Milo500 Posted October 27, 2017 Share Posted October 27, 2017 (edited) Hi guys, I know there are alot of threads about manual converting, however this is slightly different. So the car is running 500, gte engine and single converted. The auto box has two large oil coolers, and has never missed a beat...until now (I think). When on hi boost it feels like the tc is slipping (almost feels like a clutch slip) but then it stops slipping for about half a second and then slips again, over and over...when driving normally it's perfect to drive as always and on low boost its not as bad as hi boost. Now does this sound like the box, the converter, or even the diff? Or does it sound like it needs the box filter and fluid changing? If it turns out the box or converter is knackered, then what shall be done? This is where I am asking for opinions. Do I get a better tc possibly high stall. Build the box. Manual convert it, not a getrag supra 6 speed (I'm not rich haha). M3 320 box, cheaper bmw box, 350z box? I have nothing against autos, and don'y mind people always being like...ohh it's an auto supra, or when are you manual converting it. Just looking at the best option. What do people recommned and what is the cheapest, as I will be doing all the work myself. Looking to do it, not on the cheap, but not looking at spending like 5k Thanks guys.

Never understood the point of manuals when you can just put it in D and go Yea I agree haha, however I don't drive it every day now, and if it's going to cost me 1-2k to put a good tc or auto box build in it, it might just be worth spending the same/bit more and making it manual...however it depends what the problem is to start with tbf Quote Link to comment Share on other sites More sharing options...
evinX Posted October 27, 2017 Share Posted October 27, 2017 I doubt itll cost near 2k. Join the A340E group by DavidP theres tonnes of info. As i recall you can beef the autobox to take stress. A second hand autobox shouldnt cost ya more than 2-300 Quote Link to comment Share on other sites More sharing options...
Hitbox Junkie Posted October 28, 2017 Share Posted October 28, 2017 Its all personal preference. Ive a manual but id love a auto. Ive become lazy. Manual is great wjth reguards to kicking the back end out. If i were to go auto then id be looking at burnas new flappy paddle range rover kit that he deveolped himself with help.of other forum members. Or id be going lexus 7speed auto by SRD or bmw by wifblitz. 350z manual or an t56 (in the end will cost as much as the oem 6speed but the boxes are cheaper.)

Chris Wilson Posted October 28, 2017 Share Posted October 28, 2017 It sounds like the gearbox itself, screaming for mercy in its death throws. Is the fluid discoloured and smelly? If not it probably soon will be, it won't last long like that! Quote Link to comment Share on other sites More sharing options...

If not it probably soon will be, it won't last long like that! What can be done if it is the box itself? I've done alot with manual boxes in terms of uprating them, but not too sure with autos. As if it was the tc I would probs just get a decent aftermarket one or a higher stall. Also where is this forum from DavidP for the a340e? Thanks for the feedback guys Quote Link to comment Share on other sites More sharing options...

supradanturbo Posted November 2, 2017 Share Posted November 2, 2017 If you put a higher stall in it. It will 100 percent finish it off if it's already slipping. The higher stall will make a lot more heat. Quote Link to comment Share on other sites More sharing options...

mellonman Posted November 4, 2017 Share Posted November 4, 2017 Yes but in america its a popular conversion for the drag racers Quote Link to comment Share on other sites More sharing options...
Milo500 Posted November 4, 2017 Author Share Posted November 4, 2017 I have looked through all the forums about swapping to a manual. However none of them actually state all the components needed for tge conversion. I am looking at the e36 m3 6 speed manual gearbox. Is there are other conversion kits other than the expensive abc kit? Quote Link to comment Share on other sites More sharing options...
