[Lochie29]

Hi guys i own a 1993 80 series landcruiser and ive got codes 83,84 and 85 which are the transmission control module ive spent all day trying to find the box to see if i have a faulty one but have had no lucky find it i havea a repair manual which is telling me its near the Transmission Fluid Temperature Sensor but can not find that just wondering if anyone knows where it would be.
Thanks

G'day Lochie

I've just spent all morning finding mine as well!

Mine is a '94 1fz and I found the ECT ECU inside on the drivers side, tucked up above the steering column.

It's visible from the foot-well but a bit of a pain to access for diagnostics

i have found my ECU and ECT but not the TCM is the TCM apart of the ECU or is it a different box as i can not find it

Yeah sorry mate looks like your model used a different transmission management system. These relate to your issue. Good luck

A442F shifting from 1st directly to 3rd

So I found the right page in the FSM. 83-85 point to the ESA (Electronic Spark Advance) Circuit link between the ECU and TCM. But since its the entire ESA circuit from the TCM is throwing a fault I'm thinking that the TCM is having an intermittent input from one of the sensors.
