I always thought it would be cool to make a planetary aux gearbox for OD by taking the planetary gearset and clutch pack out of an automatic trans, and using engine oil pressure to activate the clutch pack. If only I had a Bridgeport and 30 years experience...

Also, google "Saturn overdrive" for another option. Good luck!

The Saturn overdrive is made to go on a four wheel drive transfer case. The input and output are on the same side of the unit.

I think there are probably better options for you than the B-W overdrive.

Thanks Albuq-F1, The operations manual for BW OD was useful in understanding its working. And I see that the one-way clutch has some significance in engaging direct drive on the fly.
I had checked the Saturn overdrive (Is it also known as the Warn Overdrive unit?). As 38 Coupe said, I need to make my own casing and install a set of idler gears to have a straight output than from the same side.

Hi, This was the first thing that came to my mind. Using the 4th and 3rd gears and reversing the input & output

. But had to give up this idea as this would reduce the ground clearance, while a planetary system seemed compact with some increase in length which could be tackled by working on the propeller shaft.

Same here, not with oil pressure & clutches but with synchros like in the Saturn OD. In the mileage conscious Indian market the options for an Automatic transmission are very few, and finding one in the scrap yard is still difficult. Also lack of experience in this field is the problem here.

Still it would be great if there would be a way out for complete manual control of this OD unit. Hope to find a solution soon.
