auzzam Posted December 7, 2019 Share Posted December 7, 2019 Hi guys, I'm currently have an auto TT that needs to gearbox seals done. This has driven me to weigh out my options if I was to keep the car long term. I've been looking into the cd009 and have found a kit, but just wanted some opinions as there's a few points I don't really understand well. 1) the internet suggests that paired with the AUTO TT diff, first and second gear will be short. What does this mean in reality? And should I factor in getting a gs400 diff which seems to match better. I don't want to go through the whole conversion cost and find the car undriveable due to short gears. 2) the kit I'm looking at comes with LHD pedals, could this be modified to work on a RHD car? The seller suggests there have been supras out there that have used RHD pedals on LHD so in theory to him it should work. One of the main drivers is it would potentially future proof my car if I want to go single power. Let me know your thoughts! Thanks Quote Link to comment Share on other sites More sharing options...
Ric Posted December 7, 2019 Share Posted December 7, 2019 I had a seal replaced on my gearbox done by James Hart at Performance by Hart, price wasnt bad at all tbf. Give him a call and see what he can do for you. Quote Link to comment Share on other sites More sharing options...
Noz Posted December 7, 2019 Share Posted December 7, 2019 If I was auto. I'd consider the DSG system whifbitz provide. Quote Link to comment Share on other sites More sharing options...
AC93 Posted December 7, 2019 Share Posted December 7, 2019 Do you want to convert to manual? You can buy a replacement auto box for a few hundred quid... Or go built auto from SRD. If I was going manual again I'd just get the T56 or R154 Quote Link to comment Share on other sites More sharing options...

The dsg one is nice, but out of budget due to needing the syvecs install too. Quote Link to comment Share on other sites More sharing options...
Noz Posted December 8, 2019 Share Posted December 8, 2019 R154 I can confirm is nice. It's a bit clunky however. Considering rebuilding mine. Always the worry not to trash it though. Quote Link to comment Share on other sites More sharing options...
auzzam Posted December 8, 2019 Author Share Posted December 8, 2019 Anyone have thoughts around my diff question - really want to make sure the car isn't undriveable. It's only bpu so not crazy power Quote Link to comment Share on other sites More sharing options...
P_Bazz Posted December 10, 2019 Share Posted December 10, 2019 The 3.7 auto diff ratio is suitable as the Nismo 370Z is also paired with a similar diff and the same gearbox. However the Nismo is a high revving NA which needs the shorter ratios due to a lack of torque. A BPU Supra does not need such short gears because it would just be spinning the wheels. The normal Zeds were fitted with a 3.5 ratio diff. With a 3.2 TT6 diff the CD009 is the same as the Getrag as far as gearing goes. If you go down the CD009 route I would buy the automatic bellhouse adapter style kit, even more so if you already have the auto now. The plate adapter style does work and has the pro that you do not have to cut the bellhouse from the CD009 the con is that it just barely fits the tunnel and can only be installed/removed with the engine out of the car, Quote Link to comment Share on other sites More sharing options...

Could see this becoming a pain in the future. The kit I was looking at was fitted to a sc300 2jz-gte and was an adaptor style. The seller mentioned he did not need to remove engine - but he did have to knock the tunnel. Do you think it would be the same case on the supra?

Style Posted December 10, 2019 Share Posted December 10, 2019 I'm pretty sure Tavarish went CD009 on his build which he documented on YouTube. Might give you an idea of what you're up against. Quote Link to comment Share on other sites More sharing options...
basch32 Posted December 10, 2019 Share Posted December 10, 2019 I have as new V160 gearbox wrapped in the garage if you are interested, however its not cheap as I would eb looking to recoup the cost I spent on it. However would be cheaper than a conversion I would assume but you would not have the replacement option years down the line. But if you can drive and maintain it shouldnt be an issue Quote Link to comment Share on other sites More sharing options...

I have not bashed the tunnel as it fits without having to do that (standard MT tunnel). I did however remove most of the protruding parts of the gearbox with a grinder, especially around the front of the bellhouse. I do not see my transmission coming off while in the car as you can't reach the fasteners on top or get them out even with the gearbox tilting backwards. The size difference between a W58 and CD009 is huge. Quote Link to comment Share on other sites More sharing options...
