Hi all,
I've just had a 6-speed gearbox fitted into my 96 car......small problem!!!
I had the box rebuilt with the twin-splin shaft to use the ealier clutch, had the NSX-R final drive and a lightweight Jun flywheel for good measure also. New bearings & seals all fitted to the box as well.....
The gearbox was re-built by a reputable shop over here in the UK who also work on the NSX racecar some have you may have seen on here with the paddle-shift sequential gearbox...Was advised all the selector forks, synchros & gears were in good condition with no concerns requiring replacement.....
So anyway the point, gearbox fitted, all forward gears fine but reverse has a problem. The gearbox goes into reverse ok and if I slip the clutch I can reverse but once the clutch pedal if let fully out the box jumps out of reverse abruptly. Basically any load in reverse and boom, reverse is gone.....
The gearbox itself was fitted by an NSX dealership. They mentioned it popped out of gear once but put it down to their driving....Just to cover the bases the car was put back on the ramp to check the cables. It was found that the cables were correctly adjusted and the gear box selector could travel no further even if the cable length was shortened a little.
THe reverse lockout solenoid has not been wired up yet but my understanding anyway is the default with no power to the solenoid is to allow reverse to be engaged with the box does anyway, it just jumps out on load....
It's all a bit of a bummer as it looks like the box will have to come of the car and be opened up again which means all the time so far is effectively wasted :-(
My question really to any of those who know the gearboxes well is, ahead of it being removed, do you have any suggestions as to what would cause this situation?
Also just to confirm for those every considering this mod, my 96 car with the earlier power steering does not flag up the EPS fail with the 4.23 final drive as I think it does from 97 onwards....
Thanks,
Gary
