R100 Posted May 18, 2006 Share Posted May 18, 2006 Looking at fitting an auto to a project im building. I need a good strong box capible of handeling 400 + HP It also needs to have a removable bellhousing. Ive been looking at Turbo 350 transmissions, but they all seen to come with the bellhousing incorperated. Powerglide is another option but id like more than 2 gears. C4 transmissions are again another option, who knows whats better ? What type has the most avalible parts, whats cheaper to rebuild, whats stronger etc etc. This may not be the site to ask about them, but im not sure where else to go. Any help would be appreciated. Thanks in advance Quote Link to comment Share on other sites More sharing options...
crazy_rich Posted May 19, 2006 Share Posted May 19, 2006 dude, ya can have the auto trans from behind my lexus v8, they are a dime a doz, real strong, easily shift kitted, removable bellhousing etc. and they arent worth anything because they never need replacing.

v3k Posted May 19, 2006 Share Posted May 19, 2006 400+ hp? Wouldnt you be after a C6? (might be overkill) but I think there is a fair amount of drivetrain loss unless you sort out a decent stall convertor. Quote Link to comment Share on other sites More sharing options...
RT Posted May 19, 2006 Share Posted May 19, 2006 I know plenty of people putting 400bhp though a C4.. they are fuckin strong. But yeah you could go a C6.. but there's a weight penality. But good for 600odd + heaps of aftermarket bits for these boxes. Whats it going in? Quote Link to comment Share on other sites More sharing options...

R100 Posted May 20, 2006 Author Share Posted May 20, 2006 What its going in is top secret at the moment, but after a few calculations i need a box to handle 600-800 HP and between 1600 to 2000 NM of torque. Im not familia with a C6 trans, but i have heard of a C4, ive also been told a C4 can be modified to handle alot of power. People have also been saying a Power glide is a better option. I will be fitting a 2000 to 3000 rpm stall converter. Car will be used for the street. Quote Link to comment Share on other sites More sharing options...

You are building a ferocious Diesel arent you! 2000 rpm stall converter? for street use, just a word of warning about that, if you are doing 60kph at 1800rpm with a 2000rpm stall converter the convertor 'slip' will be constantly kicking in and out and you will burn it out REALLY quickly. Something to take into account, if you are planning on using said beast for driving around town/open road and not just flying up the 1/4 then you really need to get talking to an automatic tranny specialist, not just a preformance shop dude. Anyway, I know bugger all about it - I just happened to be reading about how stall convertors work etc and that was something I came across and thought you might like/need to know....

R100 Posted May 21, 2006 Author Share Posted May 21, 2006 Makes good sence what you say about if im running around at 1800 RPM, its something i did not think about and will take into consideration. Its going to be petrol powered, no deisel here ! Quote Link to comment Share on other sites More sharing options...
danger Posted May 22, 2006 Share Posted May 22, 2006 Haha go the 3 speed Jatco... Actually I think they can be built to handle power funnily enough. Quote Link to comment Share on other sites More sharing options...
SYKOV6 Posted May 25, 2006 Share Posted May 25, 2006 c4\c6 \power glide best choices c4 nice and lite bolt on bell housing \small phyisical size and able to be modded to handle insane hp. same with c6 just abit bigger and heavier. P/G good and well proven behind mega hp v8s still will require a fair amount of mods for your usage. hi stalls are sweet on the street they dont slip below the said stall speed. they only slip when u mash the loud pedal then they slip till the engine gets to its powerband and hit hard. i had a 3000 stall in the corty and it was sweet. good fun at lights. DONT buy a second hand one or and off the shelf item they should always be custom made for your engine mods/gearbox ratios and diff ratio. torque convertor engineering in pukekohe did mine worked perfectly and about 500 bucks. the only thing u need is a good aftermarket trans cooler as they do run hotter than stock Quote Link to comment Share on other sites More sharing options...
