Best, Easiest standard transmission conversion for 27 T
Hey guys What would you recommend for the conversion of a floor 3 speed transmission to put behind a 27 T engine.
Thanks Mike
Thanks Mike

Re: Best, Easiest standard transmission conversion for 27 T
Talk to Mark F at Model T Haven, and bring a fat checkbook. I know he had a Himico transmission/engine made back in the day for a model T. I don't know if he still has it?
Chevrolet transmissions can be adapted to fit in behind the model T's planetary more easily than most others because the U-joint and four-bolt bell coupler is fairly compatible with the model T's. I have heard (but not seen) of Chevy transmissions from the late '30s being used because they have syncromesh on second and high gears.
I have never considered that a very good arrangement because you still have to use the model T's clutch which I love in a model T, however it is problematic for pure clutch usage (removing the bands would help with the use of the clutch?). Personally, I like using a model T planetary with a Warford or Muncie behind!
A full clutch, flywheel, and transmission conversion properly done would cost a BUNCH! (Don't forget oiling!)

Re: Best, Easiest standard transmission conversion for 27 T
Easiest and the most sanitary and still look original would be a Ruckstell. Easy to shift and you effectively have 4 speeds forward and 2 reverse. Add a foot throttle and you can shift all 4 with ease. But with any auxiliary, you will need good brakes on the rear axle.

In my case I got really lucky and found a original era bolt in transmission conversion that replaced the original transmission and hogshead with a 3 speed sliding version built in Canada

Re: Best, Easiest standard transmission conversion for 27 T
In my opinion, there is not an easier to fit, more satisfactory result and wonderfully easily operated transmission them a Layne Warford style auxilliary gearbox. These give excellent results, and you can still drive the T exactly as is standard if that is what you like to do.

Re: Best, Easiest standard transmission conversion for 27 T
The simplest, cheapest and most trouble free conversion would be to swap your Model T for a '27 Cheby.

Re: Best, Easiest standard transmission conversion for 27 T
None in my OP are EASY to install, but something like a Jumbo that has 3 speeds and reverse. You however would still be working with a wet disk clutch even if you removed the low and reverse bands. Ford may have kept the disk clutch in the early A's, but it was dry disk.
I know the voices aren't real but damn they have some good ideas!

Re: Best, Easiest standard transmission conversion for 27 T
Rich, whoever heard of a trouble free 27 Chebby?
The wet clutch is not a problem to Layne style Warford. You just haul on the lever and it will change without using the clutch. A foot throttle helps to match the engine revs, but is not essential.
Why? When I built my extended chassis 1917 shooting brake which can carry 8 adults, it features a rather heavy solid timber body. The Layne gearbox allows me to get off the mark easily, with no lugging in top gear. It drives just like a 3 speed. When it is rolling under favourable conditions, it can certainly take advantage of the overdrive gear.

Allan, I didn't mean the Cheby would be trouble-free. Just the "conversion" !

If you knew the trouble that would cause you, you might want to consider leaving it alone. Been there, done that.

Re: Best, Easiest standard transmission conversion for 27 T
Now IF he was looking for a 4 speed or a automatic then I could offer some true insight into some solutions. A Volvo 4 speed can be bolted in the same space that a Warford takes. 4 speed all synchro!! Or 4 or 5 speed from a Mustang 2. Drive line gets a bit more complicated

Hank,
You had some Chevrolet transmissions for sale that were modified to fit the T driveline. Maybe he could use one.

Ted,
You have to do modifications to the torque tube, install accessory brakes, etc. Works excellent but comes with $$$$ spent and time. Just saying. Thank You though.

Good decision to leave it alone, Mike. Stick to your decision. You'll be happier in the long run.
