T50 Poping out of Gear
Bit of a strange one, just done the clutch in the car, & replaced the Gearbox Oil etc, went for a trash tonight & the box was throwing gears right from the start, 1st Mostly then 2nd, The tunnel seemed to get very hot.
Then all of a sudden this strange episode stopped & the car drove well for another hour. Sounds stupid but would the gearbox oil effect this at all, I put 80w in. Surely its a wore syncro that is the cause of this problem but why would it stop?
was it throwing gears before you changed your clutch and gearbox oil?
also how much oil did you put in the box and where did you fill it from?
when you took the selector out did you make sure it went in with bush on?

the only thing i can think of, maybe if you messed with either the spigot bearing, (in the crank) or the release bearing carrier guide (the thing the input shaft goes through).. the spacer behind there.
seeing as you did the clutch maybe you replaced the spigot bearing.. didnt push it in far enough, and it was putting pressure on input shaft.
or you left the spacer out, after replacing the seal?
either of those things could maybe miss align the clusters...?
guessing. just suggestions cos you did the clutch.
Ok, I left the release bearing on (felt good) as it was very tight & I had basic tools & little time, didnt mess with anything else. But I did for the 1st time fill the box from the top after I had bolted everything up, it was a time thing once again. about 1.8 Ltrs Wasnt throwing gears & isnt now!
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.
ok
i have filled a t50 from the top before and found it didn't drain properly into the box straight away but took awhile to drain into the main body of the box
i pulled apart a t50 not long ago andwhile there is a drain from the rear to the main shell the drain is very small.
more than likely when you first drove it there was fuck all oil in the box and as you drove it it drained down.
my theory anyway
It took the oil very quickly, but yes thats a definate possibility.
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.
a previous t50 of mine started to do this, but mine only did it in 2nd, and when i pulled it apart, the splines on the 2nd gear were severy rounded, so it couldnt stay selecteddoesnt sound like this is ur problem though.
