Aux overdrive idea

[electryc_monk]

Any idea how difficult - mechanically speaking- this idea would be to bring to life?

Instead of using a GearVendor or US Gear aux unit.. why not adapt a old 3 speed from an older 1 ton or 3/4 ton f250/350 or larger chassis? And attach it to what ?

well I have the 99.5 F350 2WD SRW automatic with 3.73 ratio in the rearend.

IF its mounted where the tail shaft was and a set of solenoids for shifting from 1,2, or 3 gear and you'd have theoretically 1St(underdrive),2nd(OD),3rd(Double OD). Or have I forgotten or omitted something in the idea?

thoughts?

FYI i have a few other moding ideas on paper but, figured this was a goood start as any.

(yeah there's the ole saying, "Throw enough $$$ at it and you can do anything." But,I'm trying to do this frugally and with stuff on the shelf as well as thinkoutside the box here)

the problem with using a automatic transmisson in that application. is under load if the solenoid did manage to disingage 1st gear it would never under load engage to 2nd gear o/d though could work with standard trans.

what about a clutch?

What if i had a clutch assmbly that was inbetween the ole 3 spd and the output of the auto?

yes it'dneed a "clutch actuation arm in the cab.... sooo the firewall has to have the metal already welded inplacefor a slight swapping of pedal parts eh????

heck I've already converted a subaru from auto to stick...twice(long story). There have been many threads i've seen over the years of converting other cars from auto's to clutch setups....
