    A friend of mine had a late model Commodore SS, manual. It would not go into gear properly. The Holden dealer gave a quote on a gearbox rebuid, so my friend just parked it for a month. Then decided to have a look. Turns out there were a few rocks just sitting on top of the gear stick, problem fixed. I got all proud and told him "that could never happen on a Toyota, because there would be a rubber boot there or something"... but you never know.

    I say, if the problem has fixed itself, it must have been a stone or metal burr somewhere preventing full gear selection.

    ok

    i just had this problem.... it was the bearings in the box going cause the syncro's were worn.

    I had my entire box rebuilt for $800..... not cheap. but full new internals and i now have a basically new box.

    Rather than spend $800 on a g.box that will most probably fail after multiple thrashings, you could find a steel case celica box,(can be had for reasonable money), an adapter plate and you will have a half decent box that will resist most attempts to destroy it, or you could go all out and use a supra box, big$$$$, i am pretty certain you would be able to achieve a celica steel case conversion for $800 maybe less, pretty sure Dave at AJPS sells or used to sell these adapter plates. I hope this helps mate
    cheers.

    i would have done that, but time was off the essence.

    this was a 4 day fix..... and they had to get parts from melbourne.

    otherwise if i had known how bad i would have just gone supra box.

    Someone in Japan had modded my T50 to make this easier. I got a 92000klm T50 from a halfcut and it had had the drain from the shifter enlarged to allow the thing to be filled from the top in quick time. Works awesome. Although Ive never driven Immediately after filling it, soonest was around 20 minutes after, but it presented no problems. My old worn, ADm T50 used to slip out of third once in a blue moon.

    Have a spare T50 of unknown quality so no panic, when I get a bit more power I will start the look out for an upgrade. A few guys I know in the Rally scene all got rid of their W-series in 86s because they didnt like the ratios, went for a Ford box with bell house adpt.

    its probs cause you snap second every lap man!!

    just get a heap of speed before it and you'll never have to down shift for that tight corner, does your handbrake work any good? would make it heaps easier aswel (mine doesnt = more fun and challenging ahhahaha)

    I think Slydar could have a couple of very valid points there, either way sounds like box out time again.If you have not installed the spigot bearing deep enough it will indeed place pressure on the point where the input shaft and the mainshaft connect although if this was happening to any great degree you would not get any gears when it is running, it would just grind and refuse to go into gear, same thing happens if the spigot bearing seizes. When you keep snapping it into second your cluster bearings will wear prematurely, and when you select second gear the cluster actually moves away from the mainshaft slightly and the resulting misallignment causes it to pop out of gear.
    Clearances and shims are very important in a gearbox and losing them or getting clearances wrong can cause you shitloads of grief and possibly be expensive.
