Hi guys I'm a transmission specialist from NSW thought I should share this with you guys. If you didn't know the a340 has a bit of a Lubrication issue and causes it to destroy the bearings in the torque converter. This causes you to blow the converter and the gear box especially bad when hauling weight. A new kit has come out to slightly raise the pressure so it doesn't shift to h**** but fixes the sloppy shifts this transmissions have especially when cold and also opens the oil feeds up to get the lube up to the pump and torque converter more. 9 out of 10 hilux 4 speeds I build need a new converter or costly repairs to the converter. It is getting very hard to find used ones as well and a new converter is around $1200 and really adds to the rebuild bill if you are unfortunate enough for this to happen to you. So heads up the kit is just over $100 a new filter while the pan is off and a external transmission cooler could save you thousands. Everyone I have fitted have been happy with the out come. Cheers guys
