na - stuck in 3rd trying to dissassemble turret - help please
So my 91 na which I bought as a non runner is stuck in 3rd (based on lever position and I can barely just pull off in 3rd if it was 5th I dont think I could pull off) clutch works as normal but just cant change gears
I have tried the detent spring and ball removal on all the detents i could get to - no luck
I have tried the reverse light switch jiggle - no luck
I have tracked the problem down to something more serious than those simple fixes - its either in the box itself or the shift rod from the turret
The previous monkey that worked on the car clearly forced the shifter against the turret hole on the body as they clearly removed and installed the engine and gearbox as a unit - with leaving the shifter in place - so something has been forced - plenty scratches and nicks and obviously excess force used
The innards of the turret wont disassemble now - I have got the box out the car and the turret halfway disassembled - but I cant get the roll pin out as its stuck in gear and there isnt enough space on the other side of the sifter pivot block for the roll pin to knock through - I have knocked it halfway through and its up against the turret casing on the other side - any ideas how to remove this half knocked through roll pin ? thats now butted against the turret housing.
I have tried screwing a self tapping screw in and pulling on that - no luck
I am thinking of taking a small drill all the way through the roll pin and drilling a small hole say 2mm all the way through and popping out the other side of the turret and then drilling a bigger hole back in to then knock the roll pin through, and then plug the hole with jb weld or similiar
Anyone have any other ideas before I swiss cheese this turret ?
Parts are scarce for Miata transmission in my part of the world - any help and advise welcomed
