Re: Volvo vs. Mitchell Over-Drive - who has what?
Like Tom Endy I run a Ryan in my '30 Tudor and it is a fine unit. I have driven it to Colorado, Canada, Michigan, and many other states. Been up Pikes Peak with it.
I run a 3:54 gear set with 23% Ryan overdrive. It makes it a good around town car and a great highway cruiser as well. If you can find one used I would snatch it up in a heartbeat for the right price. Larry Shepard |

Re: Volvo vs. Mitchell Over-Drive - who has what?
I love my Volvo Overdrive.
I do love the F150 4 speed conversion and would buy one in a heart beat... However, we did the Durango Colorado tour last year. We had the Volvo and a 1939 transmission. Other cars had the F150 4 speed. We were passing all the cars with the F150 4 speed because we were able to split gears. We used 2nd gear with the Overdrive on going through most of the mountain passes. it was great. Lots of power, lower RPMs than regular 2nd. I would go with a torque tube Overdrive and a synchromesh trans vs the locked in OD that the F150 trans provides.

Re: Volvo vs. Mitchell Over-Drive - who has what?
I have a Mitchell in our touring car. I use 3rd gear and overdrive quite a bit when on the freeway in Minnesota. 2nd gear and overdrive is great in the mountains. I have about 80,000 miles on the Mitchell and have only changed the gear lube. It is highly reliable. The installation was a 1/2 day project in my own shop.
I have no experience with a Volvo OD other than driving a car with one about 10 years ago for a short time. As I recall, the shifting was not as precise. Both were very quiet when in operation. Good Day! |

Re: Volvo vs. Mitchell Over-Drive - who has what?
My '31 Roadster P/U has BW since 1998. With a 33% step up it's great for a light car/truck.
My '31 Slant T/S has a Volvo built by Rich Little has been in 2 Model A's so, first installed in 2002. Works great! |

Re: Volvo vs. Mitchell Over-Drive - who has what?
I am with Dick M I believe the Mitchel and the Volvo/Laycock are excellent units-both seem to be bullet proof the only difference is in the shifting and price. One has an extra lever in the cab for shifting. The Laycock changes with the flick of a switch attached to the gearlever just like an auto and very easy for splitting gears. Down here a Mitchel costs about $3500.00 compared to about $1800.00 to have a Laycock fitted (Sorry as you say fit) Mitchel have a number of ratios available where the Laycock/Volvo is mostly 25% with some at 28%.

Re: Volvo vs. Mitchell Over-Drive - who has what?
Would the Volvo/Laycock be able to handle use in an AA?

Re: Volvo vs. Mitchell Over-Drive - who has what?
I have three Mitchells and am very pleased with them. I had a Borg-Warner and replaced it with a Mitchell like the Mitchell much better. I agree the OD is a very good addition to the Model A. In my experience the OD did not increase the top speed.

Re: Volvo vs. Mitchell Over-Drive - who has what?
31 A: " In my experience the OD did not increase the top speed."
______________________________________ Of course, we all understand that an O.D. allows the same speed at a much lower Engine RPM than a stock system, and I do notice that. But 31A, now that you mention it, even though the Mitchell O.D. is theoretically supposed to give a noticeably higher top-end speed, I do not know IF my Mitchell actually does that. I am handicapped in doing an 'evaluation' because of the specially-built Ron Kelly 'Touring Engine' that powers my Dlx '31 Coupe. With it's Stromberg carburation/manifold, F.S. Electronic Ignition, Exhaust Headers opened up, etc., etc., the car just goes FAST and POWERFUL. And while it does reach a comfortable cruising speed of 60 mph, so does my stock '28 Phaeton. |

Re: Volvo vs. Mitchell Over-Drive - who has what?
I guess I might be old school. While I did improve brakes with cast iron and safety with 12V for lighting etc. I guess if you are looking for more speed and are willing to spend the bucks on overdrives (none even close to orig.), why mess with the underpowered model A engine? At what point have you crossed the line and now have entered the "Custom Car" arena? Just asking...

Re: Volvo vs. Mitchell Over-Drive - who has what?
The Volvo/Laycock overdrive is now serviced by GearVendors and they use these similary if not the same technology in 2000HP race cars, rock crawlers, fleet vehicles, 4x4 equipment, etc. It's a good solid unit. I think you would have no problems with one spliced into the torque tube of your AA.

Re: Volvo vs. Mitchell Over-Drive - who has what?
Within the spirit of 'controversy', when all the 'dust' has settled, it must be said that at the very bottom of the discussion there is the fact that using an over-drive, does for the most part, reduce engine RPMs for the same driving speed as a non-O.D. engine. As such, it would seem to me (a non-mechanic) that the reduced RPMs should help increase engine life, while still giving good motive power. That is to say, an O.D. gives the same speed as a non O.D., with significantly reduced engine RPM, hence (all things being equal) longer engine life.
Of course, all things are seldom equal, so in the long run, perhaps it really does not matter. But if nothing more than psychological, I REALLY enjoy having a Mitchel Over Drive in my '31 Dlx Coupe. And 65 years ago I enjoyed having a Columbia Rear End in my '28 Sedan. |

Re: Volvo vs. Mitchell Over-Drive - who has what?
Reduces engine RPM, prolonging engine life AND saving gas.
There is an ROI case that can be made for purchasing one.
