I have one. I love it. 27 percent overdrive in any forward gear at the flip of a switch.
Thank you all for the responses. This is encouraging although not surprising. I retired my '85 240 wagon and loved the O/D trannie so much I saved it for a project in the garage.
well it's good to know that at least the overdrive unit has been done before. I see what you mean by major surgery for the use of the gearbox as well. Thank you for comments!
FYI, the unit is a Laycock J type and has a small switch in the gear stick -super convenient! I imagine that other people have changed the set up so that it can be used in all gears.

When people talk about the Volvo Overdrive, it is the same concept as the Mitchell Overdrive. It is the overdrive unit spliced into the torque tube. Just like the Mitchell box, except the Mitchell uses levers, like another emergency brake lever, and the Volvo Overdrive is activated electrically.
top is a Mitchell, bottom is a volvo
You send one of the vendors your torque tube, they send you back a "bolt in" stock length torque tube with the Vovlo Overdrive unit now in the torque tube.
My thinking was that if you had unlimited money, you could get one of the Model A Only ( http://www.modelaonly.com/about_us ) bolt in "no modification" 4 speed transmissions, and then also get a torque tube mounted Volvo overdrive and have essentially 5 gears, if your engine was strong enough, and all hypothetically a bolt in application.
