all the parts and pieces to install a overdrive in my 50, you'll need a transmission with a working governor and solenoid, a relay and kickdown switch along with a lockout cable. The first trans I got from a friend is a 53, it is 2 1/2 inches longer than the 50. If you go looking for a trans measure the length of your stock trans from bell housing face to the mount and from bell housing to the end of the tail housing. There are many different set ups. I found a 51 which uses a different mount than the 50, also its one inch closer to the bell housing requiring lengthening the mount. On some you have to turn the mount around for the overdrive trans.

  I installed my overdrive transmission Saturday, it made a big difference. I don't have a tachometer but in overdrive at 60 the engine sounds like it did doing 45 with the stock 3 speed.

  Great. It should reduce the engine RPM by 27% when engaged.

  As a general rule a vehicle with a factory OD trans will have a lower differential gear ratio than a non OD vehicle. Example; a '58 Ford F100 standard gearing is 3.72, with OD it is 3.89... Late model GM C-10 pickups/SUV 3.42... OD 3.72
My brother has a very nice "53 with a '76 SBC, 350 trans and 10 bolt differential.. It' WAS' a great running car with 2.08 gear ratio, a friend of his talked him into putting a 2004R OD trans in to the car. I told my brother the axle ratio was to high and that he would have to re-gear it. My brother don't like to listen to me.. The '53 is almost un-driveable, Won't pull it's self in OD under 70 mph, has to drive the car in D or 2 in town.

  I have been looking to replace my 51 ford standard 3 speed with an overdrive unit. It looked like everything would fit until I measured the rear mount and found that the crossmember supporting the trans. would have to be moved back several inches. Deal breaker for me.

  disregard my post-turns out my o/d trans is not a 51.
