Mnaual Gearbox Conversion
Mnaual Gearbox Conversion
(OP)
Hi,
I would like to be able to modify a 5 speed manual gear box so only 2nd and 3rd are to be used for forward movement as well as keeping reverse. The desired movement for the change would be as simple as it normally would be for changing from 3rd to 4th, the clutch would also need to remain.
Any information greatly appreciated
Thanks
Grant

Only ever move gear lever to 2nd or 3rd or neutral or reverse positions.
To go one step further place an obstacle in the way of the lever so that it can only move to those positions.

Engage the gear forward of the selector.
Engage none.
Engage the gear behind the selector.
The H pattern chooses which selector you are moving, so lever far left hooks the 1/2 selector, lever middle hooks 3/4 selector, lever right hooks a two position selector that can engage 5th or none. past the reverse lock out then further over hooks the reverse selector which may actually slide a gear on a splined shaft rather than engaging syncro cones and dogs on the sides of the gears on the mainshaft.
Try to get an old non repairable gear box from the scrappers and pull it to pieces and see how the selectors main shaft, lay shaft and cluster gears work together.

At any rate as others have said you need to address the each gear selector for your 'H' pattern.
I don't know anything but the people that do.

That could work and is quite an innovative thought.

I think it would be a lot simpler, no need for modification...
RE: Mnaual Gearbox Conversion
Can your application tolerate that much gear ratio spacing (or a loose enough torque converter to crutch it)?
Was your original plan of using 2nd and 3rd in a conventional 5-speed manual intended as a way of getting around the rather large "gap" between 1st and 2nd that's common to most such gearboxes?

Powerglides also have an optional taller first gear. 1.7 something:1 Still a short gear when the only other in the box is 1:1
