The answer to all those questions is a few pages back in this thread.
The 4bdx to H42/H55F adapter is in the works but it is not going to happen over night.
euclid said:This is all internet rumor, but the A440 was evidently used in a small people mover bus produced by Toyota for Japan. Rumor is that it was used for years with great success. They had some on the shelf, and decided to give the US an auto 60: the 62. The tranny worked great in high torque, low RPM situations like the bus. The trouble with so many of them dying is that the heat of 65 MPH/2700 rpm for thousands of miles kills them.
Does that auto not have a lockup?
Because with a lockup, the TC is no longer creating heat and the story falls apart.
Add to your wish list 3rd and 4th lockup, and the option of a push button lockup torque converter - that's what I have in mine.
The valve body mod does increase line pressures a tiny bit with the valve body, but not much. See here
Locks up at 54MPG in stock form.
As I understand it, the torque converter doesn't really create heat, it increases the efficiency of the use of the engine's power by getting rid of clutch slippage. This reduces the heat that the transmission creates, but the transmission still creates a bunch of heat. More at high speed than low speed. Mine made it up close to 250* on my moab trip a couple of times when I was driving over mountain passes, and that's with a big ass aftermarket transmission cooler on it. No telling what kind of temps I would have seen without the cooler.
Sorry for the auto transmission hijack. My fault.
Back to the 4BD!
so, i had a tight fit to get the oil sender on where the stock oil sender goes on the BD1,,, so i located sender on other side above starter in the oil galley plug next to that cap for who know what? i get oil pressure when revved up but goes to zero at idle, anyone know about this? seems kinda wierd, i am using a brand new toyota sender to match my toyota guage, so the electrics and sender and guage should be fine.
BTW i been doing a half ass build thread on the FJ55 section,, its all done and i'm driving it now, such a big smile on my face its stupid.
