Max power of JZX100 4-speed automatic transmission
Posted 30 April 2011 - 07:10 PM
I've been searching the forums but to my surprice I can't seem to find any reports on how much power a stock 1999 Chaser four speed automatic transmission will hold.
Does anyone know?
I'm contemplating using it in my Supra. I know the stock JZA70 transmission is fairly good and better than the JZA80 n/a transmission, but I'd like to know how much the JZX100 transmission usually can handle.

a jzx100 is just a more complicated version of a jzx90/jzz30/jza70 auto
there is 3 main auto types to consider
3 solenoid , kick down cable a340/a341 which is jzx90 /jzz30 / jza70 ( these still hae minor diffences beween but essentially the same box )
5 solenoid , non kick down cable a34x jzx100
5 soleniod , non kick down cable a34x jza80/jzs147 , which have an extra clutch than jzx100 and a diffent valve body too
you say how much power will they handle , well dead stock id be guessing but up to 280-300 rwkw would have them burning clutch packs on gear changes
put a mv autos shift kit into them and a decent trans cooler and u can save them from death at 280-300 rwkw
or spend a bit more at mv's and they can build em to handle 400rwkw and 9s down the drags
if you wanna run the jzx100 box , u will need to run a 3 soleniod valve body , addd kick down cable , and then there is also differences in the speedo drives /sensors and out puts
my sugestion is build up the box you have with a shift kit and trans cooler , and if yours is already dead , find the same box and fit the safety devices mentioned
hope this helps a bit

So that is why the JZX100 transmission is interesting. Will it hold as much power as the JZA80 TT autobox?

So I have gotten a JZA80 n/a gearbox. But they are not that strong. So I was wondering how the stock JZX100 autobox compares to the JZA80 n/a box. I can get a fairly cheap JZX100 autobox so if it is stronger than the JZA80 na box I'll get it. The JZA80 has the 2JZGE engine and that is only 225 hp. So I thought since the chaser 1JZ-VVTI with turbo is 280 the autobox might be stronger too.
