Pig Posted June 22, 2011 Share Posted June 22, 2011 It's been coming for a little while but 3rd gear is now done and dusted. When racing I can't change up without lots of grinding and I can't get it in at all going down (just grinds). Driving normally, you wouldn't know anything was wrongs with it. Please can I request you EXPERIENCED advice. P.s my budget will not stretch to a new one at 6k + Thanks Jon Quote Link to comment Share on other sites More sharing options...
JamieP Posted June 22, 2011 Share Posted June 22, 2011 From what dude and Ryan have said in the past rebuilds dont seem worth while, can be very expensive. Best bet is to try and pick up a 6 speed kit and sell all the other bits you dont need mate, i would buy a TT6 diff from you;) Quote Link to comment Share on other sites More sharing options...
Pig Posted June 22, 2011 Author Share Posted June 22, 2011 When it started going wrong, I knew that I would have to get involved with bull shit getting hold of one of these gear boxes. It wasn't that fact that the car was breaking or the cost, just can't be bothered with the hunting. My tech knowledge is rubbish, is it simple to replace a syncro if that's all that wrong? As at the moment I still have all gears, what went when you did your gear box Jamie? Quote Link to comment Share on other sites More sharing options...
dude Posted June 22, 2011 Share Posted June 22, 2011 Not easy to work on and parts are very very expensive, I have a new box only done dyno time for 4K or a recon for 2K. Quote Link to comment Share on other sites More sharing options...

Homer Posted June 22, 2011 Share Posted June 22, 2011 There are some places that can rebuild these boxes, but they are few and far between. It sounds like the 3rd gear syncro has gone, this is suppoedly something that was uprated in the v161. If you need I can find details of the person that did the partial rebuild on Ian C's box some year ago. They are based in Watford. I suppose it depends how much you want rebuilt - i.e just the specific issue resolved or the entire box rebuilt. After speaking to Ryan about his one, it seems that a complete rebuild is not financially viable and would be cheaper to buy a 2nd hand one.

JamieP Posted June 22, 2011 Share Posted June 22, 2011 what went when you did your gear box Jamie? In the old red car that was an easy fix, clutch got stuck on, turned out i had twisted the main shaft, some place in MK fixed it for £250.

dude Posted June 22, 2011 Share Posted June 22, 2011 The gear cluster will have the little teeth the syncro needs to lock onto, both of these will be warn, the whole gear will need to be replaced, only a couple of really bad missed shifts can do this, hence I will be changing mine this winter to a stronger 5 speed.

sdistc Posted June 22, 2011 Share Posted June 22, 2011 One of my best mates rebuilt his 6 speed with a press and OEM parts. It wasn't a huge job, but the parts (as with all Toyota) were relatively expensive. Quote Link to comment Share on other sites More sharing options...

You also need special tools otherwise there is a risk of breaking stuff. Quote Link to comment Share on other sites More sharing options...
Pig Posted June 22, 2011 Author Share Posted June 22, 2011 I have a place locally that I may speak to as they seem good. (only looking for partial) then I might ask you to have a look homer. Missed gears....up or down? I have had loads of both I'll also have a look out for a second hand one...2 & 4k are both out of my budget at the mo as I have just renewed all my single parts and exhaust etc. Quote Link to comment Share on other sites More sharing options...

Yeah, I unintentionally underemphasised the process - my friend is a mechanical engineer, and had the use of a gearbox builder's experience plus some tools for driveshaft building. And, as you've said, the wrong parts were sent at least once. I think, though, that the balance of experiences posted show that rebuilds aren't economically viable - and I wasn't suggesting they were, just that you could potentially save costs if you were mechanically competent and/or had some motorsport contacts.

Thomas.B Posted June 22, 2011 Share Posted June 22, 2011 Cant you just find the needed parts from other makers? Have done this to motorcykle gearboxes and its not very hard, but you do need special tools. Quote Link to comment Share on other sites More sharing options...
Ian C Posted June 22, 2011 Share Posted June 22, 2011 I lunched 5th gear a few years ago by cocking up a full bore upshift. Mark (oh how we miss him) at Phoenix in Watford got it sorted out for me. He took it to a place that I don't have the name of, which is a crying shame, as it cost me all of £300 to get it fixed. The box has been perfect for years since then, so they can be fixed and it can be cost effective. I must add that the Getrag 6 speed is a 4 speed box with a 5th/6th module on the front of it, and 5th gear is the first one you come across, so it was the 'easiest' to do. There is a mountain of special one-off service tools needed to pull the blighters apart, so it'll get more expensive for 3rd, but only for labour and non-reusable parts. Speaking of Toyota sending the wrong bit, this happened to my rebuild, took three attempts to get the right particular bearing. However, it was only a delay of about 6 days, 2 days each time to get the part shipped from Belgium, so it's not the end of the world. Really it just comes down to trusting someone to rebuild such a complex 'box. If Homer can get the name of the guy who sorted mine out, it'd be a major major plus to us all, as they've got previous form on doing the work and doing it well. There is a full parts list in a zipfile somewhere on this site, which would help with any rebuild shenanigans. -Ian Quote Link to comment Share on other sites More sharing options...
dude Posted June 23, 2011 Share Posted June 23, 2011 Tommy who works for me has rebuilt 2 and I know of another guy who does em all the time (very similar to a skyline box) Quote Link to comment Share on other sites More sharing options...

Pig Posted November 18, 2012 Author Share Posted November 18, 2012 The gearbox is still pretty shagged but I haven't done anything about it yet. Quote Link to comment Share on other sites More sharing options...
