irokin Posted January 17, 2006 Report Posted January 17, 2006 Ive found (with my gearbox at least) that if I stop from ~100kmph in 4th or 5th (usually 5th) and just clutch in and stop (if the phones ringing I don't bother down shifting, its faster just to stop), the selector forks jam in gear and I can't change gears until I'm doing ~40kmph. Now as you can imagine taking off in 5th is a real bastard and hard on the clutch. I'm not sure if this is just my gearbox being crap, or its a design flaw in the early T50s. It happened again today, and Id say my box is pretty well rooted this time. 2nd gear syncro works for up shifts but not down shifts now. 5th gear syncro has a metalic grinding noise (def syncro) but still works fine. Reverse likes to select forward and reverse (doing a russel ingall in the chase) and wont release without a little coaxing. Id say its probably gearbox change weekend for me (ahh what a carnt!!). Ive got a spare box but I'm interested to know if anyone with a T50 (particularly early celica boxes) has a similar problem... Heres hoping the gearbox doesnt lockup on the highway doing 100kmph....

Felix Posted January 17, 2006 Report Posted January 17, 2006 i think it is just fnackered. how long since it was last rebuilt (if ever)? maybe throw some ATF in it to get a few more weeks/months out of it... :cool: Quote

Seems like your clutch is not disconnecting correctly. T-50 is not a crappy box and it takes a lot abuse, when it isnt allready broken or needing for maitenance. If example your synchro is worn out because of over 300 000km on box or with some stupid usage, it's no way fault of g-box :cool: Quote
irokin Posted January 17, 2006 Author Report Posted January 17, 2006 I doubt it was ever rebuilt. Clutch is disengaging properly. Doesnt try to roll anywhere when its idling in gear with the clutch in (and its a very easy car to move). Its probably just tired like you said. Its done this about 3 times in 5th now but today was the first time it jammed in 4th!! None of the syncros worked for about 500m and I was having to either double clutch or shift clutchless (hehe I drive a dogbox truck at work so Ive got some experience) It not going into reverse too was rather odd....its never had any issues with reverse before. Ugh...I don't wanna change gearboxs...anyone wanna buy a shitbox celica?? new car time... Quote
Medicine_Man Posted January 17, 2006 Report Posted January 17, 2006 Sounds like I'm not the only one changing a gearbox this weekend :cool: Quote

I meant MY crappy gearbox. I was just wondering if other T50 drivers have experienced the same problem (although I'm probably the only one who has stopped from high speed without downshifting :cool: ) I must admit its put up with alot of shit from me...I accually kinda suprised its lasted as long as it has. Sounds like I'm not the only one changing a gearbox this weekend :) Wooo!! gearbox party!!! Quote
love ke70 Posted January 17, 2006 Report Posted January 17, 2006 just an idea, why not bung it into neutral when stopping rather than downshifting, i tend to knock my car into neutral as i start braking whenever I'm coming to a complete stop, more work for the brakes as there is no engine braking but it might stop your problem of jamming in gear no experience with t-50's just my k50 which crunches second on some occasions and first gives a metallic ringing when tryna go 3rd-->1st at ~30 k's. always amusing, i just blame the L plates :cool: Quote
irokin Posted January 18, 2006 Author Report Posted January 18, 2006 Well...the box is fine again. Took off thismorning and it was no different to any other morning. Syncros were fine (2nd is a bit tricky until it warms up) didnt grab 2 gears at once, just drove like it would on any other morning. got me buggered? Quote
Tiger Posted January 18, 2006 Report Posted January 18, 2006 Just change over the Silvia driveline into the Celica.. You'll be moving then :cool: I'm imagining you don't wanna spend the bucks to grab another T50, do you? I'd say it's just an old box that's finally taking it's toll. Quote
TRD ke70 Posted January 21, 2006 Report Posted January 21, 2006 never struck that in a T-50, but i'd say it's a slector problem, most likely worn out. there is a small nylon bush that sits on the bottom of the gearstick, if that's worn it'll give simular problems. there's also what they call "dee tents" which stop you shifting 2 gears at once and if they haven't been put back in right they can cause problems. the early T-50's do have smaller bearings and a smaller out put shaft size. the AE86 has bigger needle roller bearings and larger shaft sizes. but both boxes don't really have any common problems.

muller Posted January 21, 2006 Report Posted January 21, 2006 g-boxes can be so annoying when they start going on the blink. :) Quote
