Full syncros in a IIa trans?

[BackInA88]

"Full syncros in a IIa trans?"

Someone mentioned doing this in another thread instead of swapping to a Series III trans.
I like this idea. Since I need to replaces seals and such already.

Are there kits available to do this or do I have to just start ordering the parts I think I need? If the later is the case I would just get a rebuilt Series III trans. As I am not going to guess.

Thanks,
Steve

I have the syncro-less IIa tranny with no problems.

I can double-clutch, but have found it does not shift any easier than if I don't, so most of the time I don't bother. I have also found that if you 'throw' it into gear, rather than 'baby' it into gear, it tends to grind less.

If the revs are "right" and the technique is firm, but not abusive, it goes in easily, if not, well we all know that sound...

I suppose if this is your only manual shift vehicle, it might be a problem to get the technique just right. Personally, I think double-clutching has become a lost art, and should be preserved for our grand-children!

Ref the synchro tranny, RN sells either a "bolt in" fully synchro trans with t box (607125RS) for $2157.85, or a Ser III trans/t.box (RNC495)for $1895.00.
You could elect to swap your bell housing/clutch throw out from your IIa to the Series III gearbox, thus you would have all the advantages from the Series III, full synchro and better reverse gear. All avail from our hosts.

Les,

Are the Series III boxes RN offers the later model heavier duty cases?
How much extra for the bell housing/clutch throw out to do the swap?
Any core deposits on either set up?
The website is a little lite on details.
Been looking into doing a R380 swap as well.
Never got the RN catalog I ordered weeks ago, been buying straight off the site.
You can email me at slouzon@gmail.com if you prefer.

Thanks

If you swap in a series 3 gearbox you get a lower 1st gear too which gives you a great off road crawler gear.

I think the difference is only .08 between the IIa and III tranny 1st gear. it is a difference but not really huge.

I don't really think there is a significant advantage to upgrading to an all synchro box unless the original parts you need are no longer available.

Absolutely. I still double-de-clutch my SIII box out of habit and because it's smoother if you get it right. Also useful if your master or slave clutch cylinder goes belly-up and you need to limp home without a clutch at all. Amazing how easy this is if you get the revs right.

The only reason you absolutely need a clutch is to start from a standstill. I find that shifting my Rovers (non-synchro 1st +2nd IIA's) is easiest without the clutch. Once you get the timing right (it might take a few times) the rover slips right into gear with no grinding at all. Downshifting does take a bit more practice with the non-synchro gears but is no problem downshifting into 3rd.

Not much difference for 1st gear but reverse! WOW!

I can either upgrade it now while I still have a good working 2a box or after my wife wipes out the 2nd gear and have to replace it and have a boat anchor laying in my garage.

Thanks for your input guys.

Ha! yeah that is apparently true, too bad that wasn't the 1st gear...
