Gearbox Getting Hot!

[kristoff]

Hi again guys!

As some of you know I have Toyota Hilux 4x4 with 1uz-fe and lexus autobox

So...the gearbox is getting really warm...even hot!...then after some time it goes away and it is normal.

I have this from begining but usually doing only short trips so it is not bothering me.

atf looks ok and level is ok. what could it be? anyone had same problem?

just to be clear I've just did 1400 miles in one week with this problem(?) and it all seems ok

cheers

The trans fluid is cooled by passing through the lower part of the radiator, do you have the same arrangement?

[steve2006]

The transmission is fitted with a fluid temperature sensor so when fitted in the LS400 there is a warning system for overheating fluid.

Also the LS400 is fitted with a transmission cooler as standard, have you fitted one on the conversion?

Hey Roy great minds think alike :)

[ROYT]

We are ace..!!

[kristoff]

we didn't fit the separate oil cooler. using same rad for both

[steve2006]

So you are using the original combined coolant/transmission intercooler?

the radiator is of Toyota Hilux Surf 3L engine. I am not using separate cooler for transmission

is it still a 4x4? I would say you need to cool the transmission fluid with a cooler of some sort, I'm assuming the Hilux radiator doesn't have transmission lines in/out of it in addition to the engine coolant?
