It will be a gearbox out job unfortunately and you will have to at least split the front off it. If it still selects all 4 forward gears (it will lock the gearbox up if you pop the clutch) but is stuck in reverse then it has slipped out of the gate while coming out of reverse. It may have a worn rod end that may have caused this. Or if it is stuck in reverse and selects no other gear and the gearstick flops around like a cock in a sock then it has jumped out of the gate altogether. But if the gearshift moves nowhere but reverse and it's stuck then there will be something bent somewhere.

The other box's will be no less unknown than the 4 speed .

Yeah it seems to select the other gears but when i try and turn it over it just like moans and wont turn over unless i put the clutch in.

That groaning is 'the old 2 gears at once trick eh' and there is only one thing that you can do about it. rip the gearbox out and separate the front bell housing from the sandwich plate. But try to not separate the rear case. With the selector finger still in the gate you may not be able to get the rear casing off anyway. Although it won't hurt to attempt to take the rear housing off as it would certainly make life easier. A bit of sealant after you get the thing into neutral and you are good to go. Just time.

this was one of mine that was all ood when i shipped it. the carboard was over the input shaft and then wrapped in glad wrap.

was selecting all gears fine when shipped and we have been through this on phone and via pm.

i thought your neightbour was going to look at it for you?

These gearboxes are extremly hardy stuff. I would aslo say open it up check before you go all awal on us. Good luck

Quote:Well thats cause it seemed fine and as Revhead said it can feel like its selecting all gears but when you try to start it it will be jammed. The input shaft was sticking through the thin cardboard when it arrived. Wasnt looking to attack you mik i am looking for a solution. As you can imagine im peeved off but with the whole saga not just the jammed box. Its out with motor and box and get me TRX 5 speed box checked out if all good get tail shaft shortened a bit more and back in she goes. No point cryin over stuffed gearboxes there's plenty around ay.

it will be all worth it

Don't give up at this late stage, your almost across the line.
You are not far off being able to appreciate all the work you have put in.

I thought the TRX boxes are longer?

I have done this conversion (with stanza 5spd) and can only reiterate that it is all worth it once done
cheers

Thanks Heaps Fellas. Yeah TRX box is definitely longer going to make some measurements as im sure the mounts (cross member) are in the same place.So will check that and if shifter is going to be much further back. May just look for another stanza 4 or 5 speed box.

Stanza gearbox is probably 26.3 inches in length (same as automatic transmission length). This is the 'stumpy'. Most other 63-series are longer.
